Faizan Ahmed

I'm a Backend Engineer with nearly 3 years of experience building scalable, high-performance APIs using Django, Django Ninja, and GraphQL. My main focus is backend development — designing RESTful architectures, optimizing database performance, and ensuring clean, maintainable code. I also collaborate with DevOps team to debug production-level bugs involving EC2, EBS, S3, RDS, ASG, ELB, AWS CloudFormation, IAM and Elasticache.

In addition to backend work, I'm comfortable working on frontend tasks such as implementing UI fixes, API integrations, building dashboards and occasionally debugging Flutter mobile app issues. Passionate about clean architecture, API performance, and cross-team collaboration to deliver reliable, production-ready systems.
