What I'm looking for

I am looking for a collaborative environment that values innovation and offers opportunities for professional growth.

I am a frontend developer with over 5 years of experience, dedicated to solving problems for my team, business, and clients. My strong technical background allows me to maintain product stability while supporting team growth. I prioritize identifying issues early and selecting the right tools for each situation.

At Sii Poland, I contributed to a large-scale FinTech product, helping the client achieve e4.6B in revenue in 2024. I independently handled complex frontend tasks using React and TypeScript, significantly reducing onboarding time and post-release bugs through effective documentation and test-driven development. My collaborative approach with backend and QA teams ensured that we consistently met deadlines and improved user workflows.

My experience at PROEXE and Cyfrowa Foto further honed my skills in developing high-quality frontend solutions tailored to client needs. I am passionate about performance optimization and improving product stability, and I strive to foster a culture of continuous improvement within my teams.
