About me

Freelance AI/Systems and Palantir Foundry Developer, 7+ years. I build production AI systems and the data platforms they run on — usually for the same client. I like owning things end to end, data model to deployed UI, and shipping systems that get checked: evals, monitoring, data-quality gates.

Project history

Palantir Foundry Developer & Engineering Lead

The Original Body AG

Other

Brought in to build the client's Palantir Foundry instance from scratch - sole developer for the first months, then led the 4-person engineering team from 08/2025.
• Platform: integrated 10+ source systems (Zoom, Close, GoHighLevel, WhatsApp/WAHA) via a MariaDB webhook landing zone and a Python/PySpark transforms repo; built identity resolution as the company's single source of truth.
• Production AI/LLM system for customer support, shipped in one month: LLM ticket clustering secured by evaluation suites, automated response drafting with Automate monitors, vector/kNN search - 28 AI building blocks (3 AIP agents, 18 AIP-Logic functions, 4 monitors, 2 evaluation suites).
• Designed Ontology v2 - 29% of the company's ontology model, 31% of all productive datasets, 21% of all end-user apps.
• ~20 productive apps for sales, support and event teams; sole data enabler across three live sales summits, bulk-tagging 6,500+ leads per session.
• Onboarded a junior developer into Foundry within a month; 92% of colleagues' later datasets sit downstream of the ingestion and ontology layer I built.
The engagement concluded as planned in 04/2026; the client became insolvent shortly after and the Foundry instance was closed.

Founders Associate & IT

FLAGSHIP.BERLIN (formerly schoeneschiffe.berlin)

Transport & Logistics

10-50 team member

Turned a phone-and-paper boat-tour business into a digital ecosystem I designed and built end to end, running on ~20 EUR/month infrastructure with no vendor lock-in.
• AI-assisted charter CRM with auto-quoting (availability + opportunity cost to draft PDF quote and email): cut handling time from ~20 to ~4 min and response time from 24h+ to ~2h; associated with a self-reported +40% increase in closed deals.
• Self-built hotel booking portal (Cloudflare Workers, Hono, D1, real-time FareHarbor availability, QR onboarding, PDF invoicing) - 15 hotels onboarded.
• Grew the scheduled-line-trip channel from near zero: programmatically onboarded 4 booking-partner agents, 2 of them without an official API, via custom integration scripts.
• WhatsApp automation product (self-hosted WAHA, Cloudflare Workers, TypeScript, Neon Postgres, AI replies via Claude) - 35 own API routes, ~6,200 lines; later rebuilt at The Original Body.
• Fleet scheduling (Workers, React, D1, Claude SDK) with AI conflict detection before publish; FareHarbor/CalDAV slot-sync (Flask); multi-tenant jetty booking (FastAPI, PostgreSQL); marketing site (Next.js).
• Automated manual workflows across the business; worked directly with the CEO on positioning, partnerships and market entry.

Technical Project Lead

Stadtwerke Wedel

Energy, Water & Environment

Technical lead for the integration of powercloud (a cloud billing and operations platform for utilities) at a municipal energy provider, acting on the client's side.
• Acted as the client's sole technical authority opposite three external service providers - coordinating and challenging them to ensure correct, complete integration and that nothing superfluous was sold to the client (cost control and vendor governance).
• Was the only person carrying the integration technically on the client side; in-house specialists supplied technical prerequisites only.
• Primary link across all stakeholders; ran cross-functional meetings to align on technical objectives.
• Closed system gaps with custom solutions and third-party integrations, improving integration and process efficiency; coordinated training and post-implementation support for smooth software adoption.
• The platform went into operation; new customer contracts were being sold on the new infrastructure as of handover.

Palantir Foundry Data & Application Engineer

Axel Springer SE

Internet & IT

5000-10.000 team member

Drove the company-wide transition to Palantir Foundry: core data infrastructure, applications and user onboarding. Earned the Palantir Foundry Certified - Data Engineer credential during this engagement.
• Integrated 15+ source systems (Oracle Evolution, Snowflake, SAP, APIs, XML); maintained 100+ datasets; built ETL pipelines in Python/PySpark with health checks and data expectations.
• Migrated 30+ Looker reports and legacy SAS reporting pipelines; modeled 20+ core Ontology objects (including time-series); shipped 20+ custom Foundry applications for non-technical teams; reverse-engineered undocumented legacy SAP logic.
• Onboarded and upskilled 30+ Foundry users across roles and departments.
• Built up marketing units and marketing user handling; built a data-privacy system bringing the handling of personal data into GDPR compliance.
• A written client reference (Strategic Lead Data, Axel Springer SE, 2023) names PySpark and Java, calls out very good frontend skills (JavaScript, Node.js, React), rates the engagement "sehr gut" and confirms repeated re-engagement.

Innovation Prototyping

Kreuzwerker

Internet & IT

50-250 team member

Member (junior level) of a multi-disciplinary international team of coaches, designers and engineers validating product-market fit through user-centric design and rapid prototyping.
• Validated product ideas early, both technically and at the interface. Prototypes were deliberately not production-ready, built to test assumptions before committing to real development.
• Tech: Python, JavaScript, React, Framer, HTML/CSS; Design Thinking practices.

IT Solutions Consultant

schoeneschiffe.berlin and further SMB clients
Tailored IT solutions - sales, ERP, CRM and project-management systems - for small and medium-sized businesses, delivered end to end. Marks the start of continuous freelancing.
• Delivered systems end to end: requirements workshops, system selection, configuration, integration, training and support.
• Analyzed and automated manual workflows; maintained and troubleshot IT systems for ongoing reliability.
• Main client: schoeneschiffe.berlin (today FLAGSHIP.BERLIN), alongside a further engagement with a call centre in Spain. Partly overlapped with the final year of studies (through 08/2019).
