Hi,

From raw chaos to decision-grade AI.

Production LLM pipelines, predictive systems and analytics that hold up under scrutiny, for research institutes and global organisations.

AI and Data Science Projects

  • Climate Evidence Engine 2026

    An AI research pipeline for the University of Zurich that reads sustainability reports, annual reports and SEC 10-K filings and turns them into structured, source-linked evidence.

    5,880 evidence rows · 392 STOXX 600 firms · 15 climate indicators

  • AI Early Warning Systems 2025

    Deep-learning and ML models that forecast tropical storms, droughts and floods for the UN Office for Disaster Risk Reduction, feeding a live investment observatory for disaster-risk financing. The work won an international award and was presented at GP2025 in Geneva.

    150+ countries in the governance taxonomy · 4 global data sources: GIRI, EM-DAT, World Bank, OECD CRS

  • Mathimatikos.xyz 2025

    An AI-native STEM reasoning engine. Multimodal OCR and RAG pipelines break a problem down into step-by-step, validated explanations with rendered maths and graphs, instead of one opaque answer. Queue-backed services, typed API contracts and usage metering keep it running in production.

    5 subjects: maths, statistics, finance, physics, CS · 3 input modes: typed, photo, handwriting

  • BetterPrompt 2025

    A Chrome extension and SaaS backend that rewrites rough input into expert-level prompts: intent analysis, academic/technical/creative classification, tone control and guided refinement, inserted straight into the tool you're already in. The backend routes between Gemini and Anthropic behind a secure proxy, with quota metering and subscriptions.

    8 AI tools supported · 4 prompt classes · secure key proxy, no keys in the browser

  • Humanitarian Dashboards 2024

    Production food-security, displacement and shock-monitoring pipelines for UN Women, feeding interactive maps and comparison tools that rank where support is needed first. Includes a documented Shock Exposure Index: component scoring, weighting, missing-data rules and interpretation limits.

    9 public data sources: WFP/HDX, IPC, WDI, FAOSTAT, UNHCR, OCHA FTS, ILOSTAT, IDMC/IOM, Findex

  • Power BI Case Studies 2025

    Independent Power BI work: three synthetic-data demonstrations styled after the kind of organisation each one imagines serving, plus one built on real, anonymized client data.

    4 live reports · audit compliance, scientific monitoring, talent analytics and maritime operations

Teaching & consulting

I tutor and train in statistics, econometrics, Power BI, Python and SQL, for students from LSE to Queen's Smith School of Business, and consult in data science, mathematics and finance.

Engineering rigour rooted in pure mathematics.

Mathematician by foundation, system architect by practice. I design AI systems that withstand real-world scrutiny: deterministic evaluations, verifiable data pipelines, and decision interfaces that non-technical leaders can act on. Read my M.Sc. thesis ↗ · Meet the mascot →
