About
Tim Heineccius. Leadership responsibility at Telekom – and tools I build myself.
I advise businesses on automation and AI and work out of Bonn, Germany. For more than ten years I have held responsibility in commercial management at Deutsche Telekom – today part-time, alongside the consulting work. The tools I design for clients, I build myself.

Corporate experience
I still sit on the client side myself.
As Head of Commercial Management for Interconnection Fixed & Mobile at Deutsche Telekom, I have been responsible for commercial steering for many years, in an environment with high volumes and little room for error. I know how departments buy tools, how numbers have to be defended internally, and why in-house tooling projects fail. I keep this role deliberately – it is the reason my solutions get used day to day rather than just looking good in a presentation.

Delivery
Concept and code from one person.
I started because the tools I needed simply didn't exist. Excel macros turned into Python pipelines, pipelines into dashboards and web applications. Today the range runs from VBA through Python and modern web technologies to the controlled use of language models. For you that means: the person who understands your problem is the same person who builds the solution and hands it over.
- Excel/VBA, Python, TypeScript, SQL
- Web applications with databases and user roles
- AI automation with review steps and logging
Own product
Chunkaudio: self-built, live – and the first customers are paying.
Alongside corporate and client work I run a product of my own: Chunkaudio is a privacy-friendly audio splitter that runs entirely in the browser – no file ever leaves your machine. Designed and developed by me, publicly in use, and with its first paying customers. To me it's the best evidence that I don't just advise, I deliver.
Way of working
What you can expect from working together.
Honest rather than agreeable
If an automation isn't worth it, I say so – even if that makes the project smaller.
Your data, your code
You receive all sources and documentation that lets your team or another provider carry on.
Small steps, real data
Better a working version with your real cases early on than one big handover right at the end.
Publications & projects

Which process is costing you the most time right now?
Describe it briefly. You will get an honest view on whether automation is worth it – and if it is, a concrete quote. There is no hourly rate and no flat fee on this site: effort and price follow the task. Some projects are done in a few focused hours, others run over several phases.
