Joseph Noumen

I’m a full stack software engineer with approx 3 years of experience building audio and video collaboration platforms at Atlassian (Loom), serving millions of creators and viewers globally. I deliver end-to-end features from React frontends through backend services to production APIs, with a focus on scalable systems and seamless creator experiences.

As a backend engineer, I’m proficient in Node.js, GraphQL, and Java, designing REST and GraphQL APIs that handle millions of requests. I’ve built multilingual caption translation services by architecting the full stack from GraphQL API design through AWS S3 integration to low-latency frontend components, and I optimize database performance, caching strategies, and system reliability under load.

I also take on technical leadership—mentoring engineers, driving architectural decisions, and reducing technical debt to improve reliability. I served as Technical Lead for a critical infrastructure migration from LaunchDarkly to Statsig, coordinating cross-team rollout with backward compatibility and zero downtime, while improving CI/CD pipelines and cutting deployment times roughly in half; I continuously share AI development practices using Cursor and Claude to raise team capability.
