Building a cluster optimization algorithm which merges microservices together into threads within a single process to reduce latency and optimize for balanced resource use. The microservices remain isolated and so can be distributed easily as load demands, but will not waste resources when idle.

As a Senior Software Engineer, I built the Node.js profiler from the ground up and improved the performance of AsyncLocalStorage significantly. I also created the diagnostics_channel system and contributed to migrating instrumentations to that pattern, enhancing performance and reliability.

Worked on enhancing Node.js core diagnostics APIs, focusing on async_hooks performance and stability. Major improvements were made to the V8 PromiseHook API and the design of the AsyncLocalStorage feature.

Developed and maintained the Elastic APM Agent for Node.js, contributing to Ruby and Python agents as well. Engaged in community events and speaking engagements to promote the product.

Focused on automation features, including auto-generating client libraries for micro-services and improving service fail-over between cloud storage solutions.

Developed an Android mobile app for realtors that utilized NLP to automate responses to text messages, later transitioning to a PWA for improved stability.

Created a structural transaction tracing agent for Node.js and contributed to the io.js project, enhancing instrumentation for various modules and frameworks.

Developed a micro-service-based backend for a social network in the music industry, implementing real-time updates and notifications.

Designed the communication layer between agents and collectors, improving system stability and performance through a new processing architecture.

Developed a Lua-based game engine and backend systems for social integration and in-app purchases, ensuring cross-platform functionality.

Built a real-time social network for universities, incorporating features like public feeds and private messaging.

Developed an operational transform engine for a real-time web-based productivity suite, enhancing collaborative features.

Created Sayvee, a web service enabling artists to build websites with integrated social features and multimedia capabilities.

Started career by developing various websites with dynamic functionalities, laying the foundation for future software development roles.
