Designing systems that survive changing technologies.
AI models change.
Frameworks change.
Infrastructure evolves.
Well-designed systems remain.
About
I build systems where AI serves business logic — not the other way around.
- Knowledge Systems
- AI Automation
- Data Pipelines
- Event-Driven Architectures
- Production Infrastructure
Rather than chasing the newest framework, I focus on building systems that remain maintainable, scalable, and adaptable over time.

Engineering Philosophy
System Architecture
01
Task First
Systems should focus on completing business tasks, not showcasing AI capabilities.
02
Knowledge First
Data and knowledge outlive models. Structure your knowledge layer to survive any model change.
03
Business Logic In Code
Critical logic belongs in software, not prompts. Prompts are an interface, not a specification.
04
Replaceable AI
Any AI provider should be replaceable without redesigning the system.
05
Low Coupling
Every component should be replaceable independently.
Currently Building
Signal Intelligence Platform
Automated collection, filtering, analysis, and knowledge extraction from large-scale information streams.
Knowledge Infrastructure
Structured knowledge systems powered by PostgreSQL and vector search. Built to outlast any model.
AI-Assisted Decision Systems
Turning raw information into actionable intelligence through deterministic pipelines.
