Oprogramowanie B2B · Full-stack · AI
Websites, stores, AI and platforms designed to scale.
I design and ship systems end to end — from sites that load in under a second, through stores and automation, to platforms handling real traffic. Decisions on numbers, code owned by the client.
From landing page to platform — one person accountable for the wholedowozimy całość
Six areas that connect into one coherent system. Each has its own page with a reference architecture and scope.
Websites & web apps
Fast company websites, landing pages and web applications in Astro, Next.js, React and Vue.
DetailsOnline stores
WooCommerce and headless commerce with payment, shipping and ERP integrations. A fast checkout.
DetailsPerformance optimisation
Audit and fix of Core Web Vitals, backend and database. Hard numbers before and after.
DetailsAI integration
RAG over company documents, tool-using agents, model routing and LLM cost control.
DetailsLarge-scale applications
Platforms and SaaS in NestJS, Node, Python and Go. Queues, event-driven, Kubernetes, observability.
DetailsBusiness automation
System integrations, document flows, reports and notifications. Processes running in the background.
DetailsSpeed is a product feature, not an extrafunkcja produktu
Every site and store I build has a performance budget and Core Web Vitals monitoring. Toggle to see a typical before/after optimisation.
Resource loading
Four stages. No surprises.Zero niespodzianek.
You know what happens every week and what you pay for.
week 1
Diagnose
Workshop, audit of code, infrastructure and metrics. We set the business goal, constraints and risks.

1-week iterations
Deliver
Weekly demo, a preview of every change, tests and CI/CD from day one.

Frequently askedpytania
01Who do you work with?
Startups, software houses and companies that need a senior on a key project — from a new site or store to platform architecture and AI rollout.
02What is the engagement model?
B2B: fixed-scope projects (fixed price after a discovery phase) or ongoing time & materials / retainer. VAT invoice.
03Do you take over existing projects?
Yes. I start with a code and infrastructure audit, then present a plan: what to fix now, what to refactor in stages, what to leave alone.
04How long does it take?
Company site: 2–4 weeks. Online store: 4–10 weeks. Platform or AI rollout: depends on scope, always iterative with a working demo.
05Does AI make sense for my business?
We test it on a concrete process and your data. I build a quick proof of concept with quality and cost evaluation — the decision is made on numbers.
06Do you provide maintenance?
Yes — monitoring, updates, further development. I can also document the system and hand it over to your team.
