Berkin Ozmen's profile on Product Hunt

About

Hi, I’m the CTO at Rierino, where my day-to-day work is focused on building and scaling serious digital infrastructure. This page is a place for my side experiments: small pet projects, vibe-coded prototypes, and things I build mostly out of curiosity. I share them on Product Hunt to test ideas, and see what resonates with other builders. These projects are not my main professional focus, not official Rierino work, and not something I’m actively trying to turn into a company every time. Some may be rough, playful, or intentionally lightweight. A small note for growth agencies, and launch-service providers: I appreciate the hustle, but I’m probably not the right person to pitch. These launches are mostly a hobby, and I’m not looking for promotion, upvotes, PR packages, or campaigns.

Fillament - The form library built for an agent-driven web

One form serves a human and an AI agent — no extra wiring. Forms describe themselves as a contract an agent can read before filling, return validation errors agents can parse and correct like a 422, and expose themselves as in-browser agent tools. Plus everything you'd want from a modern Formik alternative — type-safe field paths, granular re-renders, Zod/Yup/JSON Schema validation, in-browser AI autofill. Twenty-two tree-shakable packages, or grab @fillament/mega for everything at once.

ZeroKeep - Your AI workspace. Your device. Zero cost.

We wanted an AI coding workspace we could use on sensitive projects without routing data through someone else's cloud. So we built one that runs entirely in the browser — local GPU inference, real file access, no backend.
