Our Services
From strategy and engineering to on-site infrastructure, here is the full toolkit Opulus brings to every engagement.
IT Consulting
Strategy before code. Every time.
Most technology problems are not technology problems — they are clarity problems. Opulus starts every engagement with a structured discovery phase that surfaces the real constraints, maps the existing landscape, and defines what success actually looks like before a single line of code is written.
We deliver actionable technology roadmaps, architecture reviews, vendor assessments, and organizational recommendations that your team can execute with confidence. When you bring us in, you get a decade of hard-won judgment applied to your specific context — not a recycled framework from a slide deck.
Stack
Technology Roadmapping
Structured, prioritized plans that translate business objectives into concrete technology milestones with realistic timelines and resource requirements.
Architecture Review & Design
Rigorous assessment of existing systems or greenfield designs, with written findings and actionable recommendations covering scalability, security, and maintainability.
Vendor & Platform Evaluation
Objective, criteria-driven evaluation of SaaS tools, cloud platforms, and third-party integrations — so you choose the right solution, not the loudest one.
Legacy Modernization Planning
Step-by-step migration strategies that de-risk moving off outdated systems without business disruption, using strangler-fig patterns and incremental extraction.
Security & Compliance Audits
Threat-model-led reviews of your infrastructure and codebase, with findings mapped to GDPR, ISO 27001, or sector-specific requirements and clear remediation paths.
Team & Process Enablement
Hands-on coaching for internal engineering teams on code quality, delivery practices, and on-call culture — building capability that stays after we leave.
Native & Cross-Platform Apps
Apps your users will actually keep.
The best mobile app is the one that feels like it belongs on the platform — responsive, snappy, and respectful of the conventions users have built muscle memory around. We write Swift for iOS and Kotlin for Android when the use case demands native fidelity: performance-critical workflows, deep hardware integration, or complex platform APIs.
When a single codebase is the smarter call — budget constraints, tight deadlines, or a feature set that maps cleanly to React Native or Flutter — we build cross-platform without compromising on UX quality. Either path gets the same senior engineering attention and the same production-grade architecture.
Stack
Native iOS (Swift & SwiftUI)
Full-featured iOS apps leveraging Apple platform APIs — ARKit, HealthKit, CoreData, Push Notifications — for premium on-device experiences that respect Human Interface Guidelines.
Native Android (Kotlin & Jetpack)
Modern Android built with Kotlin and Jetpack Compose, optimized for the full Android ecosystem from mid-range to flagship, with full Play Store compliance.
React Native
Shared JavaScript codebase targeting iOS and Android with near-native performance, maintained via Expo or bare workflow depending on native integration depth.
Flutter
Dart-based Flutter apps delivering pixel-perfect, 60fps UIs with a single codebase — ideal for consumer products where visual consistency across platforms is non-negotiable.
Backend & API Integration
REST and GraphQL API design, OAuth 2.0 and biometric auth, offline-first sync strategies, and real-time messaging via WebSockets or Firebase.
Store Submission & CI/CD
Automated build pipelines via Fastlane and GitHub Actions, plus end-to-end App Store and Google Play submission including screenshot generation and metadata optimization.
Websites & Web Apps
Web presence that works as hard as you do.
A website is not a brochure — it is a sales engine, a support channel, and a brand statement running in parallel. Opulus builds web properties that perform on every axis: sub-second core web vitals, accessible markup, SEO-ready architecture, and a CMS your marketing team can use without filing a support ticket.
For complex interactive products — dashboards, client portals, internal tools, SaaS front-ends — we bring the same rigor as our native app work: typed APIs, component design systems, end-to-end test coverage, and deployment pipelines that make shipping a non-event.
Stack
Next.js & TypeScript
App Router, server components, ISR — the modern React stack deployed to the edge for sub-second load times with a type-safe codebase that scales without fragile refactors.
WordPress & Headless CMS
Custom themes and plugins, or headless setups pairing WordPress editorial simplicity with a modern Next.js frontend — built for editors, not just developers.
Web Application Development
Multi-tenant SaaS portals, analytics dashboards, and client-facing tools with role-based access control, real-time updates, and production-grade security.
Design System & Components
Production-grade component libraries with Radix UI and Tailwind, documented in Storybook — a consistent visual language that scales across every surface of your product.
Performance & Core Web Vitals
Systematic LCP, CLS, and INP optimization: image pipelines, font loading, edge caching, and bundle splitting until every page scores green on every device.
Accessibility (WCAG 2.1 AA)
Semantic HTML, keyboard navigation, screen-reader-compatible components, and contrast-compliant design systems — treated as a first-class requirement, not a compliance checkbox.
E-Commerce Shops
Stores engineered to convert.
Every element of an e-commerce site is a decision that affects revenue. We build stores where the checkout is frictionless, product pages are persuasive, and inventory is always accurate — because we have seen what a slow checkout page costs in abandoned baskets.
WooCommerce is our first choice for WordPress-based shops. For brands with more complex needs — multi-currency, custom fulfilment logic, subscription billing — we build bespoke platforms that fit the business model exactly, not the other way around.
Stack
WooCommerce Development
Custom themes and plugins built for performance — multi-currency, tiered pricing, subscription products, and B2B wholesale flows on a WordPress foundation your team already knows.
Headless Commerce
Commerce logic via WooCommerce REST APIs with a Next.js storefront for maximum performance and complete UX freedom — ideal for high-traffic or complex catalogue stores.
Payment Gateway Integration
Stripe, Viva Wallet, and PayPal configured with full SCA/3DS2 compliance, webhook handling, and reconciliation-friendly transaction logging.
Inventory & Fulfillment
Real-time inventory tracking, multi-warehouse stock allocation, backorder management, and shipping carrier API integrations with rule-based rate calculation at checkout.
Conversion Rate Optimisation
Evidence-based UX improvements to product pages, cart flow, and checkout — informed by session recordings, funnel analytics, and structured A/B testing.
Platform Migration
Zero-downtime migrations from legacy platforms (PrestaShop, Magento, Shopify) with full product catalogue, customer data, and order history transfer and integrity verification.
Web Marketing & SEO
Visibility earned, not rented.
Paid traffic stops the moment your budget does. Opulus builds organic search presence and content infrastructure that compounds over time — technical SEO foundations that eliminate crawl waste, on-page optimization grounded in real search intent analysis, and a content strategy aligned to the full buyer journey.
We integrate deeply with your web platform so that SEO is not bolted on after launch but baked into the architecture from day one. Structured data, Core Web Vitals, international SEO, and content production all get the same systematic treatment — measured rigorously and reported in plain language.
Stack
Technical SEO Audit & Fixes
Comprehensive crawl analysis covering indexability, site architecture, canonical signals, Core Web Vitals, structured data validity, and mobile usability — with a prioritized fix list tied to traffic impact.
Keyword Research & Intent Mapping
Cluster-based keyword research using Search Console data and third-party tools, mapped to funnel stage and content format so every page targets a purpose, not just a phrase.
On-Page Optimisation
Title, meta, heading, and internal linking optimisation across your full URL set, with entity-based content improvements that match the semantic expectations of modern search.
Content Strategy & Production
Editorial calendar planning, brief writing, and content production for cornerstone pages, comparison content, and thought leadership pieces that build topical authority in your niche.
Local & International SEO
Google Business Profile optimisation, local citation building, hreflang implementation for multilingual sites, and geo-targeted landing page strategy for multi-market businesses.
Analytics & Reporting
GA4 and Search Console setup with custom dashboards tracking organic traffic, ranking movement, and conversion attribution — metrics that connect SEO investment to business outcomes.
Cloud & DevOps
Ship faster. Sleep better.
Slow deploys, manual processes, and opaque infrastructure are engineering tax. We build CI/CD pipelines that take code from a developer's laptop to production in minutes, with automated testing, rollback capability, and full observability baked in from the start.
Infrastructure is code at Opulus — version-controlled, reproducible, and reviewed like any other change. We have a strong preference for boring, well-understood tools over the tool-of-the-month, and every system we hand over comes with documented runbooks and on-call procedures.
Stack
Cloud Architecture & Migration
Lift-and-shift, re-platform, or full re-architecture migrations to AWS or GCP — including network topology, IAM policy modelling, and production cutover planning with rollback.
Infrastructure as Code
Full Terraform definitions with modular structure, remote state, and environment parity across dev, staging, and production — infrastructure as reviewable as application code.
CI/CD Pipeline Design
GitHub Actions or GitLab CI workflows with automated testing gates, environment promotion logic, and blue/green or canary deployment strategies that minimize release risk.
Kubernetes & Containers
EKS and GKE cluster setup with Helm chart management, horizontal pod autoscaling, network policies, and multi-tenancy isolation for platforms running multiple services.
Observability & Alerting
Structured logging, distributed tracing via OpenTelemetry, Grafana/Prometheus dashboards, and PagerDuty alert routing with documented escalation playbooks.
Cost Optimisation (FinOps)
Reserved instance and savings plan analysis, right-sizing backed by utilization data, spot instance strategies for batch workloads, and monthly cost-per-service reporting.
Retail & ERP Systems
One source of truth across your entire operation.
Retail businesses run on data — and the damage caused by data living in silos (a POS that does not talk to the warehouse, an accounting system fed by manual exports) compounds quietly until it becomes a crisis. Opulus designs integration architectures and implements ERP solutions that eliminate those gaps.
We work with established ERP platforms and custom-built solutions for businesses whose workflows do not fit a standard mould. POS hardware selection, retail floor network infrastructure, staff training, and ongoing support are all part of the engagement — because software nobody uses solves nothing.
Stack
ERP Implementation & Customisation
End-to-end ERP deployment with workflow customisation, data migration from legacy systems, and structured user acceptance testing before go-live.
Point-of-Sale (POS) Systems
Retail POS covering hardware selection, software configuration, barcode and RFID integration, offline mode resilience, and real-time sync with central inventory and accounting.
Inventory & Warehouse Management
Multi-location tracking with automated reorder points, supplier purchase order workflows, goods receipt and returns processing, and cycle count procedures.
E-Commerce & ERP Integration
Bi-directional sync between your online store and ERP — keeping product catalogue, stock levels, pricing, and order status consistent without manual intervention.
Greek Tax & myDATA Compliance
Integration with AADE/myDATA systems, automated invoice issuance, VAT reporting, and accounting ledger export to your finance team's preferred tools.
Retail Analytics & Dashboards
Custom management dashboards tracking sell-through rates, margin by SKU, shrinkage, supplier performance, and store-level KPIs — with scheduled reports that arrive before your morning coffee.
Business Infrastructure for SMBs
The physical layer that everything else runs on.
Enterprise-grade infrastructure is not a luxury reserved for large organizations. Opulus designs and installs the physical IT foundation that lets your team work without friction — structured cabling, enterprise Wi-Fi coverage, managed switches, and security systems that are professionally installed and documented, not improvised.
We handle the full scope from site survey to signed-off installation: cable runs, rack mounting, firewall configuration, CCTV positioning, and workstation setup. You get a system that a new IT provider can walk into and understand on day one — because we document everything and do not hold you hostage to our own support contract.
Stack
Structured Cabling & Network Design
Cat6/Cat6A cabling with proper cable management, patch panel termination, switch stack configuration, and labeled documentation — a network that is easy to troubleshoot at 2 AM.
Enterprise Wi-Fi Deployment
Site surveys and access point positioning for Ubiquiti UniFi or equivalent enterprise systems, delivering consistent coverage and seamless roaming across your entire premises.
Firewall & Network Security
Managed firewall setup with VLAN segmentation separating staff, guest, IoT, and POS traffic, plus VPN configuration for remote access and intrusion detection policies.
CCTV & Surveillance
IP camera selection and positioning for entrances, cash points, and storage areas — with NVR setup, remote viewing apps, motion alerts, and GDPR-compliant retention policies.
Workstation & Server Setup
Hardware procurement, OS and software deployment, domain join or cloud identity (Microsoft 365 / Google Workspace) configuration, and baseline security hardening for every endpoint.
Ongoing Support & Monitoring
Remote monitoring of network appliances, proactive firmware update management, on-site response SLAs, and a single point of contact for all infrastructure issues.
