Summary
🤩
RockstarJavi Fontan is a Madrid-based software engineer and Go developer with 18 years of technical experience who also works as a licensed farmacéutico. He specializes in back-end systems, contributing to prominent open-source projects like OpenNebula and go-git where he improved packfile decoding, VM drivers, and cloud platform internals. Javi has full-stack chops too, having refactored frontend galleries and editor features in glsl-sandbox while adding pagination, forking and save workflows. He combines practical systems-level optimization (cache-aware decoders, filesystem support) with clear technical writing—authoring and improving OpenNebula documentation. Comfortable navigating both distributed storage/VM concerns and SQL/git integration layers, he brings a pragmatic, detail-oriented approach to performance and correctness. An uncommon blend of healthcare professional and deep systems engineer, he applies multidisciplinary thinking to software problems.
