Software you own. Built to last.

Custom software

We run our own products in production. Your build gets the same standard.

Custom web apps, mobile products, internal tools, and AI agents — built for production, not demos.

That means typed codebases, tested deploy pipelines, and documentation your team can run without us — built in Staten Island, shipped worldwide.

What we build

Web App Development

Next.js · TypeScript · Auth · Billing · APIs

Production web apps with auth, billing, data models, and admin surfaces that scale with your business. Next.js, typed APIs, and observability baked in — so you launch once and iterate with confidence.

What you get

A shippable web product with auth, billing, and admin — not a UI mock that dies in Figma.

Mobile App Development

iOS · Android · React Native · Push · Offline

iOS and Android apps built for retention, performance, and a polished user experience. Cross-platform where it pays off, native where it matters — always designed around the workflows your users actually run.

What you get

Store-ready mobile builds with push, offline paths, and a UX your users will keep opening.

Internal Business Apps

Dashboards · Admin · Workflows · Integrations

Admin panels, ops dashboards, and workflow tools your team will use every day. Consolidate spreadsheets and tribal knowledge into one system with roles, audit trails, and the integrations you already depend on.

What you get

One internal system that replaces spreadsheet chaos — roles, audit trails, and the integrations you already pay for.

AI Agent Development

Agents · Copilots · RAG · Tool use · Guardrails

Agents that take work off your plate — grounded in your data, wired into the systems you already run, with guardrails for cost, quality, and escalation to a human when it counts.

What you get

An agent in production with tool access, evals, and a clear human handoff — not a chatbot demo.

Outcomes you can hold us to

Written into how we work — not aspirations on a slide. If one of these slips, you'll hear it from us first.

Clear scope and architecture before build starts
Production-ready auth, billing, and data models
Dashboards, portals, and customer-facing products
Handoff with docs and repos your team can own
Weekly demos so progress is always visible
Observability and deploy paths that survive growth

How a build runs

The expensive decisions happen before the build; the progress happens in the open. Every step ends with something you can hold.

Scope

Discovery is timeboxed. We map the workflows that matter, kill weak ideas early, and fix scope before a line of production code is written.

You get: A fixed scope, timeline, and quote.

Architect

Data model, auth, integrations, and deploy path get decided up front — the parts that are expensive to change once the build is moving.

You get: An architecture you can challenge before we build on it.

Build

Working software every week — demos of the real product, not status decks. Change requests get scoped and priced in the open.

You get: Visible progress. No silent scope creep.

Hand off

Repo transfer, documentation, and a deploy pipeline your team can run. We stay through stabilization instead of disappearing at launch.

You get: A system your team owns on day one.

What you get at handoff

You own everything on day one.

Handoff is a deliverable we engineer — not a zip file on the way out. Here is what changes hands when the build ships.

The repo — yours outright

Full source with history, transferred to your organization. No licensing traps, no hostage codebases, no vendor lock.

Documentation & runbooks

Setup guides, architecture decisions, and day-two runbooks written for the next engineer — even if that engineer isn't us.

CI/CD deploy pipeline

Automated build, test, and deploy with smoke checks. Shipping a fix doesn't depend on us being awake.

Tests & observability

Coverage where it protects revenue, plus error monitoring and logging wired in — so you see problems before customers do.

Environments & credentials

Production, staging, and secrets handed over cleanly — documented, access-controlled, and under your accounts.

30 days of stabilization

After launch we stay on for fixes, tuning, and questions. Then run it yourself with the docs, keep us on retainer — or let us host and run it for you.

This is the standard we hold our own products to — ByteSize VMS and Studio run in production today, on pipelines we built and still operate.

Two ways to work with us

Both come with the same engineering standard. The difference is whether we ship one product — or keep building with you.

Ongoing product partner

A senior engineering team on retainer.

For products that keep evolving after launch — we run the roadmap, the day-two operations, and the next build.

  • Continuous roadmap — build, iterate, extend
  • Day-two ops: hosting, monitoring, fixes, upgrades
  • Architecture and stack decisions owned end to end
  • Scales up or down with your roadmap

Where most fixed-scope builds land once the product proves itself.
