Skills
What I'm good at
Four things I've done for years, at work and on nights and weekends.
01AI & agents
Multi-agent systems that ship.
Designed multi-agent Gemini systems at Google Cloud. On the side, I run a self-hosted fleet of AI agents and built an app where Gemini reads restaurant menus straight from a photo.
02Data platforms
Data at serious scale.
Four years on an enterprise CDP processing billions of users at ActionIQ, then Cloud SQL, and now BigQuery.
03Product engineering
TypeScript all the way down.
Convinced ActionIQ to adopt TypeScript and led the migration. Led major frontend work at Google Cloud. I still ship full-stack web and React Native apps for fun.
04Leadership
Teams across time zones.
Four years as a Tech Lead Manager, growing a 10+ person team across NYC and Bengaluru and leading the Cloud SQL Enterprise Plus launch. Started as a founder at Tectrify.
Kind words
From people I've worked with
Daniel is incredibly skilled at adapting to new languages and frameworks, picking up Scala, Thrift and TypeScript on his own. He convinced the team to adopt TypeScript as our primary frontend language. His code is clean, thought out, and well crafted.
Harry LedleyEngineering Manager, ActionIQ
Daniel is sharp and has been a quick study, acclimating to a diverse set of web technologies with apparent ease. Among other positive qualities, Daniel is adaptive, communicative, and dependable.

About
Beyond code
I rank everything. I liked it so much I built an app for it. Ted Lasso is a perfect 10. Dune is just okay. I'll defend both.
Off the clock you'll find me at a speakeasy (Raines Law Room is the move), at a sushi counter, baking sourdough, or deep in the longevity rabbit hole. The goal: feel 30 at 60.
Isekai
Solo Leveling is #1. Not up for debate.
Speakeasies
Raines Law Room: a perfect 10.
Travel
