Capabilities
How I approach the work.
Skills are more useful in context than as percentages. These are the areas I draw on when designing and maintaining systems.
Systems & architecture
System design · API integration · Data modeling
Applications
TypeScript · Next.js · React · Laravel
Data & infrastructure
PostgreSQL · SQL · Docker · Linux · Git
Infrastructure & delivery
Deployment, documentation, integration, and continuous improvement.
Working principles
The standards behind the systems.
Start with people
Understand the real workflow before shaping the system around it.
Build for reliability
Clear boundaries, maintainable code, and careful integration matter in public services.
Keep improving
Observe how a system is used, then iterate with evidence and feedback.
