Dmitry Ehrlich is a seasoned software engineer with 14 years of experience building robust backend systems, embedded Android/AOSP solutions, and desktop applications across C++, Python and modern async Python stacks. He has driven CI/CD, testing and observability initiatives at enterprise scale (Jenkins, ELK, Docker) and prototyped WebRTC meeting apps and in-car integrations for Mercedes-Benz. An active open-source maintainer on the widely used aiohttp project, he focuses on HTTP parsing, reliability fixes and improved typing for asyncio-based servers and clients. Comfortable both leading small teams and diving into low-level protocol code, he blends a physics/mathematics foundation with pragmatic engineering to tame network complexity and flaky tests. Notably, he has repeatedly migrated legacy builds to modern systems (CMake) and implemented FSM-based refactors to simplify and unit-test networking logic.
