We build complete, production-ready products. Not MVPs. Not prototypes. The real thing, architected to scale, delivered in weeks.
Twenty years of production software for

















No committees. No bloated timelines. No "phase one" that never reaches phase two. One senior team, full ownership, relentless pace.
We learn your business in days, not weeks. Architecture, data model, and technical strategy defined before a line of code is written.
Every layer, simultaneously. Mobile, web, backend, payments, infrastructure. Working software delivered weekly.
Production deployment, monitoring, analytics, and handoff. You launch with a product that works, not a project that needs more work.
Agencies sell you hours. We sell you a product that makes money.
iOS and Android from day one. Real-time maps, payments, push notifications, camera. App Store ready at launch.
Multi-sided systems that connect users and move money. Buyer meets seller, host meets guest, provider meets customer.
AI as a core feature, not a gimmick. Voice assistants, intelligent automation, data pipelines, recommendation engines.
Internal platforms, operations dashboards, analytics systems. The software your team needs to run the business.
AI used as a system, not a chat window — and the validation layer that keeps it honest. Staging-backed integration tests over mocks, generated changes reviewed against current state, drift audited before it bites.
Profiling, root-cause analysis, and regression detection on products that got slow. Memory growth, cold-start stalls, main-thread contention. Fixed and verified by measurement, not assumption.
Two decades of consulting delivery, mostly for companies where the software already carries revenue and a regression is measured in dollars rather than tickets.
// Work delivered under NDA. Engagement detail available on request.
Three engagements across finance, retail, and industrial systems.
Rebuilt the entire client-side authentication experience from scratch: registration, login, password reset, and multi-factor enrollment with SMS and IVR verification. Every service interaction was mocked in Node against Swagger specifications while a separate team built the real endpoints, so the front end shipped without waiting on the back.
Built promotional pricing and "Buy Now" flows on the highest-traffic retail checkout in the United States, plus the product substitution experience: when an item goes out of stock during online grocery fulfillment, the system presents intelligent alternatives instead of dropping it from the order. Covered by integration tests against mocked GraphQL, because on a checkout path you do not get to find out in production.
Data-dense visualizations of tank levels, flow rates, and alarm conditions over time for next-generation fuel-management consoles, in systems deployed across roughly 80% of North American fuel stations. Correctness and legibility under heavy data load were the entire job.
The clearest way to judge a studio is what it builds when nobody is paying it to.

A cross-platform consumer application built and operated entirely in house: React Native and Expo shipping iOS and Android from one codebase, a PostgreSQL data layer with 500+ migrations, row-level security, stored functions and edge functions, a Next.js operations console with live analytics and real-time geospatial monitoring, Stripe payments, localization across 25 languages, a conversational assistant on Claude tool-use with Whisper speech-to-text, and an automated ingestion pipeline that aggregates and deduplicates event data across a large number of third-party sources.
We take on a handful of projects at a time. If you have an ambitious idea and need it built right, let's talk.
