Full-Stack Developer Journey

I'm a Startup Veteran who thrives in fast-paced, high-ownership environments. My journey through three startups shaped me into the versatile full-stack leader I am today.

Starting as a backend developer, I quickly grew into owning entire products—frontend, backend, team management, and delivery. When you're in an early-stage startup with limited resources, you learn to do it all.

Through diverse startup experiences, I've gained invaluable skills inrapid prototyping, wearing multiple hats, and delivering under pressure.
