Rockstar🎓
Top SchoolEd Morley is a Principal Software Engineer with 15 years' experience building reliable platform and developer tooling, currently owning the Heroku Python platform. He combines backend, DevOps and full‑stack expertise—shaping buildpacks, deployment flows and language runtimes while improving caching, CI reliability and error diagnostics at scale. A longtime open-source contributor, he has applied deep knowledge to projects like Django, pip and widely used tooling such as AirBnB’s JS style guide and the deprecated but impactful webpack-chain. Previously he led Treeherder at Mozilla, migrating a terabyte-scale CI service to Heroku/AWS with zero API downtime and helping run hundreds of apps reliably. Colleagues describe him as a pragmatic engineer who moves between code, infrastructure and developer experience, often surfacing clearer error messages and test coverage that save investigation time. Based in Stony Stratford, he pairs platform ownership with hands-on fixes that improve day-to-day developer productivity.
