Summary
👤
Senior🎓
Top SchoolSergey Zakharchuk is an Application Security Expert with 11 years of experience building secure, high-performance internet infrastructure and client-focused applications. Based in San Jose and currently at Gazprombank, he blends full-stack development with deep security practice, having previously driven security tooling and CI/CD automation at Cisco and Microsoft. Sergey’s background spans large-scale systems—AR/ML prototypes, Kafka/Cassandra pipelines, and hardened UNIX integrations—paired with hands-on work in detection, forensics, and insider-threat monitoring. He favors end-to-end responsibility, routinely bridging dev, ops, and security to deliver auditable, user-centered products. Trained at Bauman MSTU and Kaspersky Academy, he combines formal infosec education with practical system-architecture experience from Mail.Ru and public sector projects. An uncommon strength is his habit of standardizing platform integrations (e.g., VipNet/SoftToken/Django) to free teams for higher-value work.
