Summary

Rockstar🎓
Top SchoolIvan Chernov is a pragmatic technology leader and hands-on CTO with 12 years of experience building and scaling web platforms from Moscow. He has led teams from 20 to ~100 engineers, reshaped orgs toward cross-functional delivery, and delivered measurable outcomes like 40% reduced time-to-market and an ~8x scalable search RPC by designing caching and logging storage solutions. Equally comfortable in strategic M&A audits and in the codebase, he frequently rolls up his sleeves—migrating services to Kubernetes, implementing storage for search logs (Postgres+S3), and improving cross-platform stability in open-source projects like Lektor and django-tinymce. A polyglot developer with a soft spot for Python and Node.js, Ivan combines rigorous test automation and CI practices with product-minded engineering and rapid learning (Udacity Full Stack Nanodegree completed projects within a month). Off the clock he’s a comic-book fan and cyclist, traits that reflect his curiosity and endurance in tackling long-term technical challenges.
