Work Experience

Senior Software Engineer

2017 - PRESENT
  • Developed a tool that successfully migrated data after I was acquired from Reserve Media (defunct). Migration consisted of two million guest profiles, 22 million reservations, and 700 venue floorplans.
  • Allowed Resy to publish paid inventory to Google to allow diners to book reservations (via Google) that required credit card information.
  • Wrote several tools (e.g., Slack bots) that project managers and non-technical support teams can use to debug issues and retrieve information quickly.

Lead Software Engineer

2021 - 2023
  • Mentored a team of four remote engineers and paired with them for bug hunting and development.
  • Developed documentation, readmes, and Postman collections for developers to quickly test API endpoints across local, staging, and production environments.
  • Removed legacy code to reduce the monthly Google Cloud Platform (GCP) bill, decision fatigue, and developers' context switching.

Senior Software Developer

2020 - 2021
  • Developed and published the company’s apps for Android and iOS using React Native.
  • Assisted the back-end team in adding endpoints to their API (Node.js, TypeScript, MongoDB) and refining ElasticSearch indexes and queries for more intuitive searching of vendors and products.
  • Suggested ways to improve the development experience since onboarding was not intuitive.
Technologies: React Native, Next.js, React, Bash Script, JavaScript, TypeScript, Mobile Development, CSS, Go, Xcode, HTML, Google Kubernetes Engine (GKE)

Software Engineer

2013 - 2017
  • Developed a dashboard-style web page using Node.js and Angular to monitor nightly jobs and system resources to better understand process runtime and data growth rate.
  • Rewrote portions of the nightly Perl-based data load process to make it leaner and easier to test changes. Also added features and fixed bugs as requested by stakeholders.
  • Developed portions of a read-only API that allows front-end applications and other stakeholders to retrieve data from the ownership (security holdings) dataset.
  • Established team-wide best practices and wrote several scripts to automate onboarding, and mentored newly hired engineers.
  • Educated product managers and research assistants on generating reports using SQL and Excel by holding quarterly SQL workshops.

Programmer Analyst

2011 - 2013
New York University
  • Developed modules using the .NET framework for an internal building management system that tracks space usage across all university campuses and buildings.
  • Enhanced a capital project management system written in PHP and Microsoft SQL Server by adding several dynamic and exportable reports for project managers and fiscal officers.
  • Automated invoice aggregation and EDI generation for accounts payable by modifying an application that ran as a Windows service.
  • Wrote PHP scripts and SQL Server stored procedures to reconcile purchase order information with the university's purchasing system.

As a co-founder and CTO, I was the lead (and for the most part, the sole) developer on this project, working on the Angular front-end, Node.js back-end, MySQL database, and ETL framework written in Bash and Python. The web app is meant to provide a consistent interface for retrieving schedules and realtime vehicle data for transit systems across market cities that conform to the General Transit Feed Specification (GTFS), which is developed and used by Google. The data load framework made adding new market cities simple and easy to do. Since a lot of the features of the web app have been integrated into Google Maps (and now, even Apple Maps), this project has been mostly abandoned. However, it was a great learning experience.
