Software Architect
I Turn Legacy Systems Into Scalable Cloud Platforms
20 years modernizing enterprise platforms — from monoliths to microservices, on-prem to cloud. I've delivered in healthcare, finance, and SaaS, where architecture decisions have to be right the first time.
What I Do
I specialize in turning legacy enterprise systems into modern, scalable cloud platforms.
Cloud Modernization
Migrate legacy monoliths to scalable cloud architectures on AWS and Azure. Reduce infrastructure costs, improve reliability, and unlock the ability to ship faster.
Enterprise Architecture
Design system architectures that align technology investments with business goals. Scalable, secure, and built for compliance from day one.
Event-Driven Systems
Build reactive, loosely-coupled platforms using event-driven patterns for real-time data processing, claims pipelines, and system integration.
How I Work
A straightforward engagement model designed to get you from legacy to modern with minimal risk.
Discovery
We start with a deep dive into your current architecture, business goals, and constraints. I identify technical debt, risks, and opportunities for modernization.
Architecture
I design a target-state architecture with a clear migration path. You get detailed diagrams, technology recommendations, and a phased roadmap your team can execute.
Delivery
I can embed with your team to lead implementation, or provide advisory support as you build. Either way, I stay engaged until the architecture is proven in production.
Industries I Serve
Deep domain expertise in the regulated industries where architecture decisions matter most.
Healthcare
Modernizing platforms that power hospital pricing, claims processing, and clinical data analytics — with HIPAA compliance built into every layer.
- Hospital pricing transparency platforms
- Claims processing pipelines
- Serverless healthcare analytics
- Multi-tenant SaaS for health systems
Financial Services
Building secure, scalable architectures for digital banking, payment systems, and financial reporting — meeting PCI and SOC 2 requirements.
- Digital banking platform architecture
- Core system integrations
- Microservices for financial products
- Infrastructure as Code for regulated environments
Results
Quantified outcomes from real modernization projects.
Case Studies
Health Catalyst
Challenge
A healthcare analytics platform needed to scale from a traditional SQL Server architecture to serve 200+ hospitals while maintaining strict HIPAA compliance.
Solution
Architected a migration to Azure serverless with event-driven claims processing pipelines and multi-tenant data isolation. Led the team through a phased modernization with zero downtime.
Major Regional Bank
Challenge
A regional bank needed to launch its first digital banking platform, moving from a legacy monolith to a modern microservices architecture on AWS.
Solution
Architected the bank's first AWS-based microservices platform. Introduced Infrastructure as Code and CI/CD pipelines, enabling rapid delivery of new digital banking features while maintaining PCI compliance.
Sertifi
Challenge
A growing SaaS company needed to modernize its legacy .NET platform to improve developer productivity and reduce operational bottlenecks.
Solution
Defined architectural standards and a technical roadmap for platform-wide modernization. Migrated legacy apps to SDK-style formats and introduced Datadog observability for proactive monitoring.
What People Say

About Me
I'm Rigo Macias — a Software Architect based in Milwaukee, WI with over 20 years of experience designing and modernizing enterprise platforms across healthcare, financial services, and SaaS.
My work focuses on the intersection of cloud architecture and regulated industries. I've led modernization initiatives that cut infrastructure costs by 35%, improved platform uptime to 99.99%, and scaled systems to serve 200+ hospitals nationwide.
I hold a B.S. in Computer Engineering from the Milwaukee School of Engineering. Beyond architecture, I'm passionate about mentorship — I've guided multiple engineers into senior and architect roles through coaching on design patterns and architectural thinking.
My technical depth spans AWS, Azure, C#/.NET, microservices, event-driven systems, and Infrastructure as Code. I bring both the hands-on engineering skill and the strategic vision to align technology with business goals.
