Khizar Ahmad

I’m a full-stack software engineer with 1.5+ years of production experience building scalable APIs, real-time systems, and microservices across Node.js, FastAPI, and React. I’ve delivered end-to-end features solo, from architecture to deployment, with a strong focus on reliability and performance.

I’m especially proud of production-impact work like Stripe flows, WebSocket systems, and event-driven architectures using RabbitMQ and Kafka. I also built RAG-based AI tools, including domain-restricted retrieval with vector storage and context-grounded inference.

In recent work, I deployed a production microservices chat platform on AWS (EC2, RDS, S3, Nginx, Docker) and designed clean service boundaries with an API Gateway, async messaging, and real-time updates. I offloaded heavy async operations to Celery/Redis to improve API responsiveness, while reducing redundant network requests using caching strategies and TanStack Query.

I’m seeking a mid-level role to own features and build at scale—writing maintainable code, integrating securely (JWT, webhooks, Stripe), and shipping systems that perform under real production load.
