Staff Software EngineerTock Feb 2021 - May 2023Chicago, Il, UsI joined Tock when it was around 50 people and just starting to see product-market fit. I was there during the entire hyper-growth stage all the way up through acquisition.- Managed a team of engineers building the business-facing side of the application.- Rapidly iterated on new restaurant management features as our customers’ requirements were quickly changingdue to the impact of COVID.- Led the effort to migrate a suite of read-only restaurant management tools into self-serve tools, reducingonboarding time by months and drastically cutting down support costs.- Made table reservation and management more efficient, allowing us to onboard large enterprise customers.- Built many features to maximize revenue for restaurants by fitting more guest reservations within their constraints.- Repurposed many restaurant-specific tools into a more generic Events platform.- Successfully drove adoption of GraphQL for all new API development, resulting in improved developer velocity.- Created a system that enabled all developers to quickly build real-time functionality into our applications. -

Senior Software EngineerSwipesense Inc. Aug 2018 - Feb 2019Chicago, Il, UsI came to SwipeSense right as we started migrating from a Rails monolith (with a single MySQL database) to a wide range of microservices and datastores. Since then, we've tackled many challenges when it comes to ingesting large amounts of sensor data and efficiently presenting useful insights to users.I work on every part of the stack. Our infrastructure is all on AWS. Our frontends are React-based. Our backend code is a mix of Python and Go (running on AWS Lambda) and Ruby (a Rails app running on EC2 instances). Our data lives in MySQL, Postgres, and DynamoDB. We have an awesome GraphQL API that powers most of our services, both user-facing and internal.Some things I've personally worked on:- Built a tool to visualize and modify hospital floor plans. An error-prone process that used to take a whole week now takes a few hours, with no errors in the output.- Built a series of tools that allowed us to tweak our algorithm that predicts where a sensor is inside a hospital. You can't improve what you can't measure, and I built a very intuitive way to measure the result of changes to this algorithm.- Used Docker to bundle up all the dependencies of all our repositories. Getting up and running with certain repos used to be a long-winded installation process full of trial and error, but now it's a simple `docker-compose build`.- Migrated parts of our system to more horizontally scalable infrastructure. No more database scaling issues or single points of failure.- Built a bunch of ETL processes that aggregate raw data into something digestible for users.- Built a GraphQL API to expose any data we want to share between multiple parts of our system. We originally built this to feed our frontend apps (React + GraphQL + Apollo is a magical combination), but we found this API to be so useful that we started having our internal microservices use it as well. -
