I enjoy turning complex business needs into backends that simply work. At Astravue I build a live multi-tenant SaaS platform that stays secure and reliable.

I enjoy turning complex business needs into backends that simply work. Building a live, growing multi-tenant SaaS platform at Astravue taught me how much security, reliability and observability matter in modern backend engineering.

I work closely with product and frontend teams to shape features from idea to release. My goal isn't just to write code, but to solve problems that make the whole product faster, more resilient and easier to maintain.
