Instead of doing a bit of everything, I stick to three lanes — and ship production-grade, maintainable code in each.
Business sites, portfolio pages and landing pages designed for conversion, not just looks.
Moderation, economy and integrations tailored to how your server actually works.
Client portals, dashboards and internal tools built mostly on Next.js.
No surprises along the way — you know where things stand at every stage.
We talk through the goal, audience and budget.
You get a clear scope and price range in writing.
Built in iterations — you see progress, not just the final drop.
I ship to production and check everything live.
I stick around after launch — fixes, growth, questions.
Selected work — websites, Discord bots and web apps, from idea to launch.

A few words about working together — from the people I've built a site, bot or app for.
Patrycja W.PhotographerPatrzWspomnienie Strona WWW ↗PatrzWspomnienieI wholeheartedly recommend Kacper to any photographer dreaming of a beautiful, professional website! 🤍 I was looking for something unique—a site that would be minimalist, elegant, and perfectly reflect the character of my photography and my brand. Kacper understood my vision perfectly and took care of every single detail. A huge advantage is that he truly understands the needs of photographers and knows how important it is to showcase images effectively—after all, they are our calling card. Great communication, patience, dedication, and complete professionalism at every stage of the process. The final result is exactly what I had hoped for! If you are a photographer considering building your own website, I definitely recommend Kacper! 🤍
Full-stack developer
I build websites, Discord bots and web apps — from the quote, through launch, to support after your project goes live.
I work alone, so you talk directly to me, not to a middleman. Day to day I write Next.js and TypeScript, and bots in discord.js.
It depends on the package. Websites: Basic (a simple brochure site) 3–5 working days, Pro 1–2 weeks, Custom from 3 weeks. Discord bots: from 1–2 working days (Basic) to 1–2 weeks and more (Custom). Web apps: from 1–2 weeks (Basic) to 6 weeks and more (Custom). I give a binding deadline in the quote.
Typically a deposit upfront and the rest on delivery. We agree on details before the start.
Yes, I can provide hosting and technical support after launch.
No — the bots I build also run on business servers and product communities.
Yes, once the project is paid in full I hand over full rights and the source code. The exception is Discord bots — the bot's source code costs an extra 100 PLN.
Yes — once the project is settled I issue an invoice or a receipt, whichever you need. You give me the details for the document before work starts.
I show progress as I go and collect your feedback, and small fixes within the agreed scope are included in the price. If the result doesn't match what we agreed, I fix it. You can also cancel before the project ends — we then settle only the part already done (details in the Terms).
Pro packages include one month of care after launch (for Discord bots — hosting for the first month). Ongoing maintenance and support are quoted separately, depending on the project — you'll see the amount in the quote before work starts.
Fill in the form or reach out directly — whichever works better for you.
