Crafting high-performance backend systems , scalable APIs, and full-stack applications with clean architecture and a passion for solving complex problems.
I'm Sabarinathan R , a Software Development Engineer at M2P Fintech in Chennai. I graduated with a B.Tech in Computer Science from SRM University. I specialize in backend engineering building robust systems with Java Spring Boot, Node.js, Golang , and designing scalable REST APIs .
Beyond the day job, I'm a LeetCode enthusiast with 250+ problems solved, an open-source contributor , and someone who genuinely enjoys solving hard problems. I believe in clean code, continuous learning, and shipping things that matter.
250+ DSA problems on LeetCode. I thrive on algorithmic challenges and systematic debugging of complex systems.
From idea to production I build and deploy rapidly with clean architecture patterns that scale under pressure.
Writing readable, maintainable, and well-tested code isn't optional it's the baseline for everything I ship.
A curated toolkit built through years of real-world engineering and personal exploration.
A selection of projects that showcase my engineering skills across different domains.
A unique community platform for developers to connect with like-minded peers. Built with the MERN stack for real-time collaboration.
An accessible quiz management app with speech recognition, enabling visually impaired users to participate in quizzes seamlessly.
Real-time chat application built in Android Studio with Firebase backend, enabling seamless user-to-user messaging.
Automated email auto-reply system leveraging Node.js and Google APIs for intelligent mailbox management.
Contributed to a fitness tracking application by developing the real-time chat and video call features. Worked with WebRTC and Socket.io for seamless peer-to-peer communication in a React-based frontend.
Sabari is a quick learner and a reliable team player. His backend engineering skills are impressive, and he consistently delivers clean, well-tested code.
Sabari takes full ownership of his modules and delivers consistently. His ability to debug production issues quickly and mentor interns shows real engineering maturity.
Sabari brought real engineering rigor to our open source projects. His MERN stack contributions were clean, well-documented, and production-ready.
I'm always open to discussing new projects, creative ideas, or opportunities to be part of your vision. Drop me a line and let's connect.
