What I'm looking for

I am looking for a role that challenges me technically and offers opportunities for growth in a collaborative environment.

I am a versatile backend developer with over 7 years of experience in designing and building scalable systems across Fintech, E-commerce, and Health Tech. My proficiency in JavaScript/TypeScript (Node.js), Python, and Java has enabled me to create robust RESTful APIs, GraphQL services, and microservices architectures. I have a proven track record of delivering secure, efficient, and user-centric solutions in both startup and enterprise environments, and I thrive in remote work settings.

At Chime, I led the backend development for transaction processing systems serving over 15 million users. My efforts in integrating Datadog for system monitoring significantly reduced downtime by 40%. I also collaborated with the fraud team to build a detection API using Python (FastAPI), enhancing our observability pipelines. My previous roles at Favor Delivery and Healthline allowed me to optimize database performance and develop user-facing features that improved engagement and revenue. I am passionate about leveraging technology to create impactful solutions.
