Summary
A seasoned developer, architect and mentor, of 24 years experience.
I helped deliver countless successful projects, on teams large, small and diverse.
Even single-handedly in some cases.
I focus on how to ship a profitable project on time, by smart use of current
practises and technologies. And I make sure the client is happy with the result,
and the way we worked together.
I have also helped clean up huge code-bases, to the point where changes are
cheap again.
Self-driven and self-motivated, but always sharing and communicating. When
something holds me – or the team – back, I let the right people know, immediately.

My core principle is to be of value.

.NET Web developer at SwayingWords.
Skills: C#, .NET, Javascript, JQuery, ASP.NET MVC, Razor, TDD,
Markdown, Bootstrap 4, HTML 5, CSS 3, SQL Server, IIS
I automated and saved countless hours of doing repetitive tasks, by creating
my own custom ASP.NET MVC blog platform and marketing app for my
copywriting business at SwayingWords.
• I enabled quick generation of multiple formats – like HTML5, PDF or
DOCX – from Markdown in VSCode
• I designed custom server-side markup to enable includes, layout templates,
Razor scripts, and a file-based information architecture
• I added client-side code using HTML5, CSS3, Javascript and JQuery –
for custom tracking, and integration with Drip (email automation), 2Checkout and PayPal payment gateways.
I also handled many challenges of running a small business, including how to
look for attitude and work ethic in the people I hire.
October 2013 to January 2017:
Senior Developer at Infovest Consulting
(3 years 4 months)
Skills: C#, .NET, Javascript, WPF, MVVM, Entity Framework,
TDD, ASP.NET, HTML 5, CSS 3, Scrum, SQL Server, IIS, Jenkins,
TFS, Data warehousing, mentoring.

I took on a senior role in advancing the code base of a large WPF application. I
led the team on test driven development (TDD), using proven design patterns,
and automated unit testing.
I built and maintained a Jenkins based continuous integration build servers,
and other tools and frameworks to automate repetitive tasks within the team.
The result was shorter – and more frequent – release cycles, which made us more
agile in responding to changes in our clients’ needs, without racking up too
much technical debt.
"I had 100% trust in Leon’s ability and rated his input
highly.
This extended to efficiency. I knew he was always looking
for ways to increase efficiency and getting the job done
quicker by using all the tools at his disposal. His communication was good, even though not always expert at some
of our domains.
The way we worked changed vastly after Leon joined. He
added tremendous value in our product development
processes. As a result, our release cycles got shorter
and risk decreased."

charge or technology decisions, and maintaining tight unit testing discipline
for each project.

On top of this, I built and maintained tools and frameworks that automated
tasks for the team, including a continuous integration build server.
