I managed 3 software development teams totaling 15 developers. I worked with product to scope work and design solutions in a custom lease management system and other systems. I was the primary architect of new features and systems for the 3 development teams. - One of the major projects that I shepherded was an integration with our corporate accounting system.- I also oversaw updating our lease management system to expand internationally. - One of the major architectural designs I completed before leaving the company was a payment system that would handle (in both an async and synchronous fashion) the running of millions of real time and recurring financial transactions. This system was designed to be highly scalable, error resistant, and self-healing. - As the company grew I took on additional responsibilities such as participating in annual and quarterly planning.

Designed and built (as part of a two man team) a new tax system to handle the 1M+ payment transactions (representing 10s of millions in revenue) monthly. This included the following:- Building a new tax service, with 2 supporting libraries- Architecting the system to use a series of caches in order to make the system performant even though our 3rd party tax provider had slow response times- Creating a series fallbacks when the taxable address was not valid so that the service always returned a rate in all but the very rarest of cases- Updating existing services to use the new system- Managing the graceful transition from the previous tax system to the new one

- Led a team which eventually grew from just me to 10 engineers to build a lease management system. This system was built to handle thousands of transactions a day for customers making scheduled payments on their leases. The system manages fees based on state-by-state statutory requirements. It charges and reports tax based on state statutes. It manages multiple payment methods including ACH, credit cards, cash, check and money order. It manages the lifecycle of the lease from onboarding the lease into the system to managing returns, repossessions, settlements, charge-offs, paying off, crediting fees and rent, managing emails, addresses, phone numbers, notes, the customer's payment schedule, taking one time payments, payment catch-up schedules (for customers that get behind on their payments), and many other features.- Built a system to take PDFs split them apart, allow the pages to be rearranged using drag-and-drop in the browser then create a new PDF with the specified page order. Also, allows pages from different pdf documents to be combined together into a new pdf in custom page order. The resulting pdfs were then classified and attached to a lease. This system was designed to streamline the processing incoming documentation for a high volume of leases.- Built a locking system in for lease editing among the customer service agents. Using Pusher and Angular I designed a system that allowed an agent to lock a lease for editing to prevent another agent from editing the same lease. It included a way for an agent to request releasing the lock which could then be approved or denied by the lock holding agent. It showed in real time any agent that was looking at a given lease.

- Built a Pinterest scraping system on Heroku (for easy horizontal scaling) that allows users to enter a domain, board, profile or interest and have alert emails sent to them whenever a customer pins an image from their website.- The system utilizes Postgres for the main database and Mongo for the analytics database and long-term archive of pins scraped from Pinterest. With this scenario I have a system that enables fast query times with highly flexible queries while at the same time allowing all pins to be mined for trending data in background processes.- Also developed a system to publish scraped pins to Facebook. As with the email alerts these social media broadcasts can be setup to be filtered by keyword.- All these systems rely heavily on Sidekiq working with Redis to schedule and process a constantly rotating background job queue.

- Lots and lots of front-end work. Implementing many new designs using Bootstrap to ensure all designs were mobile friendly.- Did some work with Stripe updating the membership plan model several times.

- Implemented an online document signing framework for signing financial documents for rent-to-own businesses. The framework leveraged the Right Signature 3rd party signing service.- Built a custom financial calculator in Javascript for rent-to-own contracts and then built out the corollary implementation on the server side.- Implemented the front-end styles for the whole system using CCS3 and the asset pipeline.- Built out a check-out system including a product and order system to handle the supply requests of Simple Finance's vendors. This check-out system include integrating a third-party fulfillment services to have all order automatically fulfilled.- Built out user and contract management system which included a pretty extensive state machine to ensure that system handled each stage of the contract approval process correctly.
