Rochester, N.Y. First I built a full Wordle clone, with tile flips, shakes and a 10,656-word list of valid guesses. Then I gave it a cheat code. Turn on Cyborg Mode, the board goes red and an Ask Cyborg button appears. It sends your guesses and tile colors to a Flask endpoint that suggests the next word.

The solver filters the 2,314 possible answers down to the ones consistent with everything you've seen, then picks the guess whose color patterns spread those answers out the most, measured by Shannon entropy. Duplicate letters are the easy thing to get wrong, so feedback is scored in two passes: greens first, then yellows from what's left. The first suggestion is always SALET. I mocked up the UI in Figma before writing any code.

A Local Llama Audits the Company Spending

A team-built spend auditor where a local Llama 3 model checks employee transactions against company policy and flags risks by level.

SU$PEND lets an auditor pick an employee, pull their transactions and run an AI audit against the company spending policy. A local Llama 3 model does the checking, so financial data stays in-house. I built the audit pipeline and the backend.
