## about

Senior Manager, Data Analytics at Walmart in Bentonville, Arkansas. Five years of turning slow, manual reporting into automated pipelines people can self-serve: SQL, BigQuery, Python, Tableau, and lately LLMs.

Studying for an MS in Computer Science at Georgia Tech (OMSCS) and training for the Dallas Marathon. Ask the castaway for the rest.

## selected work

• walmartAn automated reporting pipeline (BigQuery, Tableau, LLM-written summaries) that grew from 453 market managers to about 1,500 emails a day, cut from 2-3 hours to 45 minutes. Plus a selective-refresh readout framework (45 min to 2-3) and a control-store finder built on statistical similarity.
• carmaxServiceNow and Splunk dashboards that halved incident resolution time and saved each developer about 5 hours a week; a wiki documenting 80+ applications.
• healthcareAt Cancer Study Group, automated reporting that saved 50+ hours a month, and Tableau dashboards that helped grow signed contracts from 1-2 to 10-15 a month.
• this siteA live ASCII ocean and an agentic chatbot, built pairing with Claude Code. How the sea was built · how the castaway thinks · how he's tested.

## how this site works

• stormThe sky is a volumetric storm deck raymarched per character cell and lit from inside by lightning. Branching bolts are drawn as real strokes by the glyph matcher, and the heaving sea below reflects each flash.
• glyphsEach cell is sampled at six points and matched to the character whose shape fits best (after Alex Harri's shape vectors), so edges come out as real strokes. Flat areas use a dithered brightness ramp, and every cell remembers its last glyph so the image doesn't shimmer.
• introThe scene "trains" out of noise like a diffusion model sampling, with a braille loss curve counting down.
• castawayThe little figure on the raft is the bot. He talks to you in a speech bubble and names the bottles you point at. Click him to chat. While he thinks the rain thickens, when he answers lightning strikes, and each streamed word splashes into the sea.
• toolsHe's an agent: ask him to change the sky, call lightning, hand you a post or show you a section, and he does it on the page in front of you.
• tide mapHe doesn't memorize my notes, he searches them: each section is embedded on the server with a small open model (plus keyword matching) and has a spot on a 2D map of that space laid over the sea. Ask him something and you'll see your question drop in and the matching sections surface by name.
• nameMy name is written small in the storm deck as part of the cloud itself. Only the stretch of cloud near each flash catches the light, so most strikes show a fragment, and one right underneath shows it all.
• strikeHold the cursor still and static builds into a crackle around it. Click (or tap) to call lightning down where you point: onto the sea, where it flares and kicks up a ripple, or into the sky. The longer the charge, the brighter the strike.
• botClaude, grounded only in a curated knowledge base about me and told to say "I don't know" when that runs out. Every release is graded on facts, admitting what it doesn't know, declining, and tool use, and a pull request that makes him worse can't merge. Every request is timed and costed on the ops page.
• infraOne container on Cloud Run that scales to zero, with spend capped and requests rate-limited.
