About Me

From Gears to Code

With over a decade of experience maintaining critical systems in aviation and pharmaceuticals, I've mastered the art of mechanical problem-solving. Now, as an aspiring software developer, I'm translating that expertise into software engineering. My journey from gears to code gives me a unique perspective on building reliable systems — whether physical or digital.

My maintenance background is my superpower. Those 10+ years taught me systematic debugging, precision documentation, and how to thrive under pressure — skills that directly translate into writing clean, maintainable code. I'm especially passionate about building tools that solve real-world problems.

My next mission? To build real-world, problem-solving projects that merge my mechanical roots with modern code. The future of engineering is interdisciplinary — and I’m committed to speaking both of its critical languages: machinery and software.
