# Yassine Berrehouma > Senior Software Engineer | Backend • Cloud • Platform Engineering Location: New York, New York, United States Profile: https://flows.cv/yassine I’m a Senior Software Engineer focused on backend systems, cloud engineering, and internal platform development. I enjoy building reliable, large-scale services that help engineering teams move faster and ship with confidence. At JPMorgan Chase, I work on ChaseLane and AppStore — two internal platforms used by hundreds of teams across the company. I’ve owned major backend features in Java/Kotlin, built automation and tooling on AWS, improved CI/CD pipelines, and contributed to multi-region architecture and release workflows. I’m comfortable taking end-to-end ownership: designing APIs, implementing backend logic, building UI flows in React/TypeScript when needed, troubleshooting issues across distributed systems, and collaborating with global engineering, infra, and security teams. I’m always looking to grow — studying cloud architecture, strengthening my knowledge of distributed systems, and building tools that improve developer experience and platform reliability. Open to senior or lead roles in backend engineering, cloud engineering, platform engineering, or internal tools. ## Work Experience ### Senior Software Engineer — Mobile Release Platforms @ JPMorgan Chase & Co.
