I build the systems behind modern growth.

I build operational systems for growing companies: from lead flow and ecommerce integrations to AI-powered workflows and custom internal platforms.

01 — The problem

  • Leads land in four different inboxes, none of them your CRM.
  • Your team is afraid to touch the code your founder vibe-coded last month.
  • Supplier data, inventory, pricing, and reporting all live in different systems.
  • Your AI workflows work beautifully — until one API silently changes.

02 — What I do

Four pillars, one operator.

01

GTM systems & lead flow

End-to-end: lead capture, scoring, routing, CRM integrations, billing, reporting, automations. The full machinery, built to actually run in production.

See the case study

02

Workflow automation & integrations

Supplier syncs, ingestion pipelines, AI workflows, APIs, and operational automations that reduce manual work and system fragmentation.

03

Internal tools & operational platforms

Custom internal systems for operations, reporting, task flows, lead management, billing, and business automation — built around how teams actually work.

04

Laravel architecture & cleanup

12+ years building and rescuing PHP/Laravel systems. Refactor what your AI-generated code can't scale. Make Horizon, queues, and integrations behave.

03 — Operator perspective

Built from the operator side, not the consultant chair.

I don't just build these systems for clients — I run them for my own businesses. Ecommerce, niche content, a SaaS, paid digital products, newsletters, internal tools. That means I understand both the infrastructure and the revenue.

  • Built and supported ecommerce operations for over a decade — Magento and custom Laravel.
  • Sold digital products and paid guides since 2014.
  • Run niche content businesses with my own SEO and writing.
  • Wrote and ran newsletter funnels that actually converted.
  • Built production automations for real operational workflows.
  • Built and operate my own SaaS (SitePerfector) — the same tool I deploy on client work.
  • Built custom operational tooling — for publishing, AI pipelines, scheduling, and daily workflows.

04 — Recent work

Three things I'm proud of right now.

2021 — present
Real-estate lead-gen, Belgium

A complete GTM platform for a growing real-estate company.

Built from zero: lead intake from 6+ sources, scoring, automated distribution to brokers, CRM sync, billing, reporting, lifecycle email. Now processes thousands of leads per month and runs the company's daily operations.

2014 — present
My own niche site

Industrial niche content business — paid guides and digital products.

Built and ran a niche industrial content business selling paid guides and digital products. Now reviving it with a proper content engine and technical SEO. Real laboratory for everything I sell.

2024 — present
My own SaaS

SitePerfector — operational content infrastructure.

A full content OS: strategy, planning, AI-assisted writing, rank tracking, site health. Originally built to support my own publishing and operational systems.

05 — Process

How I prefer to work.

  1. Phase 01

    Understand

    We start by understanding how your systems, workflows, and operational bottlenecks actually work today — not just how they're documented.

  2. Phase 02

    Plan

    A practical roadmap: priorities, tradeoffs, scope, and what actually matters now. No 80-page decks.

  3. Phase 03

    Build

    I build in small, visible iterations with async updates and direct access to the codebase from day one.

  4. Phase 04

    Maintain

    Some systems need ongoing refinement as the business evolves. I stay close where it makes sense.

06 — About

I'm Carsten. I build the system, then I run it.

Production Laravel since 2013. Magento years before that.

Over the years I've built lead-routing systems, ecommerce integrations, internal operational platforms, AI-powered workflows, and content infrastructure for both clients and my own projects.

I tend to work closely with a small number of operators and founders — usually on systems that have become business-critical.

Based in Penang, Malaysia. Mostly working async with teams in Europe.

07 — Writing

Notes from the workshop.

08 — Get in touch

Got a messy lead flow, or a codebase that's outgrown its founder?

If you want another operator looking at the system, tell me where the friction is — lead flow, integrations, AI workflows, scaling pain, internal tooling. Usually a short async exchange or a quick call to start. No pitch, no theatre.
