Free AI-readiness & UX audit
A 30-minute teardown of your product or stack, plus a short written report. The lowest-friction way to start.
Start here
Defined, fixed-price ways to work with us. Start small, no big commitment — each one is a fixed scope, a fixed price, and a working deliverable.
A 30-minute teardown of your product or stack, plus a short written report. The lowest-friction way to start.
Pick one tired module of your product — the slow one, the buggy one, the one nobody wants to touch. We renovate it: modern, tested, shipped in weeks, not months. Fixed price, fixed scope.
Replace your tangled stack of separate CRM, ERP and invoicing tools with one system you own — built on Open Mercato, the proven open-source 80%, tailored the last 20% to fit your business.
Pick the most painful manual workflow in your business. In a fixed two-week sprint we automate it end-to-end — built, tested, and running in production.
For made-to-order products, replace the free-text “contact us for a quote” with a configurator: your customer picks the parameters, sees an instant ballpark price, and sends a complete, structured inquiry — no more back-and-forth just to find out what they need.
Add a working AI assistant to your product — a tutor, copilot or support agent that knows your domain, answers from your data, and does real work through tools. Built with the evals and guardrails to keep it honest, not a chatbot bolted on.
Get off an old system without betting the company on a big-bang rewrite. We build the new system alongside the live one, move your data with an idempotent, re-runnable tool — never a one-shot script — and prove old and new match against a copy of your real data before anyone cuts over.
Subiekt GT, Streamsoft and other desktop ERPs weren't built for the web — so orders, stock and invoices get re-keyed by hand between the ERP and your store, Allegro or warehouse. We build a self-healing, near-real-time sync, even for systems with no API at all, so both sides finally agree — automatically.
Systems we build
Custom operational systems on a proven open-source core — Open Mercato. One pillar, sharpened into the domains we’re deepest in — from the shop floor to sales, bookings and payments.
One system to replace the spreadsheets and half-fitting SaaS your business runs on — built on a proven core, owned by you.
Explore →Production planning, BOM and made-to-order quoting — the parts a boxed ERP leaves out.
Explore →One cockpit for orders across your store, marketplaces and warehouse — synced with the ERP you already run, even one with no API.
Explore →A CRM shaped around how you actually sell — quote history, inbox-to-lead parsing and AI-drafted offers included.
Explore →Availability, scheduling and online payments — from a booking flow on your site to a full two-sided marketplace.
Explore →Stripe payments, multi-currency wallets and append-only ledgers that reconcile to the cent.
Explore →In build right now: an OMS syncing tens of thousands of orders a month, a metal-fab ERP and an eSIM wallet.
Full-stack, end to end
Everything above is delivered by the same full-stack team. Whatever your project needs, it’s in the building.
Production React/Next.js apps, design systems, and dashboards that stay fast as they grow.
Cross-platform apps from one codebase, plus native iOS/Android where it counts.
Typed services, clean data models, and APIs built to scale without surprises.
Reproducible infrastructure as code, CI/CD, and observability — no console drift.
LLM features, RAG, and agent orchestration wired into real product workflows.
Pipelines, third-party integrations, and the glue that makes systems talk.
Not just delivery
Some teams have the builders but need the call-maker. That role is available on its own.

Senior technical judgment without a full-time hire — architecture and stack decisions, build-vs-buy calls, technical due diligence, and the standards that keep a team shipping. Led personally by Jack Tomaszewski: 20+ years across TypeScript, infrastructure, commerce and AI, with the conference talks and merged open-source PRs to back it.
