Executive Summary

Data scientist turned AI/ML leader (PhD Computer Science, MSc Artificial Intelligence) with five-plus years building and running multidisciplinary data science teams and a ~€1.3M platform budget inside a global corporation. I scaled a team from 8 to 16 data scientists, ML/software engineers and solution designers, and owned two production AI/ML platforms covering the full analytics journey from descriptive to predictive, delivering recurring savings above €3.5M.

I own the portfolio calls that follow — what to scale, what to hand over and what to shut down — alongside vendor strategy, demand intake and prioritisation across departments and European markets. I combine hands-on technical depth in ML, LLMs and agentic workflows, still shipping production code solo as co-founder of a live B2B SaaS platform, with life-sciences training in biochemistry, bioinformatics and biomedical machine learning on patient-derived data, and a track record of translating analytics into quantified business cases defended in front of senior leadership.

Platforms & Portfolio Decisions

Four initiatives that show how I run an AI portfolio: what gets built, what gets scaled, what gets handed over — and what gets shut down.

⚙️
Scaled & transferred
Computer Vision / MLOps Platform

Owned BASF's enterprise computer vision / MLOps platform, with a peer-reviewed library of 70 reusable templates and platform health tracked through active-user adoption and time saved per user. Once mature, I transferred it to its best-fit owner rather than holding on to it.

~€2M recurring savings · 70 templates · ~90% effort reduction for ~100 data scientists
📈
Reviewed & sunset
Self‑Service Forecasting Platform

Led a self-service time-series platform giving business users forecasting and decision support without a data scientist in the loop. After an ROI and adoption review, I recommended closing it — a platform I owned — and defended that call with numbers.

~€1.5M savings from the closure decision

Business case funded
GenAI Labelling Automation

Turned an image-labelling bottleneck into a quantified business case presented directly to VP stakeholders, and secured funding for GenAI-powered labelling automation. Ran a proof-of-concept of SIGMA AI and benchmarked competing tools to inform the build-vs-buy decision.

€560K secured · GenAI labelling plus five further innovation initiatives

Enterprise standard
Ontology & Knowledge Graph Programme

Owned BASF's Ontology Management Framework: the semantic foundation that makes heterogeneous enterprise data interoperable and machine-readable for AI and agentic systems, and the governance model that keeps it alive after launch.

20 bio-ontologies adopted as department standard · GOMO framework published

Experience

Leadership Approach

Three principles tested against a real portfolio, a real team and real investment decisions.

Build the bench, not just the backlog

Doubled the team through deliberate hiring, individual career paths and coaching of the managers who report into the role — including the hard conversations around underperformance rather than routing around them, because a team's ceiling is set by its weakest link.

Decide with evidence, and be willing to kill your own product

Recommended closing a platform I owned once the ROI and adoption data no longer supported it, and transferred another to a better-fit owner — both decisions defended with numbers in front of senior leadership.

Translate between worlds

Comfortable challenging model choices with ML engineers in the morning and framing the same problem as a business case for executives in the afternoon; this is where most analytics value is won or lost.

Entrepreneurship

Proyecto Vigía — Spain
Co-founder (50%) & Sole Developer
2026 – Present

vigiaprl.es ↗ Closed beta Access requires invitation credentials.

Co-founded and single-handedly designed and built, end to end, a B2B marketplace platform for a regulated Spanish services sector: Java/Spring Boot backend, React/TypeScript frontend, Keycloak-based identity and access management, geospatial PostgreSQL/PostGIS, document-processing pipeline with OCR, GDPR-compliant data handling, and Verifactu-compliant e-invoicing — from architecture through production deployment.

  • Took the platform from architecture to closed beta solo in ~3 months (June–September 2026), using AI-assisted development tooling (Claude Code) to accelerate delivery; now collecting structured feedback from the closed-beta cohort ahead of a planned public launch.
  • Conducted a self-led security review of the platform, identifying and remediating several vulnerabilities before the beta launch.
  • Optimised infrastructure cost by architecting on ARM-based cloud instances (Hetzner), balancing performance against a bootstrapped budget without compromising reliability.
  • Evaluating monetisation models — transaction-based commission versus a premium subscription tier — to shape the platform's go-to-market approach.
