Summary
🤩
Rockstar🎓
Top SchoolJaroslav Šmolík is a VP of Engineering and backend-focused leader with nine years of experience designing resilient APIs, data pipelines, and payment systems from Prague. He blends hands-on engineering—shipping distributed queue architectures, rate limiters validated under heavy concurrency, and SQL/BigQuery performance tuning—with operational ownership of SOC2, PCI DSS, and infra compliance. Jaroslav excels at turning messy production problems into repeatable systems (e.g., migrating monolith cron jobs to Cloud Tasks and rebuilding SMS and notification stacks for bilingual, DB-driven rendering). He hires and scales teams thoughtfully, codifying onboarding, tech-debt standards, and company-wide conventions while enabling non-technical teams with self-service analytics. Known for a culture of open learning and "TIL"/failure-sharing, he pairs Clean/Hexagonal architecture advocacy with pragmatic delivery.
