Systematic growth through code & data.
My name is Hagen Müllershausen. As a Growth Engineer, I scale digital visibility and operational efficiency for companies. I combine SEO, SEA and AI automation into robust systems that remove technical bottlenecks and create measurable organic and paid ROI.
Disciplines
SEA
AI-supported campaign management, structured analytics and precise budget allocation for scalable paid impact.
Technical Systems
Custom software, AI-supported automation and clear process logic for stable, scalable B2B architectures.
FAQ
Frequently asked questions.
Do you handle projects completely on your own? +
Mostly yes. For Generative Engine Optimization, classic SEO and SEA, I usually handle projects independently to ensure technical precision. For larger SEO projects, I bring in my colleague Christopher. For AI automation projects, I work closely with my colleague Edgar, who supports parts of communication while I stay focused on programming and system architecture. I remain your direct point of contact in every project.
What kind of companies benefit most from working with you? +
My systems are primarily designed for larger B2B companies that need to optimize existing processes and scale beyond what standard software and conventional marketing setups can deliver. The strongest leverage appears where technical bottlenecks limit growth and custom systems create clear business impact.
Do you offer technical consulting for in-house teams? +
Yes. In GEO and classic SEO, I support teams with deep analysis and precise execution briefs. In AI workflows and automation, I usually start with technical feasibility and concept work, then move into implementation and delivery of the actual system.
Who are you and what qualifies you for this intersection? +
I started programming at the age of nine and have been focused on data-driven online marketing for several years. I also hold a Bachelor degree in Online Marketing and E-Commerce. My background combines software engineering with hands-on performance work at enterprise level, which allows me to turn growth strategy directly into scalable code.
Which technologies and stacks do you use? +
I work full stack. For automation and complex backend logic, Python is my primary tool, often with Django or Flask. For fast modern frontends, I use Astro or Next.js with React. On the data layer, I often use Supabase for scalable setups and SQLite for lean scenarios. I also integrate modern LLM interfaces and enterprise systems such as Pimcore.
How does collaboration usually start on a new project? +
We begin with a technical deep dive to identify bottlenecks and manual effort. Based on that, I provide an initial assessment, define scope and costs with full transparency, and then execute in clear milestones. Since strategy and implementation come from one source, execution is faster and avoids handoff friction.
