Now

Building end-to-end intelligent systems and automation platforms in Python and C#/.NET. Available for freelance engagements and full-time remote roles.

What I build

  • Production LLM agents. Multi-model, tool-using, with the guardrails that turn a demo into something you can deploy: loop bounds, structured tool errors, observability, guarded retries.
  • Corporate integrations. Microsoft Graph, Microsoft 365 tenant work, Teams bots, SharePoint pipelines, Google Workspace. The awkward corners the SDKs leave to you.
  • Executive document generation. Programmatic PPT with custom render engines, DOCX with real styles, PDF, OCR pipelines. Output that looks like a designer touched it.
  • Static analysis for spreadsheets. Rule-based auditors that find silent bugs in workbooks people bet payroll on.
