Executive Summary

CTO with 20+ years building and operating production systems for SaaS and enterprise environments. I take responsibility for architecture decisions that determine whether systems survive real-world conditions. My focus is on stability, scale, and security—not rapid prototypes or feature velocity. I work with organizations facing production risk: systems under load, teams under pressure, and decisions that can't be reversed. Founder of Neyto, where I help companies stabilize and scale critical infrastructure.

Selected Impact

  • Stabilized production systems during 10× traffic growth without downtime
  • Reduced cloud infrastructure costs by ~40–50% through architecture optimization
  • Designed and implemented systems supporting 99.9%+ uptime across millions of transactions
  • Built CI/CD pipelines enabling zero-downtime deployments for mission-critical applications
  • Led engineering teams through high-risk production migrations without incidents
  • Established security practices preventing data breaches in high-value systems

How I Work

I take responsibility for:
  • Production reliability and system uptime
  • Architecture decisions with long-term consequences
  • Risk mitigation and security posture
  • Technical debt that threatens stability
I don't do:
  • Cheap MVPs that create technical debt
  • Feature factories without architectural oversight
  • Unsafe production shortcuts
  • Hype-driven technology choices
