Hi! People call me Tom.
I'm a Senior Applications Developer at King County.
Right now I am building a web app to manage and edit Road Assets like stop
signs and crosswalks using the Next.js front-end framework and ESRI's ArcGIS JS mapping library. The
back-end of this app is composed of authenticated APIs exposed through Azure's API Management service and
Feature Services exposed by ArcGIS Enterprise.
This web app is a direct reimplementation of a decade-old app that was built on the now deprecated Silverlight 👀 framework from Microsoft.

In support of my brother's company, I wrote a console application that scrapes phone numbers that are
available for purchase from a pair of SOAP APIs and a REST API, and then aggregates them into a local
database. You can review the results of ingest process and quickly lookup available phone numbers on the Accelerate Networks website.

My primary responsibility at Kitsap County was maintaining the public parcel information system. Parcel
Details is a web app that allows anyone to look up a tax parcel in Kitsap County.
Parcel Details was originally an ASP.NET 4 WebForms project that used rapid application development tools
a vendor to define its business logic and user interface. Since I took over it's maintenance, I've upgraded
the project to .NET 4.7.2, lead a redesign of the user interface, rewrote the business logic and views to
remove all dependencies on the vendor's tools, and migrated the database calls from ancient ADO.NET Datasets
to a micro Object Relational Mapper (ORM) called Dapper.
What I'm most proud of is getting the average page weight down from 6 MBs to less than 200 KBs. This was
achieved despite the addition of a responsive CSS framework (Bootstrap 3.3.7), helpful icons, and a variety
of new interactive features.
This summer I rebuilt Parcel Details as an ASP.NET Core 2.2 MVC project. It took about 300 hours port the
data access layer and then rebuild the business logic and views in the MVC format. To prevent service
interruptions this was a pixel perfect rebuild. This required careful testing to verify that there were no
impacts and the use of ASP.NET Routing middleware to remap the routes of the old app to the structure of the

Plats Search is web app that
allows you to look up survey and plat documents related to a tax parcel.
It's an ASP.NET Core 3.0 project that I wrote from the ground up. Razor pages are used to define the views,
Bootstrap is used to style the views, and Entity Framework Core 2.2 is the ORM we used to handle database
Getting a hold of Plat Records from most Counties in Washington requires going through the formal records
request process. Plats Search circumvents this process by allowing people to search for Plats related to a
tax parcel and directly download scans of those source documents.

I like camping. Often I'll go out to the Olympics and stay at sites like Lake Cushman, Deer Park, and the
coastline around Lake Ozette. I'm also looking forward to ski season this winter.
For fun I've reimagined Kitsap County's parcel viewer as a 3D web map built on top of the MapboxGL.js library and
the County's open data dumps.
I also know a bit about photography. You can see my work on
Flikr. Right now I'm shooting with a Sony RX1R MKII.
As of October 2019 I am the author of the top text result on Google for "How
to install RAM". Although I don't
write product reviews anymore, I still have a deep interest in computer hardware.
I'm helping my dad rebuild his old pickup truck. You can see my project tracking repo on GitHub.

Performance is a feature. Identifying the most effective compromise often begins with a clear understanding
of a project's purpose and constraints.
