I'm a senior frontend engineer with 8+ years building production web applications, specializing in React, Next.js, and TypeScript. Most of my career has been spent on complex, data-heavy UIs — security dashboards, risk platforms, real-time feeds — where the architecture decisions have real consequences on performance, maintainability, and team velocity.

I care about the reasoning behind decisions, not just the decisions themselves. This site is my attempt to document that reasoning: the frameworks I use to think about state, composition, data fetching, and rendering — and the patterns I reach for when building production features.

Experience

Senior Frontend Engineer — Digg

Jan 2026 – Feb 2026 · Remote
  • Shipped community discovery and notification features ahead of a public launch that grew the platform from a few thousand to 100,000+ users within a month.
  • Built a custom masonry grid integrating infinite query and virtualization to handle large dynamic content feeds at scale.
  • Diagnosed a cache normalization problem in the React Query + GraphQL setup and contributed to the custom client cache that resolved stale UI state across shared components.

Senior Frontend Engineer — Coalition Inc.

Jul 2022 – Sep 2025 · Remote, San Francisco
  • Led the rewrite of the Coalition Control application in Next.js, React, and TypeScript — a security posture dashboard with interactive analytics serving 30,000+ users.
  • Built a frontend component library on Material UI, packaged as an npm package and adopted across security applications to unify design and streamline development.
  • Established AI-powered development workflows using Cursor and Claude Code, including custom localization scripts that cut per-language implementation time from days to under 1 hour.
  • Designed and implemented an auto-generated TypeScript API SDK, reducing developer-written code by 25%.
  • Built end-to-end testing with Playwright and monitoring with Datadog RUM and Sentry.

Senior Frontend Engineer — RepRisk

Jul 2019 – Jul 2022 · Toronto
  • Led a comprehensive rewrite of the core React application to Next.js, Node.js, and TypeScript.
  • Architected a full-stack solution with a Node.js middleware server and GraphQL API, containerized with Docker.
  • Built a centralized UI component library used across multiple applications.

What I'm building here

renderpx is a living reference for the architectural decisions I make and the patterns I've found most useful in production. Each framework is a structured way of thinking about a category of frontend problems — not just a list of best practices.
