About

I am a curious software engineer with several years of experience developing and modernizing high-traffic web and backend platforms in the fintech, automotive, and media sectors. I am comfortable working with diverse technology sets. With each project I develop or adapt, I refine my adaptability. This allows me to tackle complex challenges head-on, overcoming uncertainty and accelerating delivery for distributed teams.

My greatest passion lies in debugging complex problems, where I excel at root cause analysis and creating robust solutions that often have a greater impact than simply adding features.

I find great satisfaction in building fundamental systems that not only scale but also generate a tangible impact. I embrace the challenge of problem-solving, considering bug fixes an integral part of understanding and strengthening systems, and I actively seek new learning opportunities to continuously improve system resilience and my own expertise.
