● Led architecture design and implementation of NextGen Purchasing, a purchasing platform handling over 30M transactions per day. Increased success rates to 99.999% resulting in extensive increases in user spend. Directed year-long projects to migrate over 10 different teams to the new purchasing platform while avoiding major incidents for virtual products responsible for driving over 90% of all Roblox revenue.

● Coordinated and executed development of the Currency Wallets project responsible for creating an idempotent and highly available ordered ledger acting as the source-of-truth for Roblox’s virtual currency movements totaling up to $50M per day.

● Guided a team to develop the Robux Grant Request tool for automating large-scale currency transfers between developers, support agents, and the CEO resulting in faster iteration and saving employees hours per week.

● Mentored junior engineers and interns on successful Virtual Reporting and Purchasing projects leading to promotions and return offers.

● Performed a full-stack microservice redesign of the Transaction History feature utilizing SQS and Elasticsearch to process 80M financial transactions per day and improve developer insight into key earnings metrics.

● Enacted stronger engineering testing and documentation practices among the Developer Monetization team to increase knowledge sharing and safer deployment and development practices.

● Implemented system for accessing formerly unavailable international payment providers to generate $8M per year.

● Rebuilt the Robux Transactions page with React to follow modern standards and practices allowing for increased engineering velocity.

● Created a system using C# and .NET Core for generating and redeeming Gift Card codes accounting for $10M of revenue per year.

● Compiled large datasets held in SQL databases containing known phishing and security threats targeting university students and administration.

● Developed an automatic threat recognition service using a natural language processing algorithm in Python to scan all incoming emails to university addresses for possible malware or phishing.

● Designed an automated exception-catching system for client-side Electron apps using JavaScript and proxied through hospital firewalls with Nginx, improving response time to system failures by 60%.

● Integrated a Python WSGI server on Windows into a Flask widget using asynchronous workers and multi-threading to serve requests, decreasing client wait times by 40%.

● Developed a JSON webhook between Microsoft Azure and an incident management system (VictorOps) allowing the IT team to monitor the virtual machines 24/7.

● Created a JavaScript source map to de-minify bundled code in Electron apps, letting the IT team debug crashes.
