Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

Back-end Python engineer with 3+ years of experience building and maintaining production systems, specializing in REST APIs, async data access, and reliable deployments. I help teams onboard quickly by documenting previously undocumented legacy code and creating end-to-end documentation. I design reliable automation and infrastructure with Docker, CI/CD, and AWS deployment pipelines, and I improve production stability by refactoring legacy code, introducing targeted tests, and implementing fixes for recurring failures. Currently I’m exploring LLM API integrations and AI-powered backend features.…Back-end Python engineer with 3+ years of experience building and maintaining production systems, specializing in REST APIs, async data access, and reliable deployments.

Work Experience

Python Developer (Algorithms & Backend) at Automotive robotic navigation systems

February 1, 2024 - April 1, 2026

Developed and maintained Python-based software for autonomous robotic navigation systems. Designed REST APIs for robot-to-database communication using FastAPI, SQLAlchemy (async), and PostgreSQL. Documented an end-to-end codebase using Diataxis, MkDocs, and Draw.io (including architecture diagrams and inline docstrings) to enable new team members to onboard without tribal knowledge. Refactored legacy code with test-driven/targeted testing using Pytest and test utilities to reduce unpredictable crashes and shift remaining issues to known, traceable problems. Built multi-container applications using Docker and Docker Compose; proposed targeted production fixes to reduce recurring failures and improve reliability. Collaborated daily with international cross-functional teams across software, firmware, hardware, and field engineering.
