Lead a 14-person engineering org in a matrixed, multi-location organization. Grew the team from 4 to 14 as the business invested behind sustained revenue growth. Hired, developed, and promoted multiple engineers into tech-lead roles owning Ingestion/Build and Uploaders with their own reports beneath them. Report progress directly to Senior Engineering Leadership, VP of Engineering, and the divisional CTO.

Tech-led the Brand Networks Segment Builder ground-up rewrite under a 3-week existential deadline. Rewrote the entire CDP-ETL pipeline to introduce sharding and zero-spill builds; scaled the customer-facing discovery UI from ~10–50M aliases (minute latency) to 63B aliases (~15s response) via the Mart Device List / Mart Segment List split. Real-time-shaped customer-facing UI at marketplace scale.

Authored the Tapad Test Framework, bid-request replay tool, and HTTP/SFTP mock servers adopted across engineering. The bid-request replay tool let engineers reproduce live RTB traffic for offline testing—core infrastructure for a real-time bidder team and the kind of developer-productivity work this role calls out.

Shipped Tapad’s first production Spark ML pipeline (Telenor pre-paid/post-paid classification on Dataproc). Partnered directly with applied data scientists on schema design, feature engineering, and live-site productionization.

Founded Tapad’s Attributes domain as the original architect. Designed the company’s first unified, config-driven pipeline (Business Logic Component, Build Initializer, data catalog + Firestore metadata). New attributes added via configuration—a platform other teams built on.

Performance and reliability engineering at Microsoft scale on cloud-security and headless cable-box products. Built test automation in C++/C# for high-throughput backend services with low-latency requirements—the foundational discipline for revenue-critical real-time systems.

Later tenure on Office for iPad and Mac. Owned ribbon-UI work on iOS, plus SSO and legacy-auth integration testing across the Office suite.

Earlier: Co-founder at Nullptrstudios LLC between Microsoft and Tapad (Dec 2014 – Jul 2015): two-person mobile-games studio, shipped multiple titles on iOS, Android, and Windows Phone using Unity3D with Firebase Authentication and Firestore in production.
