Summary
🤩
Rockstar🎓
Top SchoolAlexander Leibzon is a technical consultant and infrastructure-focused backend engineer with 11 years of experience designing and operating distributed systems across startups and larger tech firms from Israel. He blends hands-on backend development (notably contributing bug fixes and feature enhancements to the popular open-source Redash project, including Google Sheets integration and charting fixes) with architecture and data infrastructure consulting for companies like Playtika, Outbrain and several gaming and security startups. Comfortable across the full data stack—Hadoop/EMR, Redshift, PostgreSQL—and cloud infrastructure, he routinely helps teams turn analytics platforms and pipelines into reliable production services. His background in physics and computer science underpins a methodical approach to performance and reliability, while a hardware hobbyist streak informs pragmatic, low-level troubleshooting. Colleagues rely on him for pragmatic architectural guidance and for translating complex operational requirements into maintainable engineering outcomes.
