Martyna
Kweczke

Over a year of hands-on experience in Angular, React and TypeScript. I build clean, user-friendly interfaces, care about code quality more than speed, and use AI agents and LLMs as tools that let me learn faster — not as shortcuts around understanding.

2021 — 2024

Before development

Three years of customer-facing work before the switch: bank employee at Millennium (2023 — 2024), where I walked customers through online and mobile banking, handled escalations and monitored accounts for suspicious activity; and cafeteria worker at Habza Cafe (2021 — 2023), where I also ran the social media accounts. That is where I learned to explain technical things in plain language and stay precise under pressure — most of the job in code review and stakeholder calls, too.

Beyond the code

I came to development from dietetics, and the two have more in common than they look: both are about reading a system carefully before changing anything. Outside work I train, walk in the mountains and look after a very demanding dog — the same routine that keeps me patient with a stubborn bug.

  • Gym and a healthy lifestyle
  • Hiking in the mountains
  • Taking care of my lovely dog

Let's talk.

I'm looking for a junior frontend or full-stack role where I can keep learning from people who care about their craft. Email is the fastest way to reach me.
