About Me

Passionate Engineering Manager and Front-End Team Lead specializing in front-end development. I actively leverage AI tools such as Cursor, Claude, Whisper, Krisp, and Gemini Pro in my daily workflow to accelerate development, improve code quality, and optimize problem-solving. I thrive in dynamic environments, enjoy tackling new challenges, and continuously expand my skill set. I believe in long-term collaboration and the creation of meaningful digital experiences.

I’m a product-minded developer who values both high standards and human balance. I work best where clarity, systems thinking, and calm execution matter — especially in complex, fast-moving environments.

For the past years, I’ve been combining deep professional focus with an intentionally lived life. During the week, I thrive in demanding projects, long hours, and challenging decisions. On weekends, I slow down. While living and traveling in Japan, those moments of calm often came through walking parts of the Henro pilgrimage — the 88-temple route on Shikoku. That deeply spiritual practice helped me reset, regain perspective, and return to work grounded and focused.

This balance shapes how I work with people and products. I bring reliability under pressure, thoughtful communication, and a long-term mindset. I care about systems that scale, decisions that make sense over time, and teams that feel safe to do great work.

Professionally, I’m driven, disciplined, and accountable. Personally, I’m curious, reflective, and respectful of different cultures and ways of thinking. I believe the best results come from combining strong execution with empathy and inner stability.

If you’re looking for someone who delivers, adapts quickly, and stays calm when things get complex — while still being genuinely human — we’ll work well together.

Beyond engineering, I am a proud father and husband, an avid campervan traveler exploring Europe, a half-marathon runner, and a Japanese language enthusiast.
