About Me

Hi, I’m Varun Mantri — a final-year B.Tech student at IIIT Sri City with a strong foundation in full-stack development and system design. I’m passionate about building real-world solutions that are fast, scalable, and user-centric.

My work spans automation systems, custom in-memory data stores, and some open-source contributions, all driven by curiosity and a deep desire to understand how large-scale systems are built and optimized at top tech companies. I actively explore web technologies, low-level system internals, and developer tooling.

Outside of development, I enjoy solving algorithmic problems, mentoring peers, and engaging with the developer community. Always open to learning, collaborating, and growing through impactful work.
