React and TypeScript interfaces
Build application screens and user flows, connect them to APIs, and work on the behaviour and structure of an existing frontend.
Web development for your business.
I work with businesses on web applications using React, TypeScript, and Node.js.
Based in the EU (Poland).
Build a feature, improve an existing application, or work through a technical problem. I take responsibility for the engineering work we agree on, from understanding the problem to implementing and reviewing the changes.

Where I can help
A specific feature or a broader application: we start with what your users and business need, then agree on the work.
Node.js application work
Develop backend features, API endpoints, and integrations that connect the interface with your application’s data and services.
Existing applications
Investigate a bug or performance bottleneck, review the relevant code, and explain the trade-offs before making changes.
Selected engineering work
My own product and open-source work show how I approach problems beyond a single technology stack.
Personal product
BugEater
Gamified learning for QA, Business Analysis, and Project Management.
Learners follow guided trails and practise in real-world sandboxes. I built this EdTech product from scratch: a Java/Quarkus backend, an htmx and TypeScript frontend, and Supabase for authentication and PostgreSQL.
The engineering decisions include investigating slow page loads. I wrote about the bottlenecks I found and what changed when I fixed them.
Open source
voca_rs
Unicode string utilities for Rust.
I authored voca_rs, a library used in Brave Browser. It brings string manipulation tools to Rust with Unicode support.

Working together
Tell me about the application, the problem, and the people who use it. We’ll discuss the scope, terms, and next steps by email before starting. During the work, I explain the technical decisions and raise questions that affect what we’ve agreed to deliver.
Tell me about your project.
What are you building, and where do you need help? A few lines and any useful context are enough to start the conversation.
