IT Director @ Comfy Holdings · $1B+ e-commerce · AWS · Microservices

I come in when the system is the constraint — and rebuild it.

$1B+ e-commerce Magento → microservices AWS · FinOps

Problems I solve

Sound familiar?

Legacy / Magento bottleneck

The monolith caps every roadmap decision.

AWS bill out of control

Spend grows faster than revenue. Nobody knows why.

Slow time-to-market

Competitors ship while you scope.

Dev team overloaded

Backlog grows. Business waits weeks.

How I help

Where I plug in.

Monolith → microservices

Move off Magento and legacy stacks without freezing the business.

Architecture for scale

Redesign so growth and peaks don't break the system.

AWS cost optimization

Recurring savings. Real ones. Not slideware.

AI workflow

Used where it removes friction. Not the headline.

Real experience

Led the migration off Magento at $1B+ scale.

  • Off the legacy platform
  • Scalability and team ownership unlocked
  • Faster releases, more flexibility
  • Architecture rebuilt for high-load growth

Example of approach

AI as a tool — not the product.

A non-developer shipped a production admin panel. Zero dev involvement. AI is one tool, not the headline.

Typical outcomes

What changes.

Faster releases

Days, not quarters.

Lower AWS bill

Comes down. Stays down.

Less dev dependency

Business stops waiting on engineering.

Scalable foundation

Growth and peaks don't break it.

Not a full review — we find the one thing to fix first. Architecture, AWS, modernization, scaling — bring whatever is hurting most.

  • Scaling bottlenecks — what's keeping the system from growing
  • Cost inefficiencies — where your AWS bill is leaking
  • Modernization paths — getting off the legacy platform safely
  • Quick wins — actionable inside 30 days

You leave with one specific action.
