Your infrastructurebecomes an advantage,not a brake.

I help fast-growing companies design, build and hold their platform, from cloud architecture to a shipped product. End to end, or just the step that is blocking.

Who I work with

Technical teams that can no longer afford mistakes.

The moment the improvised early infrastructure becomes a risk. That is where I am most useful.

01
Growing scale-ups

The product works, traffic is climbing, and the early infra no longer keeps up. You need to scale without rewriting everything.

Scaling
02
SaaS companies

A platform that must stay up, deploy without stress, and stay profitable as it grows.

Reliability & cost
03
Engineering leaders

A CTO or lead who wants a solid outside read before committing to a rebuild, a migration or a budget.

Audit & trade-offs
04
Founders with a product to build

A clear scope but no engineering team to carry it. I design and ship the product, from the first line to production.

End-to-end build
Two tracks

From architecture to a shipped product.

Take the whole thing, or just the step that is blocking. Either way, I do the work.

Cloud & infrastructure
Your platform exists. I make it solid and cost-effective.

AWS architecture, bill reduction, reliable releases, scaling without breaking what runs.

02Migration & gradual rebuild
03CI/CD, monitoring, backups
Product development
Your product is still to build. I ship it end to end.

A complete SaaS: scoping, architecture, development, launch. One person accountable for the result, not a chain of vendors.

Why it is urgent

Infrastructure you do not control costs you three times: money, speed, confidence.

01
The bill drifts silently

Oversized resources, forgotten environments, peripheral costs nobody watches. Half the spend is often pure waste.

02
Every deploy is a risk

Without a reproducible pipeline or a rollback, shipping becomes an event people dread. The team slows itself down, and the product with it.

03
Decisions are made blind

No metrics, no alerts, no tested backup. You find out from an unhappy customer, at the worst possible moment.

The method

Understand, measure, fix, hand over.

No three-quarter rebuild announcement. We move in short steps, each delivering a measurable result, and your teams keep the controls at the end.

01
Audit

Two weeks to map what exists: architecture, costs, risks. You leave with a quantified picture, readable by engineers and executives alike.

02
Plan

A path prioritised by impact and effort. What we do first, what we knowingly defer, and why. Every step has an expected result.

03
Execution

I get my hands in it, with your team. Not recommendations for someone else to apply: work shipped to production, reviewed and measured.

04
Handover

Documentation, guardrails, training. The goal is that you no longer need me on the same subject.

Why it will work

I build my own products. I live the same constraints you do.

I don’t sell slides. I run Stralya, where my team keeps scale-ups’ AWS infrastructure running, and I’m building Klickbee, our own product. Every recommendation I make, I apply at home first.

Operator, not theorist

I built, scaled and then sold my own business before advising anyone else.

Measured results

Bill halved, incident-free deploys, measured recovery time. Numbers, not impressions.

Limited engagement, lasting impact

I take on few engagements at a time, and I always aim for my own exit rather than dependency.

Writing

What I have learned, written down.
