What I'm looking for

I'm looking to build scalable backend, full-stack, or AI-powered products where I can contribute to API development, cloud systems, and user-focused software while continuing to grow as an engineer.

I've built scalable backend APIs and full-stack products across fintech, AI, and mentorship platforms.

At Fiserv, I created modern REST APIs with C# and .NET, reducing response times by 35% across fintech platforms. I also tested and validated APIs with Java and SOAP UI for reliable global software deployments.

At Crcle, I engineered AI-powered features with Python, JavaScript, and AWS, improving product performance and user experience by 31%. Previously at Ummah Professionals, I built a React and Firebase platform that increased onboarding capacity by 52% and reduced administrative workload by 48%.

I'm pursuing computer science at Purdue University and contribute to the CS community through workshops and mentorship. My projects include a mentor-mentee scheduling system and an interactive platform tracking large-scale AI infrastructure.
