Marketing sites go down gracefully. Business platforms don’t get that luxury. We build full-stack web applications — ordering systems, customer portals, booking platforms, internal tools — engineered for the day they take real traffic. Fixed scope. Fixed price. You own everything on handoff.
A web application is not a website. A website informs; an application transacts — it takes orders, moves money, holds customer data, and has to be correct every single time. That difference drives everything about how we build: schema design before pixels, load behavior before launch parties, and security headers before the first deploy.
Our stack decisions are boring on purpose. React or Next.js on the front, Node.js services behind it, Postgres as the source of truth — proven tools we run in production ourselves, not résumé-driven experiments on your budget. When a project genuinely needs something else, we say so and explain why.
And because we run our own software in production in Chicago, every claim we make about uptime, load, and failure handling is one we live with daily. Our ordering platform on Devon Avenue takes real orders and real payments every night — the same engineering standards go into what we hand you.
Responsive, accessible interfaces in React or Next.js — fast first paint, honest loading states, and keyboard-navigable by default.
Node.js services over a Postgres schema designed for your actual queries — not an ORM default you fight for years.
Sign-in, sessions, and permission tiers built on proven auth patterns — least privilege from the first migration.
Card, wallet, and POS-linked payment flows with idempotent processing and honest failure paths — no double charges, no silent losses.
Content-Security-Policy, strict headers, input validation, and dependency review — shipped with the build, not bolted on later.
Real-device performance budgets, image pipelines, and caching strategy — measured against field data, not lab vanity scores.

View the case study →Every project is priced as a fixed-scope statement of work, agreed before we start — so the honest answer depends on scope, not a rate card. A focused internal tool and a customer-facing transactional platform are very different builds. The discovery call is free, and you get a written brief with a number and a date within 48 hours.
React and Next.js on the frontend, Node.js on the backend, and Postgres for data are our defaults, because we run them in production ourselves. If your project genuinely calls for something different, we will recommend it and explain the trade-offs in writing.
Yes. We start with an architecture and security review of the current codebase, give you a written findings report ranked by severity, and then propose a fixed-scope plan — whether that is stabilizing what exists or rebuilding the parts that cannot be saved.
Yes, completely. On handoff you own the code, the repositories, the cloud accounts, and the domains. We call it the digital handoff, and it is the same on every engagement.
Every launch includes 30 days of post-launch support. After that, you can run it yourself with the documentation we hand over, or keep us on a monthly product partnership for ongoing engineering.
