Mark HazletonSolutions Architect/Developer

About Mark

I'm Mark Hazleton, a solutions architect/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

There is no perfect architecture, only the one that fits your constraints, your risk tolerance and your business goals. I work in the space between software and operations, where APIs, cloud infrastructure, security and people collide. That's where most failures happen, and where good architecture makes the biggest difference.

I care less about frameworks and more about whether a system will still work at 2 a.m. when something breaks. Project Mechanics is how I manage the work, and DevSpark is how I build 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.
