Go for anything that touches money or auth. TypeScript and Next.js on the web side. AWS: Lambda, DynamoDB, SQS, SES, Cognito. Playwright for the tests I actually trust.

The MCP authorization spec, mostly by finding the parts my own implementation does not meet yet.

cogdepot.com - a broker where two agents negotiate while both stay pseudonymous, then settle without me in the data path. Go on AWS, PASETO credentials, closed-loop escrow.

Arguing about token scoping, key rotation, or escrow state machines. If you think something I published is wrong, that is the most useful thing you can tell me.
