About
I love challenges. I think big-picture. And, although I have a deep appreciation for elegant solutions, I have a knack at getting things to work.
I also love people. In a break from my work in technology, I spent two years in the Philippines working with children impacted by HIV/AIDS. When working on projects, I am motivated most by my team members. Ultimately, it is the people in my life that drive me and inspire me.
Featured Projects
GitSavvy
Full git and GitHub integration with Sublime Text. I created GitSavvy in 2015 and led its development through 2017; it is now maintained by the community, and still in heavy use today. Provides dashboards to view and manipulate the index, branches, tags, and to rebase. Other features include showing per-file changes inline and staging individual hunks or lines, many ways to view commit history, cherry-picking, and branch diffing.
Lightning Web Components
Salesforce's open-source framework for building fast, scalable applications with standards-compliant web components. As a core maintainer of the LWC engine and compiler, I architected Salesforce's server-side-rendering offering — including a specialized compiler and runtime that improved SSR speeds by 5-40x — and championed developer-experience initiatives impacting millions of Salesforce developers.
Walmart.com Checkout
Single-page application, serving millions of users daily. I designed the core flow component that maps purchase contract state to application state. I also worked on cross-track error handling and several UI features, first with Backbone and later with React.
Earlier Open Source
Freactal — a composable state-management library for React, featuring Promise-based composable effects and hierarchical state that mirrors the component hierarchy.
Rapscallion — an asynchronous React VirtualDOM renderer for the server, with a streaming interface and a component-caching API.
Interlock — a Git-inspired bundler and build pipeline for the modern web, built on Babel.
Drydock — a stateful, interactive mocking framework for offline development and end-to-end test automation, later adopted organization-wide at Walmart.
Talks and Presentations
Defending the Supply Chain: Building a Real-Time Package Firewall
Malicious packages increasingly enter the ecosystem through compromised maintainer accounts of high-profile open-source projects. In this talk at BSides Seattle 2026, I walked through how Socket Firewall wraps package managers and blocks malicious and typosquatted packages at install time — and the lessons learned shipping a real-time package firewall that developers actually want to use.
Embrace HTTP/2 Server Push
HTTP/2 Server Push is an exciting new technology that you can use today. In this talk, I provided an overview of the history of the web, and the challenges that were addressed at each stage of its development, in the form of a child's narrative.
Additionally, it showed the benefits that HTTP/2 can provide to your SPA - especially those of its server push feature - and introduced Interlock as a way to embrace those changes.
Work History
Staff Software Engineer, Socket
Socket Firewall
I built Socket Firewall, which blocks malicious and typosquatted packages at install time, via an ephemeral HTTP proxy. I introduced both the free and the Enterprise offerings before moving on to other projects.
Lead Member of Technical Staff, Salesforce
Lightning Web Components
As a core maintainer of the open-source Lightning Web Components engine and compiler, I led development of Salesforce's server-side-rendering offering — architecting a specialized compiler and runtime that improved SSR speeds by 5-40x, and subsequently guiding engineers across the company as thousands of components were made ready for non-browser environments.
I led the engineering effort for a generative-AI "compiler" that transforms pro-code artifacts into other pro-code artifacts — defining the agentic architecture and establishing patterns for structured interactions with LLMs, while serving as tech lead for roughly twenty engineers.
I championed developer-experience initiatives impacting millions of Salesforce developers, including a new reactivity mechanism for LWC, state-management solutions, component development playgrounds and toolkits, and JavaScript-like expressions in LWC templates.
I also supported the growth of my fellow engineers through internal tech talks, design consultations, pair programming, and direct mentorship.
Software Engineer, Vercel
Next.js
On the core Next.js team, I drove performance improvements to Webpack and the wider compilation pipeline through production instrumentation, trace- and sample-based profiling, and manual analysis — improving fast-refresh development responsiveness by over 5x for hundreds of thousands of active users.
Through proofs-of-concept and experimentation, I laid the groundwork for targeted optimization of compilation and bundling hot paths by rewriting performance-critical operations in Rust — work that later evolved into Turbopack.
Senior Program Manager, Microsoft
Edge Browser
I established the Edge browser's open-source strategy, balancing internal business needs while engaging with the Chromium and other OSS communities.
I architected and led the engineering effort for Microsoft's first cloud-native performance lab, and developed an HTTP(S) MITM proxy for deterministic recording, postprocessing, and playback of diverse web content — with support for original response timings, WebSockets, streaming content, and HTTP SSE.
Representing Edge and Microsoft with TC39 and the W3C Performance Working Group, I edited and collaborated on web-platform specifications.
Senior Software Engineer, Formidable
Walmart.com Core Web
While a member of Core Web, I architected a new build and application infrastructure for Walmart.com and Walmart's global online properties. As part of that effort, I created a hybrid infrastructure that bridged legacy and next-generation application infrastructures. This allowed individual teams to adopt new technologies incrementally.
Following the successes of mock-first development in the Checkout team, the mocking framework I created saw increased adoption with other tracks and the organization at large. After a company-wide re-focus on end-to-end functional testing, I began supporting mocking efforts in a more formal capacity, including the development of tools that generate mocks from captured network data.
As a member of the React Working Group, I helped to define build and application architectural standards, promoted best-practices for emerging tools and technologies, and supported the formation of the new Walmart Labs React ecosystem.
Microsoft Office 365
I spent much of my time on mentorship and training, focusing on JavaScript frontend best practices, as well as React/Flux design patterns. Some of these best practices were later enforced using static analysis and test coverage requirements.
Software Engineer, Formidable
As a member of Walmart.com's Checkout Team, I designed the core flow of Walmart's checkout single-page application, serving millions of daily visitors and representing tens of millions in daily revenue.
Once we reached a stable point in the Checkout development life-cycle, I was tasked with extending the application to accommodate Walmart's new ShippingPass member features.
After continued difficulties relying on external dependencies, I created a flexible mocking framework for easy, offline development. It also served as a foundation for end-to-end automated functional testing. This mocking framework was later adopted organization-wide.
Outside of my Walmart work, I served as an instructor for our Formidable JavaScript training sessions.
Programming Intern, SpectraLux Corporation
Developed tools to parse and transform thousands of G-code programs standardizing into formatted, commented, simplified G-code programs. Included edge-cases for auto-generated and 20-year-old hand-written programs of several G-code dialects.
Missionary and Volunteer, Manila Philippines
I worked and built relationships with vulnerable children impacted by HIV and tuberculosis. While there, I also collaborated on commemorative videos and dramas, and worked on communication and content strategy and web-design.
Care Provider
As the care-provider for a quadriplegic man, I assisted with his physical therapy and personal-care tasks that he was unable to do himself, cared for his children, and provided him with the support he needed to pursue his recovery.
Director, System and Networks
BeDynamic brought me on board to revamp and scale up their infrastructure in preparation for a new international customer. Over the course of almost three years, I worked to iteratively improve and expand our technological capabilities in order to meet the changing and growing needs of BeDynamic's business.
Once our changing needs slowed and stabilized, I had the opportunity to focus some of my efforts on other areas. Using custom-built tools to process and analyze trends in our product data, I identified problems, developed creative solutions, and coordinated with all involved parties to bring about positive changes.
