What I'm looking for

I’m looking for a remote or Bucharest-based role where I can work mainly with Python, backend systems, APIs, data pipelines, or AI/ML. I’d like to join a team where I can contribute to real products, take on more responsibility over time, and keep improving technically. I’m open to Python Backend, AI/ML, and Data Engineering roles

I’m a Python Backend Engineer with 2+ years of freelance experience, mainly working with FastAPI, PostgreSQL, REST APIs, data pipelines, Docker, and cloud tools. I’ve built backend systems for inventory analytics, industrial monitoring, maintenance workflows, and external API integrations.

I also have a strong interest in AI/ML and have worked with scikit-learn, TensorFlow/Keras, forecasting, anomaly detection, computer vision, RAG, embeddings, and model-serving APIs. One of my ML projects used a 500k-row sensor dataset and achieved 0.9959 accuracy and 0.97 F1 on the failure class.

I’m currently completing a Master’s degree in Automation and Computer-Integrated Technologies. I’m mainly looking for Python backend, AI/ML, or data-focused roles where I can build real systems, work with APIs and data, and keep growing technically.
