Building products
end to end
Turning ambiguous ideas into shipped products: shaping the direction, building the full stack, and sweating the details that make software feel good to use.
Senior Product Engineer with 14+ years of experience in TypeScript/Go, with an affinity towards developer experience and developer tools. I build APIs and products that help teams ship faster.
Product engineer,
end to end.
I'm Valentin, a product engineer with 14+ years of experience across startups, and I like the whole arc: shaping an idea, building the backend and the frontend, then shipping it to real people.
I went through Techstars with Speakbox, a mental health practice management platform, and I keep a foot in open source. TypeScript is home; I reach for Go when I want a CLI or a tight API, and Python when something just need scripting.

developer toolHookie
Multiplayer webhooks for AI-native development: one URL broadcasts each event to every environment you and your agents work in.
One webhook URL, the same event stream in every developer and agent environment.

Devtools for seeing where React Server Components end and Client Components begin.
The overlay I reach for when the boundary goes invisible.

A CLI Should Do More Than Wrap Your API
Notes from building Hookie: API-shaped commands are useful, but AI-native dev workflows need CLI commands that own the whole task.

Shipping Code Faster Is Not the Bottleneck
Agent-loop discourse sells parallel code output. For solo builders the binding constraint is usually demand, and a useful receipt needs cost, artifact, and a user-visible before/after.

The Interview Gap
The industry says AI agents will write most of the code. Senior engineering interviews still gate on whether you can produce a graph traversal cold in 45 minutes. A checkpoint piece, four months into the job search, on the gap between the two.

Building Incident Memory From Slack and Meet Transcripts
How we built an internal AI post-incident platform around the workflow responders already used: PagerDuty, Slack, Google Meet, structured reports, retrieval, and the tradeoffs that showed up once agent orchestration became production work.
