Plum Co-Ownership

Sep 2021 – Dec 2023 | Ruby on Rails

Plum CoOwnership, Inc. is a venture-backed vacation co-ownership platform company that makes it 10x easier for people to form a group, buy a vacation home, and co-own it together gracefully.

Led the technical development of Plum Web, a Ruby on Rails 7.1 co-ownership real estate marketplace platform, as the primary contributor with over 1,494 commits representing 60% more contributions than any other team member. Architected and implemented core business systems including the Dreamboard property preference engine, public-facing Marketplace platform with MLS (Multiple Listing Service) integration, and collaborative Proposals system for co-ownership management. Delivered comprehensive RESTful APIs, real-time voting mechanisms, and automated member onboarding workflows that enabled the platform to serve both B2C marketplace and B2B partnership integrations.

Created extensive test coverage with 60+ test factories and maintained code quality through StandardRB linting and Brakeman security scanning. Developed modular routing architecture, service objects for business logic separation, and View Components for reusable UI elements following Rails best practices and clean code principles.

Modernized deployment infrastructure by migrating the application to Kamal containerized deployment on Digital Ocean, reducing deployment complexity while improving scalability. Implemented comprehensive CI/CD pipelines using GitHub Actions for automated testing and deployment to staging and production environments. Established secure secrets management with 1Password integration, automated backup systems, and monitoring with Airbrake and New Relic.

WingTask

May 2021 – Sep 2021 | Ruby on Rails

WingTask is a mobile UI for the popular opensource command line task manager, Taskwarrior. WingTask is an app wholly created by me and represents my desire to build and launch my own app as well as trying to provide a useful addition to a CLI app that I use daily.

1bios

Dec 2018 – Apr 2021 | Ruby on Rails

1bios is a complex set of RubyonRails applications that serve different populations of users. It has a web admin area that is mostly Rails and React. It also has a mobile frontend that is React being served from a Rails API. The app is unique in that it's a monorepo containing about 3 or 4 different Rails apps being serviced by a Ruby middle tier library

BidSketch

Feb 2015 – Dec 2017 | Ruby on Rails

Worked on an unreleased app called Docsketch which is an electronic signature signing app similar to HelloSign or RightSignature. Using React I created the ability for a person to drag and drop signing elements onto an uploaded document in order to specify what needs to be executed for the signing.

TaxJar

Dec 2014 – Dec 2015 | Ruby on Rails

Created a ruby client for the TaxJar API. The ruby client made it easy for other ruby devs to pull data from the TaxJar REST API, JSON was the data format returned and that was converted into ruby objects.

Econify

Oct 2014 – Dec 2014 | Ruby on Rails

Econify created an app for selling parts in an Ebay like market for the large machine industries. For instance, it allowed people who had spare parts for locomotive trains to sell parts to one another. I worked generally on fixing bugs and adding features to this marketplace app

EndPoint

Mar 2011 – Sep 2014 | Ruby on Rails

Harvard Law commissioned End Point to build an app called H2O which is a platform for creating, sharing and adapting open course materials. While this app was adapted for many other institutions initially it allowed Harvard Law Professors to upload PDF copies of US court cases that would be part of the curriculum for Harvard Law students. I worked on an annotations feature which allowed a professor to share annotations of a document to their class as well as allowing a student to add their own annotations. There was a versioning component to this that also allowed viewing annotations at different points in time.
