Core Product ✨

• Lead a team of engineers to build high-impact products, define technical strategy, write and review code and design docs, tune performance and fix bugs, work with other team leads to establish architectural patterns and processes.• Involved in the recruitment, hiring, and development of engineers as Shift grew rapidly from being a Series C startup to a public company. Conducted over 50 technical interviews and influenced hiring decisions. Onboard and mentor new engineers.• Designed and built an internal application to manage the collection, tracking, processing, and submission of physical paperwork to DMVs nationwide for vehicle titling and registration on behalf of customers.• Built multiple API integrations with SaaS vendors for vehicle tax/fee calculation, e-signatures, field staff learning management.• With a team, rebuilt appointment scheduling system to assign bookings to a pool of field staff rather than individuals. As part of this effort, built an application for FieldOps team leads to dispatch staff to appointments just-in-time and manage the pool. This work improved staff utilization rates by over 50%, a major cost driver of Shift’s “delivered test drive” offering.• Designed and built a crawler and scrubbing tool to find and de-identify customer PII across a large, highly-customized Salesforce data model containing polymorphic relationships. This tool is used to satisfy privacy compliance requirements like CCPA.• Coordinated across multiple engineering teams to design and build tools to identify and resolve major accounting data issues related to buyer and loan payments, seller payouts, and vehicle locations. Improved API integration with Netsuite ERP, reducing error rates and failing more gracefully to reduce manual bookkeeping performed by Accounting team.Primary stack: Golang, PostgreSQL, TypeScript, React, AWS.

• Designed and built an application used by mechanics to conduct 150-point inspections and track vehicle conditions throughout the reconditioning lifecycle. The backend also powers an in-field inspection iPad app.• Built a test drive appointment booking flow with React that allows customers to self-qualify themselves. This reduced the number of qualification calls made by Sales and reduced the number of test drives delivered to low-intent customers.• Added a new search filter to the car shopping experience to enable customers to find nearby cars that are eligible for a field test drive delivered to them.

• Designed and built engaging credit card rewards features and APIs to reduce the friction of redeeming rewards using Java, Spring Boot, Redis, and React.• Leveraged AWS cloud services like ECS, EC2, S3, Lambda, Route53, and CloudWatch to build resilient, scalable services.• Built CI/CD pipeline using Docker, Jenkins, static analysis tools, and ECS to reduce release time from 1 week to 10 minutes.• Contributed to internal frameworks and tools to accelerate shipping code within a highly regulated company.

• Built credit card product upgrade eligibility decisioning application using Spark, Amazon EMR, S3, and MongoDB, leading to 60% speed improvement compared to legacy system.• Developed ETL jobs to process disparate data from internal data warehouses and external credit bureaus.

• Designed and built mobile express entry system with real-time dynamic pricing for patrons at popular bars, nightclubs and restaurants using Node.js, Express, socket.io, Redis, MongoDB, Stripe, Auth0. Built iOS client with Swift to interface with the real-time backend application.• Raised seed capital.

Leveraged Chaos Monkey to identify weaknesses in cloud application resiliency during instance failure. Built proof-of-concept Node.js application to subject to resiliency testing, developed recommendations on stateless application design, and created runbook for using Chaos Monkey in Capital One environments.

Developed tool to generate synthetic network traffic based on a statistical representation of real-world traffic. Evaluated the efficacy of various AQM (active queue management) algorithms for congestion management ("bufferbloat") compared to ordinary drop tail queuing.

Researched and developed methods to integrate health data from commodity wearable devices into the core product — a competitive corporate wellness web application — to improve end-user experience and health. Designed a virtual currency system to reward users for making healthy choices.
