Building and operating the internal AI platform at Leonteq that teams use to ship production LLM applications and agents — the agent framework, RAG, on-prem model serving, and the governance and audit controls that let a regulated bank actually deploy them. Hands-on engineer and tech lead with 10+ years in financial technology, now driving the AI Foundry alongside the Sophis core platform team.
Hands-on AI platform and agent engineer at Leonteq, building and operating the AI Foundry — the internal platform teams use to ship production LLM applications and agents: agent frameworks, RAG, on-prem model serving, and the governance and audit controls a regulated bank needs before any of it reaches production. I also lead the Sophis core platform team and tech-lead the client-onboarding platform.
Over the past decade I've progressed from analyst to director, working across pricing/analytics, regulatory projects (MiFID II, SFTR, FRTB), and platform migrations. Now focused on bridging the gap between traditional fintech and AI-powered workflows — building on the platform, and helping other teams build on it too.
Building and operating the internal AI platform (the "AI Foundry") that teams use to ship production LLM applications and agents, and making sure it meets the audit and security requirements of a regulated financial institution. Three delivery streams run on it: the knowledge app, agent workflows built from business BAU requests, and agents embedded in existing internal applications. Hands-on in Python with my team; larger builds run with delivery partners.
Tech lead for the client-onboarding platform, automating compliance and regulatory workflows to reduce manual effort and onboarding risk.
Leading a team of 4 developers across Zürich and Lisbon. Handling incident resolution and operational risk analysis across time zones, coordinating with the Singapore and Amsterdam offices.
Implemented generic booking model for mirror booking, reducing client onboarding complexity. Built Grafana/Kibana monitoring. Key contributor to LIBOR migration.
Progressed through multiple roles focusing on automation, risk management, and regulatory compliance.
Focused on reporting automation and distributed system implementation. Automated creation of listed instruments via SmartCo integration.
Personal projects applying ML/AI and agent development to financial technology
Independent research into how LLMs deployed in Swiss financial institutions can be audited against FINMA supervisory expectations (Guidance 08/2024). Four threads: SP-Benchmark, a 56-question assessment of LLM comprehension of Swiss structured products scored by dual LLM judges; per-decision audit trails built from attribution graphs and token-level introspection; behavioural drift detection using sparse autoencoders; and a directional-error transcript scanner that probes model conduct under adversarial pressure.
An AI systems journal where topics and news are automatically collected by an agent, pushed to the repo via GitHub Actions, and trigger a fresh deployment, no manual writing involved. The interesting part is the architecture: agent → content extraction → commit → CI/CD → live site.
A self-improving AI trading system inspired by Karpathy's autoresearch: 8 AI agents compete on real Kraken Futures crypto perpetuals while the system improves them overnight. It mutates agent configs, tests variants on past data, and keeps the winners. Agents reflect on mistakes and build rules to avoid them. When problems persist, the system writes its own code fixes. The question: will agents that learn from their mistakes actually outperform simpler ones?
A live near-Earth asteroid explorer built around two AI systems: a tool-calling chat agent that drives a 3D solar-system scene, selecting asteroids, changing views, and running impact simulations, and an autonomous monitoring agent on a 4-hour cron using an advisor pattern, a low-cost Haiku executor that escalates higher-stakes calls to an Opus advisor, with persistent memory and email alerts. Data from NASA's NEO API.

Portfolio management and trend analysis system developed for Dufour Capital AG, combining financial mathematics with web technologies.
Agent & RAG platforms are the area I focus on most. To show how I approach these systems end to end, here's a generalized reference architecture I put together.
