Theodor-cosmin Didii is a Staff Software Engineer with 14 years of experience, currently based in Zurich and focused on improving ad quality in Meta’s core auction to drive both revenue and user experience. Over a decade at Meta he rotated through seven roles across build systems, mobile SDKs, commerce, advertiser growth, measurement, and auctions, combining hands-on Android, C++, and Python development with product and people leadership. He helped scale Shops Ads from pilot to a multi-billion dollar product, built bidding SDKs used by thousands of publishers, and shipped features reaching 600M+ FB Lite users. A pragmatic engineer-manager, he led a measurement and attribution team through layoffs and reorganizations while defining long-term measurement strategy through 2027. He’s an active contributor to the Facebook/buck ecosystem—improving the IntelliJ plugin and build UX—bringing a rare mix of deep systems-level engineering and experiment-driven product judgment. Colleagues rely on him to connect dots across teams, domains, and business objectives when ramping into unfamiliar technical territories.
