About

Backend engineer with a focus on building cloud infrastructure and backend systems that perform reliably at scale. Currently pursuing my MS in Software Engineering at Arizona State University with a 4.0 GPA, graduating May 2026. My recent work has been at the intersection of backend systems and AI. At Vosyn, I built recommendation APIs that improved click-through rates, fine-tuned LLMs for content tagging, and redesigned database schemas to reduce latency. Before that, at WINspect Technologies, I worked on REST APIs, Redis caching layers, and automated testing for time-synchronization systems. On the projects side, I won the Claude Developer Tools track at HackASU 2025 for CrodeX, an AI-powered framework migration tool. I have also built autoscaling face recognition pipelines on AWS using EC2, Lambda, S3, and SQS, as well as edge computing systems with IoT Greengrass for low-latency inference on resource-constrained devices. I enjoy working on problems that involve system design, performance optimization, and figuring out how to make things scale without falling apart. Comfortable working with Java, Python, Spring Boot, Django, PostgreSQL, Redis, Docker, and various AWS services. Looking for full-time backend or infrastructure engineering roles starting May 2026. Let’s connect!
