What I'm looking for

I'm looking to build and improve scalable microservices, APIs, cloud infrastructure, and developer tooling, especially for complex products where I can contribute to architecture, deployment patterns, and cross-team delivery.

At PayPal, I build and maintain Java and Python APIs for cryptocurrency initiatives across PayPal and Venmo, including Cryptocurrency Transfers, multi-chain transfers, and PYUSD. I’ve developed Spring Boot microservices from scratch, implemented REST and GraphQL APIs, and contributed to API design and documentation.

I also maintain PayPal Crypto web experiences in React, support AWS, Kubernetes, and CDK automation, and help define internal tools, patterns, and guidelines for teams building and deploying microservices.

Previously, I built personalized trip-planning services at Itini, managed its Google Kubernetes Engine infrastructure and DevOps processes, and developed smart traffic-light monitoring systems at Seebot using Java, Spring Boot, Python, Angular, Flutter, and MySQL.
