Back to original languageAbout Behdad
I help teams build robust Python backends that run reliably under load.
As a backend developer with 4 years of experience, I specialize inPython, FastAPI, Django, and SQLAlchemy**. In my current full-time role, I am responsible for over **80 REST endpointsas well as cron jobs that process more than100,000 data recordsdaily. Through targeted refactoring, I was able to reduce the execution time of critical jobs by40%and increase test coverage with Pytest to **80%**.
Since 2024, I have been supplementing my backend work with applied **AI and LLM development**: RAG systems with vector databases, LLM tools (search, summarization), chat services with prompt engineering and context management. My focus is on AI features that are cleanly integrated into productive backends — not isolated demos.
Services I typically undertake:
- Design and development of REST APIs (FastAPI, Django)
- Integration of LLM functionality into existing systems
- Automation of business processes (cron jobs, workflows)
- Performance optimization and refactoring of legacy code
- Database modeling and CRUD layers (SQLAlchemy, Pydantic)
Additional focus: Construction & BIM
With an M.Sc. in Civil Engineering (HTW Berlin)and practical experience withRevit and PyRevit(Master's thesis, Arcadis), I am particularly interesting to AEC and construction companies looking for a developer with domain understanding. Specifically:PyRevit automations and plugins,BIM data pipelines (extraction from Revit models, APIs), and backend development for software products in the construction and architecture sectors.
Stack: Python, FastAPI, Django, SQLAlchemy, Pydantic, Pytest, PyTorch, Docker, Kubernetes, Git & CI/CD, MSSQL, REST, OpenAI/Llama/Gemini, Revit, PyRevit.
Based in Berlin — preferably remote.
