Hi, I’m Arsalan Nawaz, a Senior Full Stack Developer with 6+ years of experience building scalable web apps and leading cross-functional teams. I enjoy turning complex requirements into robust, maintainable software using Ruby on Rails, JavaScript, React, Flask and FastAPI.
I’m skilled at designing RESTful and GraphQL APIs, optimizing PostgreSQL/MySQL/MongoDB and shipping cloud-based solutions on AWS, Azure and GCP. I also automate deployments with Docker and Kubernetes, implement CI/CD pipelines and mentor engineers to deliver high-performance solutions that reduce costs and accelerate delivery.
