Summary
👤
Senior🎓
Top SchoolMartín Calabuig is a senior backend engineer with 14 years’ experience designing and operating large-scale distributed systems, currently focusing on high-stakes backend challenges like data pipelines and financial systems. He led backend development for Google’s Digital Garage, migrating and operating a 10M+ user platform and improving observability via Apache Beam, and more recently built usage-based tiered billing with Stripe and Kafka at Keelvar. Comfortable owning architecture decisions, Martín has a strong Python pedigree and a track record of shaving latency and costs—e.g., halving critical endpoint latency and cutting metrics runtimes by 50%. He’s also led teams and hiring, introduced testing and maintainability standards, and untangled large codebases to deliver measurable product gains. Based in Madrid and remote-first, he’s open to senior or staff roles where he can tackle complex backend problems end-to-end. A less obvious strength: he combines hands-on implementation with product-minded features like offline editing and idempotent bulk operations that scale to hundreds of thousands of records.
