I design and develop digital products: web apps, services, APIs, data products, dashboards and AI workflows. From a fuzzy brief to a usable first version — hands-on, in code.
I combine product thinking with hands-on delivery — structuring requirements, designing solutions and building them myself.
I can structure projects and implement them technically — from product logic and data model to UI and backend.

Starting point, my contribution, outcome — what typical collaboration looks like.
A complex manual process needed to become a usable self-service interface.
Structured product logic, defined core entities & workflows, designed and built frontend, backend and API structure.
Clearer, usable platform logic with better usability and clean data structures as a basis to scale.
Several systems needed to be connected via APIs, mappings and status logic.
Analyzed interfaces, defined data flows, built mapping & status models, implemented integration logic.
More stable system communication, clearer responsibilities and traceable data flows.
Data from various sources needed to be merged and made usable for decisions.
Designed data models, built import & transformation logic, developed reporting structures and KPIs.
Usable data base for dashboards, reports, operational steering and further product features.
Unstructured content needed to be processed, classified and made usable automatically.
Developed data flows, labeling logic, backend structure and AI-powered enrichment.
Technical prototype with data pipeline, AI analysis and usable product logic.
Information from external sources needed to be collected and processed regularly.
Scraping / API import processes, data validation, transformation and handover to reporting & product components.
Less manual work, better data availability and repeatable processes.
Beyond client work — a shipped product and a company I'm directly involved in.
Don't talk about solutions forever — build a first working version fast, learn from it and improve it iteratively.

Day rate based on project type, responsibility and duration — for clearly scoped projects also as a fixed or package price.
Web apps, services, APIs, automations or dashboards.
Data products, scraping, reporting, DWH or AI workflow projects.
MVP or app projects with product & delivery responsibility.
Strategic-technical product guidance with hands-on delivery.
Remote-first, on-site in Berlin when needed. Options: scoped delivery packages, MVP development or part-time engagement over weeks to months — also within existing engineering teams.
