I'm a Full-stack developer passionate about building scalable, real-time web apps using React, Node.js, and AWS. Committed to clean code, intuitive UX, and delivering robust, production-grade solutions.
Hey! I’m Sathyanarayanan V, a passionate full-stack developer who loves building fast, scalable, and real-time web applications. I specialize in React, TypeScript, Node.js, Flask, and AWS, and enjoy working across the full stack to create user-focused, production-grade solutions.
Freelance Work:
Built end-to-end products including an e-commerce platform using the MERN stack with AWS-based CI/CD pipelines, and an event-driven Python trading bot with async queues, PostgreSQL, and a React + TypeScript dashboard.
Previously at Slique Robotics, I was part of the core engineering team, where I lead the development of real-time control systems for robots, integrate WebSockets for teleoperation, and manage scalable cloud infra on AWS.
Previously at Edusphere Solutions:
Delivered 25+ IoT-driven apps and React Native mobile solutions, improving system visibility and operational efficiency for clients.
Previously at Zoho, I developed a full-fledged stock trading platform and optimized backend workflows, laying the foundation for my backend engineering mindset.
Beyond code, I’ve been a student leader — organizing technical talks, mentoring peers, and driving club initiatives in programming and embedded systems.
I thrive in collaborative teams, love solving meaningful problems, and am always exploring new tools to sharpen my craft. Let’s connect and build something impactful together! 🚀
