What I'm looking for

I’m looking for a position where I can combine hands-on technical work with leadership—mentoring teams, driving architectural decisions, and helping align technology with business goals. I want to be part of a company that values innovation, clear communication, and long-term impact.

I am continuously in awe of technology and people's interaction with it. Computer systems have always fascinated me and I wanted to know how they function. This curiosity and passion led me to pursue computer science.

After discovering my passion for programming, I couldn’t get enough. I made websites for friends and family, interned with local businesses, and hired myself as a freelancer.

I am an experienced full-stack web application developer. I am a problem solver and I love to learn.
