About

Waleed focuses on cloud-native backend system architecture for SaaS products as a Senior Software Engineer.

He handles requirement breakdown with product partners, cross-domain integrations, and migration work where legacy billing or workflows must be replaced safely. His scope often includes infrastructure planning with AWS, Terraform, Docker and CI/CD, plus reliability targets like near-constant uptime, though the path there is rarely neat.

He has supported React.js with TypeScript UIs, and used Flask, MySQL, Redis, SQLAlchemy, Celery, Apache Kafka, Kubernetes, JWT and multithreaded programming when needed.
