Berke Kavak

Tailor-made AI agents and RAG systems that ship and stay in production.

Independent AI & agent consulting from Berlin, for teams across the EU and US, on your own cloud and data. Production ML and GenAI since 2018.

Services

Built on your own data and your own cloud. You own the result.

Agents and RAG

Assistants that answer from your documents, and agents that act inside your tools, with evaluations so you know when they break.

Semantic search

Hybrid retrieval and reranking, so people find the right answer instead of the right keyword.

Demand and sales forecasting

Forecasts wired into planning, not left in a notebook.

Churn and retention

Who is about to leave and who is worth keeping, delivered into the CRM.

Fraud and payment audit

Suspicious claims and payment errors flagged before the money goes out.

Pricing and segmentation

Micro segmentation that gives pricing teams a sharper view than the rate table.

Text and document processing

Classification and extraction for tickets, clinical notes and forms, at volume.

Tailor made AI video

Product and brand videos generated on my own GPUs, trained on your visual style.

About

I work at the intersection of applied research and delivery: comfortable reading the paper, but judged on whether the system runs in production and moves a business metric.

My master's research at Boğaziçi University on biomedical entity normalization with LLMs, across Spanish, English and German, was published at the BioCreative VIII SympTEMIST track. Before that, an industrial engineering and economics double major at Koç University taught me to treat ML problems as business problems first.

Based in Berlin. I work in English and Turkish, and speak good German.

Questions

Who do you work with?

Mid-sized companies and funded startups in the EU and US, usually a product or data team that needs a working system.

Which models and clouds?

Anthropic, OpenAI, Mistral or open-weight models, on AWS, Azure, GCP or Databricks. I don't resell any of them.

Fixed price or time and materials?

Scoped projects are fixed price. Ongoing work is a monthly retainer or a day rate.

Remote or on-site?

Remote from Berlin by default, on-site in Germany and Türkiye when it helps.

Can you sign an NDA first?

Yes, before the first call if you prefer.
