HubSpot Report Builder

https://knowledge.hubspot.com/articles/kcs_article/reports/create-custom-reports
At HubSpot, one of the projects I worked on was heading up the front-end development of the new HubSpot report builder, designed to help customers unfamiliar with traditional reporting tools create effective reports. On this project, I had the opportunity to work with a large organization to pull together dependencies from multiple teams, as well as structure the project from the ground up and on-board new team members into the project later into development.

Stuff4Hire (React Development)

Stuff4Hire is a platform which allows neighbors to rent the everyday items they own but only use occasionally.

I took over development of Stuff4Hire from another developer, a project built with React + Redux, developed a plan to improve the code base and prepare for production, and worked with the founders to build out features to launch the project into beta.

Noir Gallery

I partnered with Noir Gallery to build a beautiful e-commerce platform to allow artists to monetize their work.

I led a small team to build an eCommerce platform to support Noir Gallery's large catalog of over 50,000 artworks from hundreds of artists, built an automated system to synchronize orders from many sales channels into a central database for the fulfillment, built internal tools to manage Noir's business processes and built a beautiful, easy to use the portal for artists to upload and manage their artwork and shops. We used TypeScript, React, Svelte, Clojure, and Datomic deployed on AWS for this project.

One of my favorite parts of this project was building a custom query optimizer in Clojure for Datomic to eliminate slow database queries.

Fight For Black Lives

In the wake of George Floyd's murder, my and my business partners were motivated to launch a simple site to help citizens demand change from their local representatives via Twitter.
