What you get after every call

Structured Requirements

User stories with acceptance criteria, not wall-of-text notes. Your developers can start building immediately.

Architecture Rationale

Tech stack recommendation with clear reasoning. Python, TypeScript, FastAPI, LangGraph, vector databases — I know what works and what doesn't.

Risk Flags

I tell clients when their architecture idea won't work — clearly, without losing the relationship. Open questions that need a decision before development starts.

2-Hour Delivery

Everything documented and in your shared workspace within 2 hours of the call. Not days. Not "I'll send it over soon."

How it works

1

Pay & Book

Select a tier, pay securely via Stripe, and pick a time slot that works for all parties.

2

Brief me

Share context: who's the client, what's the project, what do you need clarity on? 5 minutes of prep saves 30 minutes on the call.

3

I join the call

I ask the technical questions, steer toward decisions, and make sure nothing stays ambiguous.

4

You get the spec

Structured requirements in your workspace within 2 hours. Your team builds. No back-and-forth.

Technical depth

AI & Machine Learning

LLM integration, LoRA fine-tuning, RAG pipelines, LangGraph agents, vector databases, Fireworks AI, MLX. Not buzzwords — production experience.

Full-Stack Development

Python (FastAPI), TypeScript, React, Next.js. From API design to frontend. I know what's realistic to build and what's scope creep.

Infrastructure & DevOps

Kubernetes, Helm, Docker, GitOps, self-hosted platforms. 20+ years of datacenter and cloud operations.

IoT & Smart Buildings

KNX, Modbus, ThingsBoard, sensor networks. If your project touches physical infrastructure, I've done it.

Frequently asked questions

Do you sign NDAs?
Yes. Standard mutual NDA before the first call. I can use yours or provide mine.
What time zones do you cover?
I'm based in Germany (CET) but regularly take calls across all time zones. Early morning or late evening is no problem.
What languages do you work in?
English and German. Both fluently, both professionally.
What if the client changes requirements after the call?
First revision of the requirement document is included. Additional calls are billed at the same rate.
Can you also build the project?
Yes. If we agree on the scope during the discovery call, I can provide a development proposal separately. But consulting and development are kept separate — no conflicts of interest.
What's the difference to a regular project manager?
I'm a senior engineer, not a PM. I understand the code, the architecture, and the trade-offs. When I write a requirement, a developer can build from it without guessing.
