Custom Web Applications
Built Right the First Time
Anyone can generate a web app that looks finished in a demo. The gap is what happens when real users show up — auth, security, data integrity, and scale. We build production-grade applications on Next.js, React, and Postgres, with that 20% handled from day one.
A production-grade web app is the last 20% that AI tools and cheap builds skip: authentication that can't be bypassed, real error handling, a data model that stays correct under load, and performance that holds as you grow. It's the difference between a demo that impresses and an application that survives real users. That's what we build — fixed price, in weeks, and the code is yours.
Production-grade, front to back
Full-stack builds
Next.js, React, and TypeScript front to back — a real application, not a template, architected to stay readable and extendable as it grows.
Auth & access control done right
Sessions, roles, and permissions that can't be bypassed — the part that most often ships wide open, built and verified as a logged-in user.
Databases & data integrity
A Postgres or Supabase data model that stays correct under real use — proper relations, constraints, indexes, and versioned migrations.
Payments & integrations
Stripe billing, webhooks, and third-party APIs wired in cleanly, with the edge cases handled — not just the happy path in a demo.
Performance & scale
Fast page loads and queries that hold up as traffic and data grow, with error handling and observability so failures surface instead of hiding.
Handover & ownership
Your GitHub, your hosting, your keys — clean code and a written handover so any engineer can take over. No lock-in to us.
What “production-grade” actually includes
The gap between a demo and a real application is a concrete list — and it's where most builds get breached. Broken access control is the #1 risk in the OWASP Top 10 (2025), and Verizon's 2025 breach report found 88% of attacks on web apps used stolen or weak credentials. These are the specific things we build in from day one:
Auth and access control tested by trying to bypass it — not just assuming logged-in means allowed
Authorization enforced server-side on every request, never trusted from the browser
Input validation and rate limiting on every endpoint
A data model with real constraints, foreign keys, and versioned migrations, so bad data can't be written
Error handling and boundaries so one failure doesn't take the whole app down
Monitoring, logging, and alerts so failures surface instead of hiding
Automated backups and a restore that has actually been tested
Performance budgets — fast loads and queries that hold up as traffic and data grow
Real products, live in production
Not slideware. These are custom web applications we designed and built end to end — with auth, data, payments, and AI wired in — and they're running with real users today. Need the smallest launchable version first? That's our MVP development track, same standard.
