About me

Modern business websites and apps, tailored to you

Simple process, measurable results and post-launch care — that’s my approach to web development.

About me

B.Eng. in Computer Science — University of Opole

I design web applications because I like solving real problems with simple, effective tools. I combine clean interfaces with solid engineering so your site is fast, secure and easy to grow.

I combine interface design with engineering. We start with a short call to define the business goal, then I prepare a screen draft and feature plan. After approval I build, show weekly progress and deploy without downtime.

I focus on fast load times, accessibility and technical SEO so the site works great on mobile and performs well in Google. The code is clean and ready for future growth.

I work remotely and adapt to your tools (Jira, Linear, Notion). I’ve supported service businesses, e-commerce and SaaS — from small launches to long-term product development.
