Why Your Kubernetes Setup Is Burning Money
Most startups don't need Kubernetes. Here's how to know if you're one of them.

I Build MVPs That Don't Collapse When You Scale
Most startups rebuild their entire tech stack after product-market fit. Mine don't.
I architect production systems that survive your first 10,000 users—then scale to your first million without a rewrite.
Fractional CTO & Technical Architect for venture-backed founders who can't afford to get infrastructure wrong.

Who I Am and
Why I Do This
I've been the technical person in the room for 15 years.
I've built systems that processed billions in transactions. I've debugged production disasters at 3am. I've walked into inherited codebases that made me question my career choices. I've hired engineers, fired engineers, and trained engineers who became better than me at specific things.
Most technical problems aren't technical. They're communication problems disguised as architecture decisions. Founders don't need a CTO who speaks in jargon. They need someone who can translate "our PostgreSQL connection pool is saturating" into "we can't handle Black Friday traffic and it'll cost us $200K in lost sales."
My unfair advantage: I've seen your exact problem 40 times before.
15+ Years
Building, breaking, and fixing systems at startups, enterprises, and everything in between
40+ Projects
From zero-to-one MVPs to scaling systems serving millions of users
Pattern Recognition
I can tell you the fix before looking at the code—I've debugged it before
I don't work with everyone. I only work with founders who have secured funding or revenue, value speed and quality over cheap, are coachable, and actually plan to implement recommendations.

1,000+ simultaneous property evaluations
AI pricing accuracy
94% within 5% of market value
Broker efficiency
60% reduction in property evaluation time
System uptime
99.8% during first 6 months
"The queue automation and AI integration transformed how our brokers work. What used to take hours now happens in seconds."

These are real engagements with real outcomes. Your results will vary based on your specific situation.
Three Ways to Work With Me
Choose Based on Where You Are
Not what you think you need.
🔍
Technical Diagnostic & System Blueprint
A 2-week deep-dive into your existing system or planned architecture. You get a brutally honest assessment of what is working, what is broken, and what will break when you scale.
Best For
Pre-Series A startups with working prototypes, founders inheriting code from departed contractors, technical teams stuck in analysis paralysis, or investors conducting technical diligence.
50+ page technical audit
Architecture recommendations
Risk assessment matrix
Cost projections at scale
🚀
Fractional CTO Executive Leadership
I become your acting CTO for 3-6 months. Not advisory—actual execution. I make technical decisions, manage engineers, architect systems, and ship product.
Best For
Funded startups (Seed to Series A) without a technical co-founder, companies between CTOs, non-technical founders building technical products, or teams that need to ship in 90 days.
Own technical strategy
Build/rebuild infrastructure
Manage engineering teams
Weekly executive reporting
🧭
Executive Advisory & Mentorship
Ongoing strategic guidance for technical leaders who need a sounding board. Think of it as having a CTO coach who has seen your problems 40 times before.
Best For
First-time CTOs at growing startups, technical founders scaling beyond their experience, engineering leaders navigating org changes, or teams post-Series A building out leadership.
Bi-weekly strategy sessions
Architecture consultation
Hiring support
48hr async response time
Not sure which fits? Book a 30-minute fit call (free) — I will recommend the right engagement. No sales pitch.
