Services
Engineering, product, and growth — under one roof.
Fletcher Hills Systems runs like a product team, not a dev shop. We ship real software on modern stacks, wire it into your payments and analytics, and stay around long enough to grow it.
What we build
Across every engagement, this is the surface area we cover — solo or in parallel.
Full-Stack Web Apps
End-to-end product builds on Next.js + Supabase / Firebase. Auth, RLS, real-time data, background jobs, CI/CD — shipped to your domain.
AI & LLM Integration
Claude, OpenAI, and Gemini wired into your product: chat, RAG, agents, document summarization, voice, code tooling. Private data in, typed outputs.
Marketing Sites & SEO
Conversion-tuned Next.js static sites with schema.org, GA4, GTM, Meta Pixel, Core Web Vitals < 2s. Deployed to Vercel or Firebase.
Marketplaces & Platforms
Two-sided and multi-tenant platforms with Stripe Connect, Firestore or Postgres, role-based access, and operator admin UIs.
Payments & Subscriptions
Stripe Checkout, Stripe Connect, webhooks, metered billing, customer portals, refunds. PCI-safe patterns, real production handling.
Performance & Audit
Deep audits of an existing app: security, query performance, Lighthouse, bundle analysis, accessibility. You get a written report + PR.
Admin Panels & Internal Tooling
Operator surfaces for non-technical teams: CRUD UIs, dashboards, queue monitors, content managers. React / Next.js / shadcn-based.
Game & Interactive Builds
Web-first indie games (Phaser / Unity WebGL) with first-class commerce, player accounts, and music/asset marketplaces built in.
How we work
Four operating principles that hold across every engagement.
Tight scopes, real timelines
Every engagement starts with a written scope and a dated timeline. No vague hourly bill, no scope creep — just the work we agreed to.
Production-grade from day one
TypeScript end-to-end, typed schemas, tests where they matter, CI/CD, monitoring. When you inherit the codebase, it's acquisition-ready.
Founder-direct communication
You talk to the engineer shipping the code. No account managers, no PM overhead — just fast answers and weekly shipping demos.
Your stack, your domain
We deploy to your domain on your hosting. Code lives in your GitHub org. You own everything from week one.

Every project gets a free 30-minute scoping call. You leave with a written scope, a dated timeline, and a fixed quote — even if we don't end up working together.
