Independent consulting engineer

Biogas that pays off. Plants engineered right. AI that works for you.

As an independent engineer, I support plant operators, industrial firms and businesses: biogas economics, plant engineering and practical AI adoption.

My approach

A clear process, on site or remote — from the first conversation to implementation

  1. Step 1

    Understand

    Discussion and review of documents and data from your plant or company to clarify goals and constraints.

  2. Step 2

    Analyse

    Calculations, planning and scenarios that put numbers on the options before any investment.

  3. Step 3

    Recommend

    A prioritised action plan with costs and benefits, written for decision-makers, banks and investors.

  4. Step 4

    Support

    Follow-through on implementation, presentations to stakeholders and knowledge transfer to your team.

About

A project engineer at the crossroads of technology, energy and AI

In 2021–2022 I worked at Biogas Reichardtswerben GmbH (process monitoring and determination of the CO2 footprint). From June 2022 to March 2026 I worked as a project engineer at EPC Engineering & Technologies GmbH in Arnstadt: basic and detail engineering of plant systems with AVEVA E3D, pipe supports, simplified stress analyses and assembly and fabrication documents — for chemicals, pharma, polymers, biotechnology and renewable energy.

Today I combine that engineering foundation with my biogas experience: economic consulting for biogas plants and hands-on support for businesses adopting AI — independent, and from a single point of contact.
