The builder behind the work

Phillip Janzen — founder of Outstanding Marketing.

Every project in this portfolio was architected and built hands-on. I split my time between the codebase and the ad account — which is exactly why the systems actually ship and keep running.

That means event-driven API integrations and automation in Python, production systems like a German-market CRM, web engineering in Next.js, and the paid acquisition and lifecycle automation that sit on top. One person accountable for the whole build — not a chain of handoffs.

Work spans health & supplements, subscription e-commerce, energy sales and high-ticket coaching across DACH & international brands. If you can describe the system you need, I can build it — and hand it over documented and owned by you.

How We Work

How we build it.

The same six-step process behind every project in this portfolio — from first call to a documented system you fully own.

Discover

We map your stack, data and goals — and pin down exactly what the system needs to do before any build starts.

Architect

A clear technical plan: data flows, integrations, edge cases and the stack — so there are no surprises mid-build.

Build

We ship it properly — typed, tested, idempotent and observable. Code you actually own, not a black box.

Integrate

Connected to your real tools with retries, rate-limit handling and alerts, so it survives flaky third-party APIs.

Verify

We test against real data and edge cases, then monitor in production — logging, audit trails and failure alerts.

Hand over

Documentation, a walkthrough and a system that runs itself — plus support when you want to extend it.

Clients

What clients say.

“He's the rare person who can build the thing. Our integrations, our store, our dashboards — all of it just works now, with no one touching it manually.”

Founder

E-Commerce Operation

“We needed software no off-the-shelf tool could give us. He delivered a production system that actually shipped — and kept running.”

Operations Lead

Auto-Parts Reseller

“The CRM and landing pages made our whole solar operation finally make sense — clear, fast, and exactly on brand for the German market.”

Managing Director

Solar Energy · DACH

“From the storefront to the campaign launch, every piece was custom and considered. It looks and performs like a premium brand.”
