- Co-author and maintainer of Uber’s Go Style Guide
- Led and delivered the world’s first self-driving ridesharing launch
- Integrated self-driving cars with Uber’s ridesharing network
- Designed and built the platform to federate all realtime communication between ATG’s self-driving vehicles and Uber’s infrastructure, reducing mobile costs by ~80% and consolidating over a dozen infrastructure services and platforms
- Designed and led the development of platforms for integrating any self-driving vehicle (Uber or otherwise) with the ridesharing network
- Designed and built the platform for realtime remote control of self-driving cars to supplement and train autonomy systems, without humans in the vehicle
- Designed and built autonomy security software and secure vehicle communication protocols
- Led orgwide technical trajectory, drove its adoption, and supported teams during onboarding (e.g. establishing Protobuf as the de facto IDL, gRPC as the overall API strategy, and service infrastructure and architecture in general)
- Led orgwide efforts focused on testing and deploying safety-critical distributed systems, and developed related processes, pipelines, and best practices
- Mentored engineers on technology, impact, trajectory, and growth, many of whom were subsequently promoted or delivered larger initiatives as a result
- Fostered cross-org collaboration and culture through various working groups and roundtables, improving communication, cohesion, and team relationships
- Established and led committees for C++, Go, and Protobuf standards, resulting in near-zero fragmentation, shorter code review cycles, and fewer redesigns and refactors
- Founded and led four core software teams, growing to over 50 engineers in total
- Led the design, implementation, and direction of all systems, such as the core ATS backend, resume processing, and workflow tools
- Managed feature, backend, systems, and infrastructure teams (15+ engineers)
- Mentored colleagues on new technology and best practices
- Established standards & culture around efficiency and security, resulting in sub-second pipeline latency, faster indexing, and <100ms page load times
- Built an autonomous and elastic infrastructure to support all products
- Managed the engineering team, freelancers, and vendors.
- Steered technical direction to align with company goals.
- Led the development of GameZone, as well as the Playwire video player, ad network, and customer portal.
- Rebuilt the Playwire video player from scratch to be modular and fully compliant with all major ad networks, serving 100M+ ad views/month.
- Focused on the overall improvement of ad playback, network integration, availability, and reliability.
- Led the development and direction of product & service infrastructure
- Led the refactor and relaunch of the Rockstar Games Social Club
- Scaled systems for enormous load (e.g. 50M+ concurrent users for GTA V announcement)
- Designed and built the Emblem Editor and in-game integration for Max Payne 3
- Built product sites (GTA V, Max Payne 3, L.A. Noire, Red Dead Redemption, etc)
- Built critical infrastructure, tooling, middleware components, and intranet applications for realtime telemetry, game integration, authentication, administration, research, and more
- Key proponent of reliability, availability, scalability, and security
- Led the company’s technical direction and software adoption
- Managed several independent development teams
- Planned, coordinated, and executed projects on tight deadlines
- Performed a critical role in creative design and planning processes
- Mentored colleagues on new technologies and best practices
- Managed relationships with many high-profile clients, such as Disney, Blue Man Group, Wicked, and more
