software_engineer · product_builderFinal-year Information Systems student at Universitas Indonesia. I focus on building full-stack products, from architecture to deployment. My background spans both engineering and design, which means I can own a feature end-to-end: system design, backend APIs, frontend components, and UX decisions. I've shipped microservices, hackathon products, and internal tools. Always open to new challenges and interesting engineering problems.
