Staff Software Engineer

At EasyPost I was responsible for designing and architecting new services, while extending and maintaining existing ones. The majority of my contributions have been on the merchant logistic side to EasyPost's fulfillment and carrier service businesses, both client facing and internal.

• Designed, engineered, and maintained EasyPost Carrier, a micro-service to support EasyPost's own carrier service offering. It provides a solution for clients to freight batches of pre-packaged shipments to an EasyPost facility, where we would then re-label them so they could be sent out and delivered through a 3rd party carrier such as USPS or FedEx within the desired service level. The service integrated with the core EasyPost REST API and allowed for clients to get rates, purchase labels, and receive tracking updates for their shipments as they could with any other carrier. It also has an internal facing API which is consumed by the EasyPost mobile applications in our facilities.

• Designed and implemented order crediting system within EasyPost's fulfillment business, allowing support engineers and operations managers to give credits to vendors for order issues.

• Eliminated much of the duplicated code in the EasyPost core API by writing concerns to support common operations between carrier accounts for fetching rates, buying labels, and issuing refunds.

• Designed and engineered Manifester, a service used to auto-manifest batches of shipments on a daily basis at our various warehouse facilities. This alleviated work load on operations who before had to manually batch together each facilities shipments for each different carrier every day. The service supports both fulfillment and EasyPost Carrier.

• Implemented new API's for receiving inventory in our fulfillment warehouses. This included both a client facing and internal facing API to improve organization when receiving new inventory. Implemented dual write logic and backfill process to convert existing data.

At OneMob, I was responsible for leading architecture design, data modeling, and API development. My main goal was to build a robust and flexible application which could support both enterprises with large teams as well as small companies/individual users.

Specific projects included:

• Rebuilding the MVP into a scalable standalone application. The original application was dependent on Salesforce for user authentication, and had some shortcomings in its architecture and API design. I worked to rebuild and improve the architecture, decouple it from Salesforce, and design an agnostic REST API for each of the 4 different client applications (iOS, Android, Salesforce Package, Chrome extension) to use.
• Integration with various API's including Stripe, Zencoder, Filestack, Salesforce, Intercom, and Mixpanel.
• Front end development on the single page web application in Angular 1.5. Web RTC development on the OneScreen Chrome extension to allow for screen and webcam recording.
• Updating the application from Rails 4.2 to 5.0.
• Leading code reviews and pull requests, giving feedback to the other engineers.

Software Engineering Intern

I have 5 years of experience working on large monolithic applications, doing API development and architecting schemas. I have also built a number of smaller micro-services using these technologies.

I have 5 years of experience architecting, maintaining, and extending applications using Ruby on Rails. I have used Rails as both an API only as well as a full stack service. I've worked on large monolithic rails applications and created new micro-services in rails. 

I'm highly experienced with relational databases such as MySQL and have architected applications, migrated data, written complex queries, and analyzed performance issues relating to proper indexing.

I have strong experience with Python, primarily for API web development using the Flask framework, and have built an application from the ground up using it. 

I am currently using Go daily in my professional environment and have done a couple of side projects in it as well. I also had some exposure to it in my previous role and have read the books "The Go Programming Language" and "Concurrency in Go" from cover to cover. 

I previously worked in a full stack role doing both frontend and backend development, and have built out a number of web pages, both static and dynamic.

For frontend development, I've primarily used AngularJS, but also have developed a chrome extension which used React.
