Backend engineerChișinău, Moldova[email protected]linkedin.com/in/alexandru-toloaca

Backend engineer with 7+ years in Python, building scalable systems for e-commerce, fintech, industrial operations and AI.

I design Django and FastAPI backends on PostgreSQL, with async processing (Celery, Redis), containerized deployments (Docker) and integrations with payment providers, banks, delivery services and social platforms. I also build LLM-powered products, including RAG pipelines on OpenAI APIs and LangChain.

Before that I worked in BI: T-SQL, SSIS, Power BI, and migrating ~30 databases (up to 2.5 TB) to Google Cloud.
