About Santhosh T K

I’m a Full-Stack Developer with a strong focus on backend engineering, currently working at Sify Technologies. Over the past 3+ years, I’ve been building and optimizing applications using Node.js, Express.js, MySQL, and React.js.What excites me most is solving real-world problems through clean, scalable code — whether it’s designing APIs, tuning databases for performance, or making frontend integrations smoother. At Sify, I’ve migrated legacy systems from PHP to Node.js (cutting bugs by 30%), reduced API response times by ~20%, and delivered features end-to-end (backend + frontend) ahead of deadlines.I enjoy collaborating across teams, debugging tough issues, and turning complex requirements into reliable solutions. My goal is to grow as a backend-leaning full-stack engineer, contributing to projects that impact users at scale.When I’m not coding, you’ll find me exploring new frameworks, fine-tuning side projects, or digging into performance optimization challenges.

   I work as a Full-Stack Developer with a strong focus on backend engineering while also contributing to frontend tasks when needed. My role involves designing and integrating REST APIs with React.js, which helped reduce response times by about 20% and improved overall system performance. I migrated core modules from PHP to Node.js, cutting bug frequency by nearly 30% and improving long-term maintainability. Along the way, I implemented JWT authentication and role-based security, optimized MySQL queries to reduce server load, and collaborated closely with frontend and QA teams to deliver complete features faster and more reliably.
