• Technical lead of a cross-discipline feature team of eight; spanning engineering, infrastructure, QA, art and design, and production disciplines• Integration lead of several live Riot Games PaaS+SaaS SDK features (e.g. player-to-player chat, multi-user chat, friend/group features, ranked gameplay matchmaking) into the client and server applications (C++) and across multiple platforms (i.e. desktops, mobile, consoles)• Worked closely with the Hosting & Platform team to integrate game server instance discovery, automatic deployment with patchline support, and client application integrations to achieve the vision of an end-to-end connected, multiplayer game with live online services• Implemented foundational data-driven and script-focused game engine feature sets for rapid prototyping by gameplay designers

• Technical lead of engine networking layer with two engineering reports, with support for iOS, Android, Windows/Xbox, Linux, macOS ARM+x86, and PlayStation• Ported C/C++ engine codebase from Windows to Linux to enable remote hosting of the application server; includes support for WSL and Docker for rapid local development iterations that remain accurate to its remote counterparts• Involved in the architecture and implementation of backend services (Java, Go) and cloud deployment hosting platform environments (Terraform, Kubernetes, AWS)• Deployed custom FASTBuild distributed code-caching systems across internal development environments and CI/CD pipelines

• Technical lead for code and engine security (e.g. anti-tamper/anti-intrusion, reproducible deterministic behavior, threat assessments) and player-facing application security (user-generated content loading, network validation, independent security assessments)• Core application server engine contributor in Java (e.g. job scheduling/threading, TCP networking, garbage collection JRE runtime optimization)• Integrated backend services (Java, gRPC, Protobuf) with client application (C#) and internal development workflow pipelines (NodeJS)

• Early engineer involved in growing our player base from 15,000 peak CCU (concurrently connected users) to 60,000+ with over 16 million unique players and three Guinness World Records.• Developed backend infrastructure to manage infrastructure hardware, automatic game server deployment, and real-time game services (e.g. matchmaking, moderation tools). Our bandwidth would exceed petabytes of traffic monthly.• Network Operations team member, ensuring reliable gameplay 24/7 for our world-wide player baseamidst constant DDoS attacks (such as the Mirari botnet attacks of 2016).• Anticheat project lead, responsible for the automated detection of millions of cheaters by reverse-engineering cheat implementations, developing self-learning detection mechanisms, and correlating data sources to analyze and target (previously) undetected and emerging behavior patterns.
