C++ Developer | High-Performance Computing (HPC) | Algorithmic Problem Solver

Welcome to my digital workspace. I am a pre-final year Engineering undergraduate at NIT Durgapur with a deep background in competitive programming (Indian National Olympiad in Informatics INOI 2023 Bronze Medalist 🥉). I focus heavily on low-latency systems engineering and actively contribute to large-scale open-source codebases, specializing in parallel C++ algorithms while also resolving complex infrastructure challenges in enterprise ecosystems.

• High-Performance Computing: Building distributed, parallel algorithms and non-uniform segmentation infrastructure for STE||AR Group (HPX).
• Low-Latency Systems: Engineering C++17/C++20 data structures, including wait-free SPSC ring buffers and high-performance limit order book engines.
• Enterprise Open Source: Diagnosing and resolving complex routing, tracking, and CLI issues across production repositories like Cal.com and the Google Gemini CLI.

• HPX (C++ Standard Parallelism):
  • Implemented and merged the segmented hpx::equal parallel algorithm for distributed memory vectors.
  • Engineered the reduction logic and infrastructure for the segmented hpx::mismatch parallel algorithm.
• Micromatch: Engineered a C++17 Limit Order Book engine with sub-100ns matching latency and O(1) order cancellation.
• AtomicQueue: Architecting a wait-free Single-Producer Single-Consumer (SPSC) ring buffer using C++20 atomics.
