# Dmitry Shmakov

**Headline:** Professional profile
**Location:** Philadelphia, PA, USA

## About

Dmitry Shmakov is a backend engineer with experience in PostgreSQL, security architecture, agent systems, and ETL and asynchronous streaming\. Dmitry’s strengths include designing secure, scalable backend foundations and carrying complex cross\-stack refactoring through to implementation\. He has designed and implemented a PostgreSQL security layer combining row\-level security, role\-based grants, and column\-level restrictions\. Dmitry has also handled refactoring work that removed database credentials from agent context while preserving security policies during table rebuilds\. In architectural discussions, he has earned team buy\-in for complex decisions through documentation, code examples, and clear technical communication, including when teams initially favored simpler alternatives\. Dmitry is seeking a staff\-level promotion after receiving consistent feedback from multiple managers that there is nothing left to improve at the senior level\. He is motivated by impact, speed, and a grounded culture\.
