Tech Lead | Building Scalable AI & Distributed Systems | LLM, RAG, Microservices @ Scale | FastAPI • AWS • Azure | 7+ YOE · Noida, Uttar Pradesh, India
Tech Lead and Senior Backend Engineer with 7+ years of experience designing and scaling distributed systems, backend platforms, and AI-powered services for production-grade SaaS products. I specialize in building high-throughput, fault-tolerant systems using microservices and event-driven architectures. My work focuses on solving complex backend challenges around scalability, performance, and reliability, while integrating modern AI capabilities into real-world systems. In my current role, I own backend architecture and delivery for multi-tenant platforms, where I have: • Architected and scaled 9+ microservices using event-driven design (RabbitMQ, Celery), reducing inter-service latency by ~30% • Built LLM-powered systems using RAG and GPT-4o to enable automated, context-aware insights at scale • Designed asynchronous processing pipelines to decouple heavy workloads from APIs, ensuring system stability under load • Improved system performance by reducing P95 latency by 25% across production services • Implemented secure multi-cloud storage and access patterns across AWS, Azure, and GCP I have led and mentored teams of 10+ engineers, driving system design, code quality, and end-to-end delivery for complex backend systems. Core expertise: Distributed Systems, System Design, Microservices Architecture, Event-Driven Systems, Backend Performance Optimization, AI/LLM Integration (RAG) Tech stack: Python, FastAPI, Node.js, RabbitMQ, Celery, Kafka (POC), PostgreSQL, MongoDB, Redis, Docker, AWS, Azure, GCP, Vault, Keycloak I am particularly interested in building and scaling backend platforms and AI-driven systems that operate reliably at high scale.
