Product discovery
Lightweight discovery sprint: user flows, data model, scope cuts and a fixed-price proposal. You leave week two knowing what we're building and what it costs.
Web applications
Custom web apps — shipped end to end.
A senior product engineering team that designs, builds and operates the web applications behind your business — from internal tools to AI-powered SaaS.

What you get
Design & prototyping
Figma flows and interactive prototypes — validated with real users before we write production code. Cheaper to throw away than to refactor.
Full-stack engineering
React, TanStack Start, edge functions, Supabase / Postgres, queues, and third-party integrations. Senior engineers, no offshore handoff.
AI features
RAG, agentic flows, model routing and evals — built on top of mature gateways with observability and cost controls. Production AI, not a demo.
Auth, billing & permissions
Production-grade auth, Stripe/Paddle billing, role-based access — the boring foundations done right so you don't refactor them in year two.
Ops & handover
Monitoring, error tracking, CI/CD, and a documented handover to your team or ours on retainer. We leave the codebase better than we found it.

Want a 20-minute teardown of your current setup?
No deck. We screenshare, point at the gaps, send notes after.
How we work together
Fixed sprint
6–12 week build
- Fixed scope and price
- Production-ready handover
- Best for MVPs
Embedded team
Ongoing partnership
- 2–4 engineers in your sprints
- Quarterly roadmap reviews
- Best for scaling products
Advisory
Fractional CTO
- Architecture and hiring help
- Code review
- Half-day per fortnight
Our point of view
Most agencies will hand you a working demo and walk away. We treat shipping to production as the easy part — keeping a codebase you'd happily inherit is what separates a real engagement from a contractor invoice.
Frequently asked
What kinds of apps do you build?+
Customer portals, internal tools, dashboards, AI-powered products, marketplaces, and SaaS MVPs. If it lives in a browser and needs auth, billing or a database, we can ship it.
How fast can you ship an MVP?+
Most MVPs go live in 6–10 weeks. We work in two-week sprints with weekly demos, so you're never surprised by what's coming.
Do you handle hosting and ops?+
Yes — we deploy on edge runtimes (Cloudflare, Vercel) with managed databases. You get a production-grade setup without hiring a DevOps team.
Will we own the code?+
Always. Code lives in your GitHub from day one, documented, with a handover that a future team can pick up cleanly.
