SECURITY · ARCHITECTURE · TECHNICAL LEADERSHIP

Systems that hold. Decisions that last.

Security, architecture and technical leadership for companies whose operation runs on systems. I know how the pieces fit, where they are fragile, and what to decide first.

FIXED PRICE · 2 WEEKS · WRITTEN VERDICT

Your operation already runs on systems. Most were never designed.

01 · THE PROBLEM
GLUE-01

Glue-work

Your best people spend their days re-typing data between tools that were never introduced to each other. That's not a staffing problem — it's a missing system.

SWVL-02

Swivel-chair operations

Order in one screen, status in a second, invoice in a third. Every swivel is a delay, an error budget, and a person who can never take a holiday.

KNOW-03

Knowledge that walks out the door

The one person who understands how the integration works is leaving in March, and none of it is written down. That isn't a staffing problem — it's a knowledge problem.

One method. Four stages. No theater.

02 · THE METHOD
D-01

Diagnose

Two weeks inside your operation. Where the hours go, where the errors breed, what the real constraint is — which is never what the brief said.

Output: written findings, quantified, with a verdict.
A-02

Architect

The target system on one page: components, flows, owners, failure modes. Boring technology chosen on purpose. Decisions documented with their reasoning.

Output: architecture + build plan you could shop around.
B-03

Build

Shipped in slices, each one live in production before the next begins. Your team operates slice one while slice two is built. No big-bang cutover, ever.

Output: a running system, documented and handed over.
R-04

Run

Monitored, maintained, evolved. The system earns its keep quarter after quarter — or you'll see exactly why in the numbers, because everything is measured.

Output: uptime, telemetry, and a quarterly systems review.

Three things I bring to the table.

03 · WHAT I DO
LEAD-01

Technical leadership

A senior technical voice for as many days as you need. Roadmap and priorities, build-or-buy and vendor decisions, guiding developers, and a straight answer when technology is on the management agenda.

ARCH-02

Architecture

How your ERP, webshop, invoicing, telephony and infrastructure fit together — on one page, with every decision written down and its reasoning kept. Knowledge that stays when people leave.

SEC-03

Security

Hardening, vulnerability management and access control for the systems you already run. Findings ranked by real risk and tracked until they are closed.

Security isn't a phase. It's how the system is built.

04 · SECURITY

Most breaches don't start with a genius attacker. They start with an unpatched server, a key left in a repository, a protocol nobody wrote down. I build security into the systems I design, and I review the ones you already run — with findings you can act on, not a PDF of scanner output.

SEC-01

Review & hardening

An audit of what you actually run: servers, containers, TLS, headers, secrets, access and dependencies. Every finding numbered, ranked by real risk, and tracked to closure — not filed and forgotten.

SEC-02

Vulnerability intelligence

My own vulnerability intelligence platform reads twenty public advisory feeds — NVD, CISA KEV, GitHub Advisories and more — every thirty minutes, and matches them against the software your systems really run. You hear about the CVE that matters, not the thousand that don't.

SEC-03

Patched in practice

I run around forty client sites on a platform I built and maintain. When a critical vulnerability lands, the whole fleet gets patched and verified — so the advice you get comes from doing it, not from a checklist.

Output: numbered findings, a remediation plan, and the fixes shipped — by the person who wrote the report.

05 · WHO YOU'RE DEALING WITH

You're not hiring an agency. You're getting a technical partner at the table.

I've spent my career inside other people's operations — print floors, warehouses, hardware labs, e-commerce back offices. The pattern never changes: the company isn't short on software, it's short on someone who knows how it all fits together.

No agency layers, no juniors learning on your budget. I lead every engagement myself: the person who diagnoses your operation is the person who makes the call and answers the phone when something breaks. Where a product needs a team, I lead the team.

Three ways in. One of them costs less than the problem costs you per week.

07 · START

No discovery calls. No proposals. A diagnostic, with a verdict.

Tell me about your operation. If it's a fit, we book the two-week diagnostic. If it isn't, I'll tell you that in the first email — and usually point you somewhere better.

STEP 01

You write

Three sentences about your operation and what's breaking. No forms longer than that deserve to exist.

STEP 02

I answer — with a verdict

Within two working days: fit or no fit, and why. No "let's hop on a call to explore synergies."

STEP 03

We diagnose

Two weeks, fixed price, written findings. Everything after that is your decision, made with real information.
