Summary: A European e-commerce company with €80M annual revenue needed to rebuild its ageing platform from the ground up. The existing monolithic system couldn't handle traffic spikes, mobile conversion was poor, and the local development team of 10 was too small and too expensive to scale.
Expedite Software Services assembled a 25-engineer offshore development team that designed, built, and launched the new platform in 10 months — 60% faster than the client's original 24-month onshore estimate.
Replace a 10-year-old monolithic e-commerce platform with a modern, microservices-based architecture.
Support 10M+ monthly visitors and 500K+ orders per month with auto-scaling infrastructure and sub-2-second page loads.
Increase mobile conversion rate from 1.2% to 3%+ with a responsive, performance-optimised mobile experience.
Launch the new platform in under 12 months — 60% faster than the original 24-month onshore development estimate.
Support 6 European markets with localised pricing, multi-currency checkout, and region-specific logistics integrations.
Achieve 50%+ cost savings versus building and maintaining a local European development team of equivalent capacity.
Node.js (NestJS), Python (FastAPI), PostgreSQL, Redis, RabbitMQ
Next.js, React, TypeScript, TailwindCSS, Storybook
AWS (EKS, Aurora, ElastiCache, CloudFront), Terraform, Helm
Elasticsearch, Algolia, custom recommendation engine (Python/ML)
Stripe, Adyen, multi-carrier shipping APIs, VAT compliance
GitHub Actions, ArgoCD, Cypress, Playwright, k6, Lighthouse
Page load times averaging 6+ seconds on mobile — causing a 68% mobile bounce rate and 1.2% mobile conversion.
Platform crashing during peak sales events (Black Friday, seasonal campaigns) — losing an estimated €2M per event.
Any feature change required full regression testing and deployment of the entire monolith — 3-week release cycles.
European senior engineers costing €120K+ annually — building a 25-person team locally would exceed the project budget by 2x.
25-engineer team: 10 full-stack, 4 backend, 3 frontend, 3 DevOps, 3 QA, 1 architect, 1 delivery manager.
15 independent microservices — catalog, cart, checkout, payments, inventory, shipping, user, search, recommendations.
Server-side rendering with Next.js, edge caching via CloudFront, image optimisation, and lazy loading — sub-1.5s LCP.
Kubernetes-based auto-scaling handling 10x traffic spikes — load-tested to 50K concurrent users before launch.
Strangler pattern migration — new services deployed incrementally while the old monolith was decommissioned module by module.
Localised for 6 markets simultaneously — multi-currency, multi-language, region-specific shipping and tax rules.
Platform launched in 10 months vs. the original 24-month estimate — capturing 2 peak shopping seasons the client would have missed.
Mobile conversion rate improved from 1.2% to 3.1% — driven by sub-1.5-second load times and mobile-first UX.
Zero downtime during Black Friday (12M visitors in 48 hours) — auto-scaling handled 10x normal traffic seamlessly.
Total development cost 55% lower than the onshore estimate — ongoing maintenance at 50% of European team rates.
All 6 European markets launched simultaneously — multi-currency checkout, localised content, and region-specific logistics.
Moved from 3-week monolith releases to weekly microservice deployments — 15x more feature releases per quarter.
