PresentBuilding a next generation global systematic trading platform.
I’m a software engineering consultant in the greatest city in the world, New York, working with businesses of all shapes and sizes to solve their problems with technology.
This site is intentionally under construction forever.
Building a next generation global systematic trading platform.
Led UI development for a quantitative research platform.
Led a two-developer rebuild of the iOS and Android apps; worked with product stakeholders and the CreditSights team to gather API requirements.
Built the React Native apps for iOS and Android, integrated with the existing web product, and collaborated on GraphQL APIs backed by Rails.
Built a ChatGPT integration that lets Reportable users generate press releases.
Led a ground-up rebuild of ObscuraDAO’s NFT marketplace and moved site updates into a CMS the nontechnical team could manage.
Full-stack development and ongoing maintenance of a complex interactive app for photographers as founders onboarded customers.
Led a CMS and component library for no-code marketing emails. The 2021 soft launch began sending campaigns to 10% of CreditKarma’s 100M+ users.
As the first frontend hire, rebuilt the monitoring platform with a three-person team and launched in six months, focusing on big-data visualization and alerting.
Led development of a dynamic, headless-WordPress site for branded stories, serving millions of monthly visitors.
Took a hack-week prototype to production in six weeks and built an image-resizing tool that exports a ZIP of ready-to-use images.
I like the part where design and development overlap: making complicated systems understandable, useful, and maybe even pleasant. My academic background is in Human–Computer Interaction and Computer Science, which means I have opinions about both the interface and the code underneath it.
I specialize in React, Vue, and TypeScript, plus the surrounding front-end ecosystem. I also work across the stack when that is what getting the job done requires.

If your street sign uses Comic Sans or Papyrus, I would genuinely like to see it.
