About

Backend-focused Software Engineer with experience building scalable, reliable systems and distributed backend services. Currently working on architecting and developing backend components for an AI-driven test automation system, focusing on concurrency, fault tolerance, and intelligent automation. My work involves designing event-driven systems, integrating LLM-based workflows, and improving system reliability through robust error handling and recovery mechanisms. I have hands-on experience building high-performance backend systems using Java, Node.js, and Spring Boot, with a strong focus on system design principles such as caching, rate limiting, asynchronous processing, and microservices architecture. Notable work includes: • Designing a scalable URL shortener with Redis caching, rate limiting, and asynchronous analytics • Engineering a reliable data transfer protocol over UDP with congestion and flow control mechanisms • Building real-time and AI-driven applications with measurable improvements in performance and user engagement Core strengths: • Backend Engineering: Distributed systems, concurrency, API design, microservices • Performance Optimization: Caching (Redis), async processing, efficient data handling • Cloud & DevOps: AWS (EC2, S3, Lambda), Docker, Linux • Problem Solving: Strong foundation in Data Structures & Algorithms (CodeChef 3★, global rank 106) I’m particularly interested in building scalable backend systems and solving complex engineering problems at the intersection of performance, reliability, and system design. Open to opportunities in backend engineering and distributed systems.
