đź‘‹ Hello!

I am a Software Engineer (SDE-2) at Barclays specializing in DevSecOps, AWS Cloud, and Full-Stack Engineering, focused on building secure, scalable, and production-ready systems. I take ownership from design to deployment—automating infrastructure with IaC, delivering resilient cloud architectures, building clean backend APIs, and shipping reliable CI/CD pipelines. My work supports mission-critical platforms like the Amazon Arrow Card, including multi-region AWS deployments, zero-downtime releases, and CTO-approved strategic solutions.

I enjoy solving high-impact problems by creating internal tools, improving observability, optimizing cloud costs, and enabling teams to ship faster with confidence across AWS, GitLab/Jenkins, FastAPI, Node.js, Spring Boot, and React. I've also won multiple hackathons, where rapid prototyping and execution under pressure strengthened my ability to turn ideas into working products.

Driven by a bias toward action, I continuously build cloud-native, AI-powered projects with a simple philosophy: build it right, ship it fast, and scale it safely.
