Technical deep-dives, lessons learned, and perspectives on distributed systems, cloud architecture, and building software.
I rebuilt Public Radar's recall scorer with tool calling, a strict schema and verbatim evidence, then measured it against 20 hand-labelled recalls. A function that alerts on everything beat it. Here's why, and the eval I built before shipping any of it.
One property in a pom.xml turned six failing tests into BUILD SUCCESS and exit code 0. How I rebuilt Kadra's grader to decide from parsed evidence across vitest, pytest, go test, Maven Surefire and dotnet test, and the places my own fixes were wrong first.
For about eleven months, every Stripe webhook sent to my SaaS hit nginx and bounced. Behind that sat a test-mode signing secret, a column nothing ever wrote, a tier name the database rejected, and prices that disagreed with what Stripe charged. None of it was visible from inside the repo.
Every item in my 3D gym planner rendered as a grey box. Here's how I gave all 63 catalog items a recognizable silhouette without touching hover, compliance tint or raycasting: parts derived from catalog dimensions, merged into one geometry, shipped a whole category at a time.
I went from 'we should make some marketing content' to four AI-generated ads running live on Meta — in one sitting. Here's the pipeline: Google's Nano Banana Pro for the creative, the Marketing API for the campaign, and the gotchas in between.
When I joined the PFM project at EY, the existing authentication system was a security nightmare. Here's how I rebuilt it with Auth0 and integrated it with blockchain smart contracts.
A detailed look at the database optimizations, caching strategies, and frontend improvements that enabled 15x scale without infrastructure changes.
