About

Engineering-first, design-aware

I'm a software engineer passionate about building scalable web systems with clean code and architectural excellence. My focus is on engineering high-availability systems with atomic synchronization and deterministic data layers.

Currently pursuing B.Tech in Computer Science at DRIEMS University (CGPA 8.1), I've developed expertise in the modern JavaScript ecosystem across frontend and backend. I'm particularly focused on solving complex architectural challenges through microservices, event-driven design, and zero-loss data layer implementations.

My recent work on FinTrack V2 demonstrates my ability to architect scalable systems—implementing RAG pipelines for AI advisory, optimizing throughput by 40%, and ensuring deterministic accounting through BigInt/Integer-cents architecture.

I'm deeply committed to code quality and system optimization, with 350+ DSA problems solved and consistent contributions to competitive programming. I bring strong fundamentals in OS, DBMS, and Computer Networks to every architectural decision.

Always excited to collaborate on projects that push technological boundaries and solve real-world problems with elegant, scalable solutions. Open to remote opportunities and innovative challenges in full-stack engineering.
