About

Hi, I’m Sandra Santhosh, a results-driven Full Stack Developer with 5+ years of experience designing, building, and deploying scalable web applications. I specialize in C#/.NET on the backend and React/Next.js on the frontend, delivering robust RESTful APIs and responsive user interfaces that perform well under load. I’m comfortable in Agile environments and enjoy collaborating with cross-functional teams to align tech solutions with business goals.

I’m proficient with cloud services (AWS), CI/CD pipelines, RBAC, OAuth2, and database technologies like SQL Server, MySQL, and MongoDB. I love writing clean, maintainable code, automating repetitive tasks, and continuously learning new tools — including AI-assisted development aids — to improve productivity and software quality.
