Technical builds and ongoing work focused on models, prompting, and applied AI workflows.

Beta

PDF-to-JSON RAG

Built a local-first Document AI system that converts PDFs into structured JSON, indexes document-aware chunks, and answers multi-document questions with page-level citations. It supports native-text extraction, OCR fallback, quality diagnostics, a web UI and CLI, and reproducible retrieval benchmarks.

It turns messy document collections into inspectable, queryable data while validating extraction and retrieval quality instead of trusting unverified outputs.

ShortsAI outfit planner

Building a weather-aware outfit planner for runners, walkers, and everyday outdoor plans. The app combines live forecast data, activity timing, return-home conditions, and personal comfort feedback into a clear clothing recommendation.

Shows applied AI product engineering: deterministic recommendation logic selects the outfit, while AI explains the already locked result instead of inventing advice.

Pothos - Personal Life OS

Built a local-first Obsidian operating system with 120+ structured Markdown notes, modular context layers, daily/weekly/monthly review loops, and AI-readable vault organization for planning, journaling, and strategic self-management.

Turns raw personal context into review loops, priorities, and behavioral protocols by combining qualitative reflection with Todoist/Rize productivity signals, recovery inputs, and custom OpenCode reflection skills.

Polar Recovery Exporter

Built a small Python tool on top of the Polar AccessLink API that exports daily recovery metrics (sleep, HRV, respiration, ANS) into a clean CSV dataset. The data is used in my AI journaling workflow to analyze how training, sleep, and recovery affect day-to-day performance.

Creates a reliable personal data feed for downstream analysis instead of manual recovery tracking.
