Backend & Systems Engineer — I build multithreaded C++ services, low-latency pipelines, and backend systems that have to stay correct, fast, and reliable under real production load.

Currently building real-time trading and risk infrastructure at ThunderStrike Quant Research LLP, where systems fail expensively if they don't perform.

• High-performance C++ backends — order handling, market-data ingestion, and execution flows
• Low-latency event-driven systems with multithreading, concurrency, and lock-free patterns
• Redis / MySQL pipelines for real-time analytics and distributed caching
• Python services for risk checks, exposure tracking, and internal tooling
• Refactoring legacy components into clean, modular, testable systems

• Languages: C++ (STL, Boost, multithreading, lock-free patterns), Python, SQL
• Backend & Systems: low-latency design, event-driven architecture, concurrency, distributed caching, REST APIs
• Data: Redis, MySQL, real-time data flows
• Systems / Tooling: Linux, gdb, CMake/Makefiles, Docker, Git, system-level programming
• Domain: market data, FIX protocol, real-time risk

• Built multiple full-stack projects (Next.js, React, Node.js, MongoDB)
• Strong fundamentals in algorithms & competitive programming — LeetCode Knight (1887, Top 8%), active on Codeforces
