End-to-end product engineering for businesses that need performance, reliability and craft — from the first line of code to production, and beyond.
Architecture, design, build, deploy, observe. One team owns the whole line — no hand-offs, no finger-pointing.
High-performance web apps with Next.js, React and .NET backends. Server-rendered, SEO-ready, measured in milliseconds.
Native iOS & Android from a shared React Native / Expo codebase — push notifications, deep links, offline-first where it matters.
Cloud-native .NET with Clean Architecture, CQRS, gRPC and real-time SignalR — built to grow from one shop to thousands.
LLM-powered features that ship: intelligent imports, copilots, automation — with cost controls and guardrails baked in.
We map the domain, pick boring-where-possible technology, and design for the scale you'll actually hit.
Unit, integration and E2E suites from day one — Testcontainers, Playwright, NBomber. Quality is not a phase.
CI/CD pipelines to cloud platforms with zero-downtime releases, staged rollouts and instant rollback.
OpenTelemetry traces, metrics and logs on every request. We see problems before your users do.
Great software is built through craft, not shortcuts. We work with businesses to deliver solutions that are maintainable, observable, and built to last.
We stay on the industry's cutting edge — .NET 10, React 19, cloud-native patterns, comprehensive testing and full observability stacks.
Multi-tenant marketplace serving retail customers, restaurant owners and back-office ops — built and run end-to-end by Software First.
