Senior Backend Software Engineer at Upwork building Tier-0 IAM services for 60M+ users and creating credential-badge services for partners.

At Upwork, I build and secure Tier-0 identity and access management services for 60M+ users. I created the IAM Core Auditing service and Reputation PCT endpoint, enabling partners including OpenAI, AWS, and Webflow to grant credential badges to freelancers.

I deliver authentication and authorization features across 40+ microservices, including MFA, OAuth 2.0, and RBAC. I maintain 99.99% uptime as an on-call engineer and own more than 100 API endpoints.

At HP Indigo, I designed and built microservices to convert the DFE monolith into a microservices architecture, and led a backend team working across cloud and on-premise services. Earlier, I implemented REST APIs for HP Indigo’s print management platform and helped train eight new team members.

At Cisco, I built and documented REST APIs and wrote automated API tests in Python. I also built web applications for Qwilt and HP, and use tools such as Claude Code, Cursor AI, and GitHub Copilot across development, testing, and documentation.
