How I Help

Technical Architecture
End-to-end architecture reviews, technology selection, and scalability planning. From monolith to microservices – built for your stage, not Silicon Valley's latest trend.

Practical AI integration that replaces headcount with intelligence. I've done it myself – 80% team reduction at AppMaster while maintaining output with AI-powered workflows.
Learn MoreCost Optimization
Infrastructure audits that cut cloud bills by 60-80%. Team restructuring that eliminates redundancy. Real savings from someone who runs a startup on $650/mo AWS.

Technical co-founders often feel alone. I serve as a sounding board, strategic partner, and technical therapist – because good decisions need a clear head.
