Summary
🤩
Rockstar🎓
Top SchoolMiguel Jiménez is a Staff Software Engineer based in Barcelona with 12 years of experience building high-performance front-end platforms and developer tooling at companies like Stripe, Facebook, Spotify and New Relic. He blends deep native JavaScript and tooling expertise (Webpack/Babel internals, ASTs, V8) with pragmatic backend skills (Node.js, PHP, MySQL) to drive SDKs and modular UI systems that scale across products. At Stripe he built a remote team to standardize interoperable dashboards and common services (observability, i18n, GraphQL connectors), and at New Relic he led efforts that halved 95th-percentile load times through CDN, build and runtime optimizations. A longtime contributor to Jest’s testing infrastructure and to Metro bundler work at Facebook, he pairs strong performance debugging and profiling instincts with a habit of reworking build pipelines and custom tooling to solve systemic problems. Unusually for an engineer of his rank, he began formal studies in medicine, reflecting a curiosity for complex systems beyond software.
