Consulting

Last updated:

Heads up: I'm currently Principal Engineer at Monarch — a full-time role. Any consulting I take on happens outside those hours, on nights and weekends. I'd rather you know that right up front.

I partner with companies to design and build web products end to end — from creative, animation-forward experiences to complex enterprise and healthcare systems where the work is data, performance, compliance, and security. I usually plug in as a principal/lead engineer or a long-term technical partner.

How I work

  • Partners, not clients. I treat your product like my own startup and align my work to business impact, not just deliverables.
  • The next most useful thing. Momentum is gold. I'm always looking for the blocker to remove or the move that pushes the product forward.
  • Forward-thinking and grounded. Positive but realistic — solutions that actually work within real technical constraints.
  • Strategy and hands-on work. I live in both the big-picture architecture and the day-to-day implementation. Strategy without execution is theory.
  • Numbers and empathy. Data should guide us, but in healthcare especially you have to understand people too. I care about measurable impact and the experience of the humans using the tools.

Engagement & availability

I work on flat monthly retainers, typically a three-month minimum, starting around $6,000/month. I'm currently Principal Engineer at Monarch, so my availability is limited and outside work happens beyond office hours — but I genuinely love creative, complex side projects and can usually fit the right one in. The best move is to reach out and ask.

The stack

TypeScript, Next.js, React, Vue/Nuxt and Tailwind on the front end; Node.js by default on the back end, with Python/Flask for agentic/AI work (and Laravel and Rails in the toolbox); PostgreSQL, AWS and Google Cloud, CI/CD, and HIPAA-grade compliance when it's called for. The full picture lives on the Tools page.

Selected work

  • Looking Glass Factory (holographic display startup) — 6+ years. I built the first version of their website and helped raise millions in investment and sales, through several major redesigns and stack migrations: a static site with SnipCart → WordPress + WooCommerce → a custom Vue/Nuxt storefront on a Shopify backend. I also shipped customer-facing products, including an app that turned 2D photos into 3D/holographic portraits.

  • Monarch — As Principal Engineer I built and launched a medical membership platform that generated hundreds of thousands of dollars in its first weeks (MVP in seven days), then led a rebrand and a back-end migration. It's now a HIPAA-compliant platform managing multiple practices and thousands of patients, with agentic workflows, a system for spinning up new sites and pages fast, integrations (Athena, HubSpot, Stripe, Aircall), and reliability tooling.

  • Leap Health — the only US nationwide infusion provider built for employers. I architected a desktop claims-analysis platform that ingests millions of records and replicates expert-analyst judgment at ~99% parity (turning hours into minutes), plus a scalable drug-pricing intelligence system, and drove infrastructure, cross-platform deployment, and CI/CD.

  • Feels Like Studio — maintenance and compliance work for a major entertainment company's site (under NDA), and two highly creative, interactive experiences for a major search engine's flagship developer conference, built with Next.js + Python/Flask and an agentic AI stack.

  • Graphite Health — led the front-end for the website redesign: a high-performance, visually compelling platform for investors, collaborators and talent, with Sanity as the CMS and custom integrations.

  • Atlanta Life (with weirdo.design) — built the site from a Next.js + TinaCMS iteration into a custom CMS on PostgreSQL, integrating multiple insurance sites, complex auth, and third-party systems.
