• Used OpenCode and AI-assisted software engineering to design, implement, refactor, test, and document an end-to-end RAW/SDTM/ADaM pipeline in R for Dr. Falk Pharma (07/2026), including metadata-driven transformations, automated validation rules and QC, traceability, and reproducible clinical outputs.

• Built a private second brain: a local AI agent (Ollama) searches my documents using full-text and vector search (RAG).
• Connected it to the Claude app via MCP with its own OAuth server.
• Private content is filtered out in code before a request reaches Claude (privacy by design).
• Development is agentic: AI agents implement user stories, review agents check them, and I accept and merge them.
• Planned for release as open source.
