02Story
Story

Getting into software started with a curiosity about how websites worked. After building a few side projects, I landed my first role working on backend systems, which pushed me to learn API design and performance optimization. A particularly challenging project involved migrating a monolithic API to a Next.js-based microservices architecture — it took months but shipped with zero downtime. Now I'm focused on scalable backend development and API design.
