Calculation apps
Engineering, cost, sizing or energy calculators. A tested math engine and real-time results.
Dense logic, persistent data, precise interfaces and deliverables the client can take into the physical world. And a clear process, told step by step.

Quoters with rates, discounts, VAT and export to PDF/XLSX. Your sales rep closes deals from their phone.
The client picks sizes, materials and finishes; the app computes the price and sends the order to the ERP or by email.
Parametric models in the browser with Three.js: rotation, layers, measurements and export to OBJ/DXF.
Operations panels: users, metrics, billing, OAuth auth, plans and permissions. Supabase + RLS from day one.
Installable apps, offline mode, automatic deployment on Cloudflare or Vercel, your own domain and careful technical SEO.
No agencies in between. No months of silence. Every week there's something to touch and a decision to make.
You tell me the problem and what you've tried. We come out with a written mini-diagnosis and a first scope estimate.
I turn the conversation into a brief technical document: what gets built, what doesn't, how success is measured, in how many iterations and at what price.
Every Monday we prioritise the week together. The code is in your GitHub from day one. No surprises at the end.
Deploy to production, your own domain, live metrics. Afterwards: monthly hours, enhancements, or you take the code and run it yourself.

Before writing code I reach out to the real users to understand what holds them back. That's how DomesLab's axial cut was born: from a conversation, not an assumption.
I test the product, leave it truly working and documented — not a half-finished demo.
I separate the product logic so it can be extended or maintained without rebuilding it.
Lint, typecheck and tests on every PR. Automatic deployment on every push to main. Every change, reversible.
Custom technical software: engineering calculators, quoting tools, product configurators, in-browser 3D viewers and operations dashboards. Tested logic and persistent data, not templates. If your team keeps redoing a calculation in Excel, or your clients ask for something the market doesn't offer, that's exactly what I build.
Directly, no agencies or middlemen. You talk to the person writing the code. Every Monday we prioritise what's next together and every Friday there's a demo you can touch; no months of silence and no quotes that balloon along the way.
The first technical spec and the fixed quote arrive within 3–5 days of the initial conversation. From there I ship a deployed version every week, with a demo on Fridays. You see real progress from week one, not a single delivery at the end of the project.
You do, from day one. The code lives in your GitHub repository throughout the project. At the close you get a technical handover with a runbook and connected metrics, so you can audit it, extend it with someone else or maintain it yourself, without depending on me.
You choose: a monthly maintenance plan (hosting kept up to date, backups and changes), enhancements by the hour, or you take the code and run it yourself. There's no mandatory lock-in. The goal is for the tool to keep working, whoever maintains it.
A template gives you a shape; I solve your specific logic: the calculation, the business rules, the exports and the integration with your ERP or your email. I keep that logic separate from the rest so it can be extended or maintained without rebuilding the whole product.
Tell me what your team or your clients need. In under 48 hours I'll reply with a diagnosis, a scope estimate and the next decision.
