CSE Undergrad at VNIT Nagpur building high-throughput low-latency systems, lock-free concurrent structures in modern C++20, and resilient distributed architectures. Open-source contributor to QuantLib. Zero third-party analytics — telemetry rendered natively by this repo.


About Me

  • CSE Undergrad at VNIT Nagpur
  • Core Interests: Low-latency systems, lock-free concurrency, high-performance C++20, and distributed architectures.
  • Quant & Systems Research: Order matching, SPSC lock-free queues, memory models, cache-line alignment, and cross-currency arbitrage engines.
  • Open Source: Contributor to QuantLib — the premier quantitative finance C++ library (yield curve exponential spline fitting & interest rate coupons).
  • Passionate about deep algorithmic problem solving and writing clean, cache-friendly, production-grade code.
