About Mark

I'm Mark Hazleton, a Technical Solutions Architect specializing in resilient systems at scale.

Expertise

Cloud Architecture: Azure infrastructure design, .NET solutions, API design patterns
System Reliability: Designing for resilience under load and failure scenarios
Integration Patterns: Data flow, event-driven architectures, distributed systems
Healthcare & Enterprise: Compliance-aware solutions for regulated industries
AI-Driven Systems: Practical AI integration and observability-first design

Experience

For over 15 years, I've worked across healthcare, financial services, and complex enterprise environments where downtime, bad data, or poor integration creates real-world consequences. I've designed platforms that route millions of transactions, coordinate distributed teams, and keep critical workflows running when things inevitably go wrong.

Philosophy

Pragmatic, constraint-aware design. There is no "perfect" architecture, only the one that fits your constraints, your risk tolerance, and your business goals. I specialize 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. I write to capture what actually works, what doesn't, and how teams can build systems that are easier to run, easier to change, and harder to break.

What I Help With

Azure Architecture & Migration

Cloud infrastructure design, Azure resource optimization, and enterprise cloud migration strategies that minimize risk and downtime.

.NET System Design

Scalable .NET architectures, API design patterns, microservices implementation, and modernization of legacy .NET applications to .NET Core.

Scalable Data & API Patterns

Event-driven architectures, integration patterns, distributed systems design, and data flow optimization for high-volume applications.

Team Capability Building

Architecture guidance, technical mentorship, code reviews, and establishing best practices for engineering teams.

Background

My path into architecture started in the early 1990s with large consulting firms — EDS and Price Waterhouse — where I learned structured enterprise systems delivery and technical architecture fundamentals. Those years gave me experience building petroleum marketing applications and working within rigorous delivery methodologies.

In the late '90s, I shifted to boutique web consulting, working on early digital initiatives like Hilton.com and portal solutions built on platforms like Epicentric and BEA Portal. This was the era when organizations were first figuring out what the web meant for their business — managing client relationships, building ROI cases, and leading delivery teams.

From there, I moved through project management roles at firms like Agency.com and FileNet integrators, eventually founding my own consulting practice in 2002. That's when I started specializing in the technical architecture work I still do today — designing web publishing platforms, integration solutions, and cloud-based systems that align with how businesses actually operate.

Over the years, I've held roles ranging from Digital Solutions Architect at CEC Entertainment to Senior Software Developer at Baylor Scott & White Health, where I've migrated legacy APIs to modern .NET Core platforms and mentored development teams. I've worked in healthcare, financial services, retail, and entertainment — industries where system failures have real consequences.

Today, my focus is on Azure-based cloud platforms, event-driven architectures, AI-powered systems, and observability-first design — the foundations required to run large, distributed systems without burning out the people who maintain them. I combine 25+ years of architecture and delivery experience with current technical expertise to help organizations build systems that stay reliable when it matters most.
