Draft plan

A draft will appear here: diagnosis, solution, timeline and goal.
Apps and AI that get the job done.
I make websites for businesses and build web and mobile apps — from the first MVP to a mature product. Where it pays off, I add AI and automations that keep working while you sleep.

Approach
Tell me what hurts.
I’ll show you a plan.
Every project starts with your problem, not with technology. Pick the one that sounds familiar.
How I can help
From a website
to AI at work.
We usually start with a website that brings in customers. As the business grows, apps and automations follow. Always with a working preview every 1–2 weeks.
Websites for businesses
A modern website that looks good on a phone, loads fast and can be found on Google. Customers see straight away what you offer and how to reach you.
- Design shaped around your customers
- Fast and easy to use on a phone
- SEO from the ground up and a Google Business Profile
- A new website or a refresh of the old one
- Domain, hosting and care after launch

From an idea to a working app you can show your customers — in weeks, not quarters.
- Web and mobile apps (iOS, Android)
- Backend, APIs and integrations with your systems
- Chats, assistants and content generation

- Documents, invoices and reports without retyping

About
An engineer, not
an AI salesman.
For over 10 years I’ve been building web and mobile apps for teams around the world, from food to fintech. Today I combine that with generative AI, with one rule: the model has to deliver results, not a conference demo.
I believe in small, fast releases, clean code you can take over without pain, and an honest “this makes no sense” when it doesn’t.
Process
How we
work together.
No months of analysis and no black box. Every 1–2 weeks you see a working version and decide what’s next.
Let’s start with a call-

The code is yours. 100%.
Repository, documentation, infrastructure. We keep building together, or you take the project over.
Testimonials
Messages I
love to get.
Every YouTube video I make now turns into an SEO-optimised blog post — completely automatically. Hours of manual work disappeared overnight, and organic traffic has finally started to grow. Straight to the point, no fluff.
We worked on the same project for almost two years, and I know one thing — his code barely needs a tester. Committed, focused and one of the best frontend developers I’ve worked with in seven years of QA.
Simply put, bookings went up. The new site is fast, mobile-friendly and gives our vintage wedding taxi exactly the elegant image it deserved.
Sebastian worked closely with us at every stage — from structure and content to the technical side. The result is a clear, fast-loading website that communicates exactly what we do and makes it easy for clients to understand our services.

Hi! Click a question on the leftPick a question below — I’ll answer right away.
With a 30-minute call. You tell me what you want to build or improve, I ask questions and tell you straight what makes sense. Then you get a concrete plan and a quote.
It depends on the scope. After a short call you get a clear quote and timeline — no hidden costs and no surprises along the way.
Usually within 1–2 weeks — that’s when you get the first working demo. Simple automations are often ready even sooner.
Yes, and it’s often the best idea. A small MVP or a single automation quickly shows whether it’s worth going further.
Often yes, but not always. On the call I’ll show you concrete use cases for your business — or tell you straight that it’s not worth the money.
100%. You get full access to the repository, documentation and infrastructure.
We can keep developing it together, or you take it over with clean, documented code — with no dependence on me.
Yes, with clients all over the world. I work from Poland (CET), with a comfortable overlap with the UK and the US East Coast. We talk on Slack, by e-mail and on video calls.
Yes, for small and large ones. It’s a big part of my work today. I design and build company websites that look good on a phone, load fast and can be found on Google. I work with businesses in Poland and abroad.
