Summary
🤩
Rockstar🎓
Top SchoolHeitor Neiva is a Staff Release Engineer with a decade of experience automating build and release pipelines, currently shaping release practices at Mozilla from Kamloops, BC. He has driven deployment and beetmover automation for Fenix (Firefox for Android) and implemented build-format and incremental update tooling across gecko-dev, blending deep release engineering with DevOps craftsmanship. Previously he led CI/CD, cloud automation and systems architecture at BCLC and built full-stack and DevOps solutions for startups using AWS, Java/Kotlin, Python and modern front-end stacks. Known for pragmatic improvements to complex release workflows, he pairs hands-on scripting and configuration work with a systems-level view that reduces friction across teams. An unusual strength is his breadth: he moves comfortably between low-level packaging (XZ, update tooling) and higher-level orchestration (workers, buckets, CI pipelines).
