David Buchan — Junior AI, Automation & Data Analyst

Python · SQL/ETL · LLM APIs (OpenAI, Anthropic, Gemini) · n8n · Playwright · React/TypeScript/Node

I build automation and data systems end-to-end. Career-changer with 13+ years in operations (Lloyds Banking Group call-quality analysis, Windows sysadmin, Deutsche Post, Amazon print production) + BSc (Hons) Computing and IT, Open University 2026. Junior/associate level, honest positioning: no professional software engineering title yet — looking for the first one. Five years in regulated banking make fintech a natural lane.

Open to fully remote roles (Germany or UK). davidbuchan1000@googlemail.com · Site: https://reaver1000.github.io · LinkedIn: https://www.linkedin.com/in/david-a-buchan/ · Hugging Face: https://huggingface.co/reaver1000 (live DuckDB-in-browser SQL demo)

  • Data: Python/pandas, SQL (PostgreSQL, DuckDB), ETL design with tests + CI, e-commerce analytics, finance dashboards
  • Automation: n8n workflows, process automation, QA automation (Playwright, Vitest, Supertest)
