About Mark

I'm Mark Hazleton, a solutions architect and hands-on application developer with decades of experience across consulting, enterprise and healthcare. I turn ambiguous business intent into systems that keep working, and I still build them myself.

Currently the Engineering Lead at Baylor Scott & White Health, since August 2020. I'm the solutions architect and a hands-on developer for a digital front-door program that helps visitors find the right type of care. I set the vision, design the solution and build it, leading a squad of developers across API, web, mobile, CRM and engagement, and analytics.

How I work

I solve the problem, then get out of the way. Getting out of the way means the business can run, change and own what I built without depending on me. The relationship keeps going; the dependency doesn't.

I care less about frameworks than about whether a system still works at 2 a.m. when something breaks. Two methods keep me honest about that: Project Mechanics for managing the work and DevSpark for building the software. I write to capture what actually works, what doesn't, and how to build systems that are easier to run, easier to change and harder to break.

Career

For the systems I build in public, see the work.

Focus areas

  • Cloud architecture: Azure infrastructure, .NET solutions, databases and API design

  • Integration: data flow, event-driven architecture, microservices and distributed systems
  • Healthcare and enterprise: compliance-aware systems in regulated industries

Explaining technology to people who don't build it is part of the job.
