Software developer and architect with 20+ years of experience building systems that matter — national immigration platforms, hospital management systems, government transparency tools, and enterprise ERPs. I specialize in Ruby on Rails, Java/Spring Boot, and Elixir, with a focus on backend architecture, complex integrations, and turning legacy systems into scalable, maintainable solutions.
🎯 Current Focus
- System architecture design for scalable, maintainable solutions
- AI-assisted (agentic) software engineering and data analysis
🛠️ What I Do
Backend Architecture & APIs — I design and build backend systems, RESTful APIs, and microservices architectures. I’ve led teams defining technical standards and making architectural decisions for scalable platforms.
System Integration & Legacy Modernization — I connect complex systems together — from HL7 healthcare protocols to biometric hardware to third-party APIs — and turn aging codebases into maintainable, performant solutions.
Data Engineering & Analytics — I build ETL pipelines (Apache Hop, custom), Looker Studio dashboards, and reporting systems that turn raw data into actionable insights.
Team Leadership & Mentoring — I lead engineering teams, conduct code reviews, define architectural standards, and mentor developers. 8+ years working effectively with distributed remote teams.
