From 30 minutes to a full build
Pick your way in
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.
01Audit
FREENO COMMITMENT
30 min with a full-stack dev
A 30-minute teardown of your product, stack and UX, plus a short written report. The lowest-friction way to start.
02Renovation
Legacy module renovation
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.
03Consolidation
SaaS consolidation
Replace your tangled stack of separate CRM, ERP and invoicing tools with one system you own — built on a proven open-source core, the 80% that is already built and tested, tailored the last 20% to fit your business.
04Automation
Workflow automation sprint
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.
05Configurator
Product configurator & instant quote
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.
06AI assistant
AI assistant for your product
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.
07Migration
System & data migration
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.
08ERP sync
Sync your desktop ERP with the web
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
The software your business runs on
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.
Custom ERP & business systems.
One system to replace the spreadsheets and half-fitting SaaS your business runs on — built on a proven core, owned by you.
Explore →Manufacturing & production systems.
Production planning, BOM and made-to-order quoting — the parts a boxed ERP leaves out.
Explore →Order management & ERP integration.
One cockpit for orders across your store, marketplaces and warehouse — synced with the ERP you already run, even one with no API.
Explore →Custom CRM & sales operations.
A CRM shaped around how you actually sell — quote history, inbox-to-lead parsing and AI-drafted offers included.
Explore →Booking & reservation systems.
Availability, scheduling and online payments — from a booking flow on your site to a full two-sided marketplace.
Explore →Payments, wallets & ledgers.
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
One team behind every offer
Everything above is delivered by the same full-stack team. Whatever your project needs, it’s in the building.
Web & frontend.
Production React/Next.js apps, design systems, and dashboards that stay fast as they grow.
Explore →Mobile.
Cross-platform apps from one codebase, plus native iOS/Android where it counts.
Explore →Backend & APIs.
Typed services, clean data models, and APIs built to scale without surprises.
Explore →Cloud & DevOps.
Reproducible infrastructure as code, CI/CD, and observability — no console drift.
Explore →AI & agents.
LLM features, RAG, and agent orchestration wired into real product workflows.
Explore →Data & integrations.
Pipelines, third-party integrations, and the glue that makes systems talk.
Explore →Not just delivery
Need a technical leader, not just a team?
Some teams have the builders but need the call-maker. That role is available on its own.
09Leadership
ADVISORYMONTHLY
Fractional CTO & technical leadership
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.
Bring the napkin sketch.
Thirty minutes with a full-stack engineer, plus a short written report that's yours to keep.
