Badar Islam

I am a Senior Full Stack Engineer with over 8 years of experience building fast, reliable web applications from front end to cloud. I design clean, scalable code and smooth user experiences, and I have led projects that improved performance, tightened security, and mentored engineers.

I have delivered cloud-native applications in FinTech and HealthTech, owning architecture, development, testing, and production rollout. I build responsive front ends with React, Next.js and TypeScript, and robust backends with Node.js/Express, Nest.js and Python/Django, deploying services on AWS and implementing CI/CD with Docker and GitHub Actions.

I have experience integrating LLMs, RAG pipelines and Agentic AI to enhance search and automation workflows, implementing real-time features with WebSockets, and enforcing secure authentication using OAuth2 and JWT. I focus on observability, fault isolation, and faster, safer deployments to drive product quality and team productivity.
