Rockstar🎓
Top SchoolAndrew Grigorev is a security-focused software engineer with 16 years of experience building backend systems, DevOps pipelines, and scalable infrastructure across startups and large companies. He combines deep expertise in Python, Go, C, Linux, cryptography and GIS with hands-on security engineering at FaceApp and prior tech leadership at ngrow.ai and Edadeal. Andrew is an active open-source contributor—most notably improving backend and CI for Iterative's DVC and hardening Flask-Admin—bringing practical fixes to widely used ML and web tooling. He has a track record of architecting high-throughput systems (100+ servers, multi-10TB pipelines), low-latency performance work (Yandex Tank), and production ML deployments involving TensorFlow and RetinaNet. Comfortable working remotely from Limassol, he’s open to relocation with visa sponsorship to Europe or the US and often pairs system-level rigor with research-minded techniques from cryptography and ML. A less obvious strength is his history of improving CI/CD and testing practices that shave deployment time to seconds while raising security and reliability standards.
