We are working on a next-generation software infrastructure platform to power Doordash and its acquisitions to the next 100x scale.

As an infrastructure engineer within the Risk organization our charter was broad. We managed massive deprecation and migration projects for the core Square payments flow but also built tooling, infrastructure and platform support to materially improve the lives of product-facing Risk teams. I led the enormous migration of the core payment flows from legacy endpoints and codepaths in a service we didn’t own into the more modern generic flow; dealing with every kind of tech debt you can imagine… Show more As an infrastructure engineer within the Risk organization our charter was broad. We managed massive deprecation and migration projects for the core Square payments flow but also built tooling, infrastructure and platform support to materially improve the lives of product-facing Risk teams. I led the enormous migration of the core payment flows from legacy endpoints and codepaths in a service we didn’t own into the more modern generic flow; dealing with every kind of tech debt you can imagine. The completion of this migration saw no impact to payments flow nor to the Merchant experience. My vision turned that migration work into two different services providing sync and async platforms for teams to write the minimal amount of boilerplate and to be able to instead focus on their core business logic for integrating new Square products into the Risk flows. My work extracting an embedded risk state machine from our payouts service allowed us to build payment’s backstops; giving us graceful degradation options when ML platforms -or any upstream service- had issues. My work ensured that Risk took back ownership of key decision points along the payment flow. I led my expanding team on platform best practices such as business level metrics, in-depth metrics boards, reliability and retry philosophies and pushed myself and the team to experiment with whatever technology we could get our hands on. The open, supportive but assertive culture we built ensured that even junior engineers had room to grow with a solid model for what excellence looked like. Our investments in team culture and self-direction created a team providing consistent, valuable services and improvements to our sister Risk engineering teams. Show less

With the acquisition of JUMP and the explosion of both Bikes and Scooters I was on the forefront of our internal rewrite to support those business at Uber scale on Uber hardware and with Uber platform tools. I was a foundational architect of our solution and brought the project from conception to reality in dozens of markets worldwide, supporting rider and operations usecases. I help set the technical direction of my team and provide deep technical guidance on core Bikes and Scooters… Show more With the acquisition of JUMP and the explosion of both Bikes and Scooters I was on the forefront of our internal rewrite to support those business at Uber scale on Uber hardware and with Uber platform tools.

I was the primary developer in charge of our financier charge portal. We allowed (with driver permission) third party leasing and rental agencies around the world to deduct their weekly charges directly from driver earnings. I inherited a legacy Python service and solidified with with deep refactors and re-imaginings of core processing pipelines.

As a technical leader with several years of experience I provided guidance on team road maps, dove into deeply complicated projects such as distributed pivot facets and helped Shepard the search team into CareerBuilder's nascent micro-services environment.

Involved in the expansion and streamlining of CareerBuilder's Solr search services.

Supported large-scale Solr clusters by defining, updating and maintaining the interface between the Solr search servers and the CareerBuilder platform.

On site computer repair service. Trouble shooting and upgrading as well as performing Lenovo warranty work. Some of the work performed consisted of computer component installation as well as spyware and virus eradication followed up with firewall and anti-virus software installations.

In tandem with another tech, responsible for the upkeep of two of the district's four school buildings. This included everything from software roll-outs to hardware replacement/upgrades and general computer troubleshooting. As part of a rotating technology update to the district, was involved in the installation of "Smart Boards" and large computer roll outs for various building wings and computer labs.

With the buildings mostly empty, projects centered around large district wide computer roll-outs and relocations. District wide re-imaging occurred and all necessary software and drivers were added to ensure a smooth transition to the coming school year. Server reorganization and expansion also occurred in the latter summers.
