Kweczke

Over a year of hands-on experience with React, Angular, and TypeScript. I build clean, user-friendly interfaces with a strong emphasis on code quality, testing, and maintainability. I leverage AI tools and LLMs to accelerate my learning and problem-solving, using them to deepen my understanding rather than replace it.

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 I've kept the same instinct: look closely at how something works, and care about getting the details right. Outside work I train, and whenever I can I love spending time in the mountains and with my dog.

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

06 - Contact

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.
