Python Developer | AI & Big Data
I'm studying AI and Big Data. Looking for a Junior Python Developer position — I prefer projects involving data, ML or backends, but interested in any Python-related work.
I build solutions in Python, combining AI & Big Data fundamentals with practical engineering:
- LLM-based assistants (RAG, agents, prompting)
- Data and ML pipelines (ETL, training, monitoring)
- REST APIs and backend systems (FastAPI, async)
- Data analysis and dashboards (pandas, SQL, Streamlit)
- Full-stack applications integrating data with AI modules
- Python (3.10+, async/await, pydantic, pytest)
- SQL (PostgreSQL, JOINs, CTEs, window functions, optimization)
- Machine Learning (scikit-learn, pandas, numpy, embeddings, RAG)
- LLM & GenAI (Azure OpenAI, LangChain, prompt engineering, cost optimization)
- Azure (Azure OpenAI, AI Search, Container Registry, App Service)
- Docker (image building, networking, volumes, docker-compose)
- MLOps (DVC, MLflow registry, model versioning, drift monitoring)
- CI/CD (GitHub Actions, basic automation)
- FastAPI (REST endpoints, Pydantic models, dependency injection, async)
- Streamlit (rapid prototyping, dashboards, data apps)
- React (components, hooks, API integration — supporting)
- Git, PostgreSQL, Jupyter, VS Code, Linux/Bash
Q&A assistant on PDF/CSV documents. Powered by Azure OpenAI (gpt-4o-mini ~$1/1000 queries) and Azure AI Search.

Full-stack data cleaning application. Smart Fix (auto-detect issues), async jobs, before/after diffs.
Stack: Python (backend), React + TypeScript (frontend), async jobs
What I learned: Full-stack thinking, async programming, UI/backend integration

- Python is my main — I prefer it for everything
- Interested in Big Data, data pipelines, analytics
- Learning Azure, but open to AWS/GCP
- Fascinated by LLMs and AI, but also solid backend & data infrastructure
- For every problem I ask: "how do I scale it, automate it, monitor it?"
- Prefer learning by building — more projects, fewer tutorials
