What I'm building

Optizads is the AI media buyer and strategist for Google Ads. Its AI agent, Oppy, audits an advertiser's account and writes each change with its evidence.

The advertiser chooses how Oppy works. In Suggest mode it waits for a yes. In Autonomous mode it makes changes on its own, inside the limits they set.

I built the account audit and the Autonomous mode. I keep pushing Oppy to decide like the best media buyer in the room. I also make sure the product stays fast and reliable as more advertisers and agencies join.

How Oppy works

optizads.com/product

Oppy audits the account and writes each change with its evidence. It waits for a yes, or applies what you allowed.

Live since 21 September 2026

optizads.com/changelog

Version 1.0 shipped that day. Every version since is in the changelog, with its date.

Every audit check, listed

optizads.com/audit-checks

Each check Oppy runs on a Google Ads account, named the way the app names it.

Before Optizads

I'm an engineer and a two-time CTO. I have been shipping products for more than 10 years, and leading teams for most of them. At Kawami I started as employee #1 and became CTO, then held the same role at BSMART.

I led frontend teams at Airbus and at Prediko, an AI inventory planning startup that raised more than $6M.

I also co-founded Reqlick, a platform to share and track links, QR codes and files.
