About

Passionate Software Engineer with a strong foundation in C++, system programming, and modern backend development. I enjoy solving complex problems at both low-level (memory, threading, networking) and high-level (system architecture, APIs, services). Skilled in writing efficient, production-grade code — whether it's building high-performance services in C++, designing scalable systems, or debugging tough concurrency issues. I also enjoy working on end-to-end projects involving low-level design (LLD), high-level architecture (HLD), and clean software craftsmanship. Strong understanding of: Data Structures & Algorithms Object-Oriented Design & Design Patterns Operating Systems, Networking, and Multithreading Databases, Cloud Fundamentals, and Microservice Architecture Tech Stack: Languages: C, C++, Java, JavaScript, TypeScript Frameworks: Express.js, Fastify Databases: SQL, MongoDB Messaging: Kafka DevOps: Docker, Kubernetes Cloud: AWS I enjoy working on performance-critical systems, but I’m equally comfortable designing REST APIs, containerizing services, and collaborating on scalable backend infrastructure. With a strong focus on clean design, problem solving, and system-level thinking, I aim to build software that’s robust, maintainable, and impactful.

Optimized multithreaded HTTP server's request handling, reducing memory consumption by >90% for concurrent requests.
Developed modular Content Delivery Service (CDS) DLL and decoupled it from Tally Net Server, enabling flexible integration with multiple server types Improved CDS startup performance by 70% through DLL load time optimization and memory management enhancements Conducted load testing and performance optimization for high-concurrency scenarios (10,000+ simultaneous requests)
Redesigned response handling architecture to eliminate redundant data copying, significantly improving memory efficiency for large file transfers Implemented a high-performance multithreaded HTTP server using Windows IOCP and asynchronous networking APIs, with a custom thread pool designed to efficiently handle millions of concurrent requests.
Added support for memory-mapped file responses, keep-alive connections, and clean shutdown with Windows service fallback.

Designed and implemented a custom spin lock supporting both exclusive (write) and shared (read) locking using 32-bit and 64-bit atomic instructions.
Built for low-overhead synchronization in highly concurrent environments, avoiding kernel-level mutexes.
Developed separate implementations for 32-bit and 64-bit platforms using inline assembly (LOCK CMPXCHG, etc.) for precise control. Developed advanced concurrency control mechanisms using Sync Lock and Threading technologies, creating a secure and reliable authentication system that handles multiple simultaneous users Used to solve the Readers-Writers Problem, ensuring safe concurrent access without starvation or deadlock Integrated and tested the lock with a thread queue system under stress to validate correctness and performance

Completed more than coding 20 assignments on c++,operating system, memory management
Implemented the custom memory allocator which resulted in reduced malloc calls and compared the performance when multiple memory was allocated using CRT allocator and custom allocator. Custom allocator's performance was better than CRT allocator.
