I am a Software Engineer at Cognivac, working as a Full Stack Developer with hands on experience building scalable, production grade web and mobile applications. Alongside my full time role, I also work as a freelance developer, delivering reliable, business focused software solutions for clients.

On the backend, I work extensively with Java Spring Boot and Python FastAPI to design secure REST APIs, implement authentication and authorization, and build scalable backend systems. I have strong experience with PostgreSQL, MySQL, and MongoDB, and regularly use Supabase and Firebase for authentication, real time data, and cloud services.
