Custom web development built to survive success
Custom platforms, e-commerce, and internal tools in React, Next.js, and Node.js — architected so the thing that works at 100 users still works at 100,000.
Most web projects don't fail at launch. They fail six months later, when the product catalog triples, a marketing push lands, or someone tries to add a feature and discovers the codebase is held together by assumptions nobody wrote down. We build for that second phase. That means real data modeling before the first screen, sensible caching, queries that don't degrade as tables grow, and a deployment process anyone on your team can run.
We've built high-traffic consumer platforms, industrial e-commerce with hundreds of thousands of SKUs, and financial tools where a stale number is a real problem. The work looks the same at the start: understand the data, understand the users, then write less code than you'd expect. You get a repository with clear structure, documentation for the parts that aren't obvious, and no dependency on us to keep it running.
- A production application on your infrastructure and in your repository, with deployment, environment configs, and rollback documented
- A data model and API designed for your actual query patterns, not a generic CRUD scaffold
- Page performance measured against Core Web Vitals, with server-side rendering or static generation where it helps
- Search, filtering, checkout, auth, roles, and admin tooling built as first-class parts of the product
- Automated tests on the paths where breakage costs money, plus error tracking wired up before launch
- Integrations that hold: Stripe, Shopify, ERP and inventory systems, CRMs, and internal APIs
How we work
Scope in detail
We map the data, the user journeys, and the integrations, then give you a fixed scope and a timeline with the risky parts named up front.
Build the spine first
Data model, auth, and the core transaction path go in early so we're testing the hard parts in week two, not week ten.
Ship to staging continuously
You see working software on a real URL throughout, not slide decks. Feedback goes into the next build, not a change-order pile.
Launch and hand over
We deploy, monitor the first weeks closely, and walk your team through the codebase, infrastructure, and runbook.

Most of the time we work with what you have. We'll audit it first and give you a straight answer: what's worth keeping, what needs replacing, and what a phased migration costs versus a rebuild. Rewrites are expensive and we recommend them only when the math clearly favors one.
A focused application is usually eight to sixteen weeks from kickoff to production. Large e-commerce platforms with catalog, ERP, and search integrations run longer. We break work into milestones so you get usable software well before the final date.
You do, from the first commit. Everything lives in your repository under your accounts. If you decide to take the project in-house or hand it to another team, nothing is locked to us.
Send us the requirements and we'll come back with a scope, a timeline, and the parts we'd argue about.
One business day. From an engineer. No sales sequence.
