Currently Exploring

  • AI agents for business and engineering workflows
  • AI-assisted software development
  • Practical LLM applications
  • System architecture and scalability
  • Engineering team effectiveness
  • Data-driven product development
  • Building small SaaS products

Building

I enjoy taking ideas from:

Problem → Prototype → MVP → Production

Some things I've worked on include:

  • Finance and ERP-style backoffice systems
  • SaaS products
  • AI proxy and LLM gateway infrastructure
  • Database backup, migration, and validation tooling
  • RAG systems over internal data
  • Internal engineering tools
  • Mobile applications
  • Developer tools

Engineering Philosophy

Good engineering is not about using the most technology. It's about solving the right problem with the right amount of technology.

I generally prefer Over
Simple systems Unnecessary complexity
Automation Repetitive work
Observable systems "It should be fine"
Small iterations Big-bang releases
Data-driven decisions Assumptions
Production usefulness Technical perfection
Tools that solve problems Tools that look impressive

Engineering Leadership

I also work on the people and process side of engineering:

  • Engineering team structure
  • Technical direction
  • System design reviews
  • Developer mentoring
  • Delivery planning
  • Engineering metrics
  • AI capability development
  • Improving engineering workflows
  • Turning business requirements into technical execution
