Awais Hassan

I’m a Senior Full Stack Engineer with 7+ years of experience specializing in MEAN and MERN stack development. I deliver scalable web applications and high-performance APIs using Node.js, Express.js, React, and Angular. I focus on system design and database performance optimization—using indexing strategies, query tuning, and aggregation pipelines to reduce latency and improve throughput. I also build secure, production-ready RESTful APIs and backend services with NestJS, while integrating authentication/authorization and robust API integrations. I’ve led technical initiatives through design discussions, code reviews, and engineering best practices, and I mentor engineers to improve maintainability and team productivity. In distributed remote environments, I ship end-to-end solutions using CI/CD, automated testing, and containerized deployments with Docker and cloud infrastructure (AWS/Linux). Beyond core full-stack work, I integrate AI-powered features into SaaS platforms—implementing LLM integrations, RAG (Retrieval-Augmented Generation), prompt engineering, and conversational automation workflows. I’ve built AI orchestration services with streaming responses and token optimization, and automated AI workflows using n8n and server-side agents.
