BACKEND DEVELOPER
Chișinău, Moldova | 5+ years of experience

Python backend developer focused on reliable, predictable product APIs: solid data models, clean interfaces, observability, and automated delivery. I prefer straightforward architecture and reversible changes backed by tests. I work well with frontend, analytics, and infrastructure, framing tasks around outcomes for the business and the team. I’m comfortable owning a feature or subsystem end-to-end, documenting decisions, and handing over context clearly to teammates.

SKILLS
Core: Python (OOP, asyncio, type-hints, concurrency, clean architecture)
Web/APIs: Django (DRF, Ninja), FastAPI, Celery, OpenAPI
Database: SQL, PostgreSQL, Redis, MongoDB
Infra & Cloud: Docker, Nginx, Linux; AWS (EC2, RDS, S3, CloudFront, Lambda)
Ops: CI/CD (GitHub/GitLab), Prometheus/Grafana/Loki, Sentry, E2E & Integration testing
