The most amazing...

...thing was when the client's head of IT asked to use my estimation engine for pricing—it was faster and 100% accurate as compared to manual work.

Employment

  • Senior Staff Developer

    2016 - 2019
    Pivotal
    • Developed a system to value the trillions of dollars in assets of a multinational bank in minutes for any selected denomination.
    • Designed an estimation engine for a health insurer that was more accurate than the (then current) pricing engine.
    • Increased the efficiency of an in-house reporting task force by 300% for a data technology client.
    • Developed a front end compliant with the web content accessibility guidelines (WCAG) level AA for a national credit card issuer.
    • Created a visualization system to see the (relative) employee efficiency of over 400 healthcare systems.
    • Modernized the handling of ACORD data for a national commercial insurer. While developing the new system, we discovered two critical issues with the current systems during a side-by-side comparison.

  • Senior Developer

    2015 - 2016
    Captricity (now Vidado)
    • Split up a monolithic computer vision service into four services.
    • Created a performance testing framework so that the QA department could execute performance tests against any system and environment.
    • Resolved several critical performance issues (one within my first week of joining) that if left unresolved would have led to service level agreement damages in the hundreds of thousands of dollars.

  • Developer

    2013 - 2015
    Thoughtworks
    • Integrated with a documentation-less mainframe to create a system capable of creating over 400 account statements in minutes for a large multinational bank.
    • Created an infrastructure-as-code system to deploy an application with a database before the advent of Docker.
    • Resolved a severe bug in AWS cloud-formation that prevented resources from being freed. This bug had been open for over four months and the resources that hadn't been freed were billed to the client, a major airline.

Experience

  • Health Care Cost Estimator
    https://my.providerfinderonline.com/?ci=IL-NOEX-PUBNETS

    A Java Spring application that allows health insurance members to preview how much an operation/physician visit would lower their remaining deductible/maximum out of pocket.

    I was the lead developer for this project and, alongside general development, also created a tool to make side-by-side comparisons against the legacy pricing engine. This project's general success led to it becoming the primary source of prices in the client architecture despite not being a goal of the project.

  • Discover Credit Card Application
    https://www.discovercard.com/application/website/apply?srcCde=KXPA

    A Java Spring application that handled all new credit card applications to Discover and was responsible for serving the user interface, validating said application, and sending valid applications to the mainframe.

    I was the lead developer for this project.

  • Portfolio Valuation

    A Java Spring application that enables the bank to value all of their customers' holdings in any and all desired currencies at any point.

    I was the lead developer for this project. The system needed to value assets that ranged from personal holdings to billions of dollars worth of varied asset types. It processed every portfolio in a matter of minutes (even less when we dedicated more machines to computation).
