About

I engineer
certainty.

Husband. Father. CTO.
Born in '89, building on the web for over 15 years.
I believe that security is not a feeling – it's a deterministic state.

The Origin Story

From Bootstrap
to Boardroom.

My journey wasn't linear. It was practical.

In 2014, I co-founded Classy Vaper, an international e-commerce brand. We didn't just sell products; we built the entire supply chain and logistics platform ourselves. In 2017, after scaling to three markets, we successfully exited.

That taught me one thing: Software exists to solve business problems.

Since then, I've architected sovereign cloud platforms at IONOS for the German Government (ITZ Bund), built AI-driven content systems with Microsoft, and scaled complex SaaS architectures.

I've seen what happens when systems scale, and I've seen what happens when they break.

The Mission

Why I built
Kopexa.

Throughout my career, I noticed a dangerous pattern: Security and Compliance were treated as "paperwork."

Companies spent millions on PDFs, while their actual infrastructure remained vulnerable.

I founded Kopexa to fix this. We are redefining Governance, Risk, and Compliance (GRC). We don't ask "Did you do X?". We query the system state to prove it.

We use Policy-as-Code, Kubernetes, and Go to make compliance deterministic.

My goal isn't just to make you compliant. It's to give you the engineering resilience to sleep at night.

Off the Grid

The Human Side.

I am a husband and a father of two.

When you have a family, your definition of "risk" changes. You stop valuing "fast and breakable" and start valuing reliability, sustainability, and truth.

This mindset bleeds into my code. I build systems that are robust enough to run without me, so I can be present where it matters most: at home.

The Stack

Built on Giants.

I don't chase trends. I bet on technologies that provide stability and performance.

Core

Go, TypeScript, React

Infrastructure

Kubernetes, Docker, Terraform

Architecture

Hexagonal, Event-Driven (NATS), Cloud-Native

Security

Vault, ISO 27001 Implementation, Zero Trust

Stop guessing.
Start knowing.

Security is a solvable engineering problem. Let's fix it.
