Shipping Flutter, FastAPI, and AI systems since 2019. Reviews the architecture on every engagement.
Mobile apps, backend systems, frontend surfaces, and AI integration. Named stacks, named outcomes, honest trade-offs.
Three honest starting points. Pick the closest — the page will route you to the right deep dive.
Decision pages set the fork in the road. Specialist pages go deep on the stack.
iOS and Android apps built on Flutter, React Native, or native. Platform pick, stack pick, partner pick - decided before week one, not regretted at week ten.
FastAPI on the hot path. Postgres as source of truth. Redis for cache. Celery for jobs. WebSocket or Socket.IO for real-time. CI deploys that do not page you on a Friday.
Web apps that are fast on real networks. React with Next.js for app shells, Astro for content-first sites, same component system underneath. Built for 95+ Lighthouse, not just spec compliance.
Flutter apps for iOS, Android, iPad, and web from one Dart codebase. Named state management, typed backend contracts, store pipelines that ship on a Tuesday.
React Native for teams already writing React and TypeScript. New Architecture, Expo, OTA updates, native modules when a library falls short.
React web apps on Next.js App Router. Server Components, TanStack Query, Tailwind + shadcn/ui. Fast by default, typed end to end, tested where it counts.
LLMs, RAG, and agents wired into production apps. Server-held keys, swappable models, measurable output. Not a ChatGPT wrapper.
You speak to the person who’ll review the architecture. No account-manager layer. No offshore switcheroo.
Scoping is free. 20 minutes on a call and we’ll tell you the stack we’d pick and why.
