Mykyta Poliakov

I've built and maintained the backend of a B2B AI product at DBB Software, creating configuration interfaces for LLM settings and client access controls.

I maintain and extend legacy Flask services, optimize PostgreSQL queries and indexing strategies, and investigate staging and production issues through AWS CloudWatch and RDS-backed databases. I've also migrated performance-critical authentication logic from Python to Go with feature flags and gRPC communication between services.

I improve delivery quality through unit and E2E testing, GitLab CI pipeline fixes, Docker-based workflows, and code-quality standards with ruff and prettier. I also onboarded and mentored a junior backend developer through architecture explanations, code reviews, and day-to-day support.

For more than three years, I've taught Python through practical, project-based programs covering backend development, data workflows, web development, APIs, and machine learning. Teaching Flask, FastAPI, Django, Pandas, and scikit-learn has strengthened how I explain engineering trade-offs and support learners at different levels.
