01 — About

About

I'm a portfolio manager with about five years of experience designing, implementing, and overseeing systematic equity strategies in live capital environments. I built on my economics background (microeconomics, macroeconomics) and used Python to bring machine learning and automation into the process wherever they helped. I worked with established methods (LSTM, decision trees, bootstrapping), adapting them to my own data rather than building from scratch, and landed on two models: one for stock-by-stock return forecasting, one for portfolio construction.

My role progressed from research to portfolio-level responsibility within the same firm. Investing is a broad field, so I kept learning whatever it took to get better at it: risk management, data science, code, now generative AI. I contributed to the launch and management of three systematic equity AMCs, together raising about CHF 15M in their early fundraising phase, achieving approximately 24% aggregated net capital gain (capital-weighted, net of fees, through my January 2026 departure). I stayed disciplined through the stretches with no visible results yet and looked for another way through when the first approach didn't work.

The same thinking process shows up outside work too, in the personal projects I take on. I'm an investment professional first, and I use whatever tool actually gets the job done.

02 — My Path

My Path

A quick version of how I got here. Tap any point for the full story.

SICTIC — Startup Jury Scoring Framework

SICTIC · Private Equity, Venture Capital

  • [ PRIVATE EQUITY ]
  • [ VENTURE CAPITAL ]

Building the scoring framework behind SICTIC's startup jury process.

More details

231 due-diligence questions across four startup stages and eight industry sectors, still to be tested against 71 realistic use cases. Built using a multi-agent workflow: Hermes and MiniMax for research, Claude for orchestration and development, Codex for testing. Now extending it with the review team's jury-rating criteria.

Restaurant Operations Platform

Personal Project · Web Development, Operations

Turned a restaurant's ad-hoc, Excel-based profit tracking into a real web application.

More details

A waiter interface for tables and orders, plus a kitchen Telegram bot for stock tracking and demand forecasts. Built the requirements directly from the restaurant's own day-to-day floor and kitchen workflow, talking to the people who work there before automating any of it, using the same multi-agent workflow as SICTIC (Hermes and MiniMax for research, Claude for orchestration and development, Codex for testing). User accounts are live, and the platform now covers 74 staff-facing actions across ordering, stock, and kitchen operations.

This Website

Personal Project · Web Development, LLM Integration

Built from scratch, originally just to learn HTML and Git properly before taking on something bigger.

More details

It's since grown into a full interactive site with its own LLM-powered chat assistant, grounded strictly in real resume content. Visitors can ask questions, check job fit against a pasted job description, browse this timeline, download my CV or the conversation, and reach me through a contact form. Updated periodically since, rather than continuously, most recently through the same multi-agent workflow as my other projects (Hermes and MiniMax for research, Claude for orchestration and development, Codex for testing).

Research Analyst → Financial Analyst → Junior Portfolio Manager

HCP Asset Management · Zürich / Geneva, Switzerland

  • [ INVESTMENTS ]
  • [ DATA SCIENCE ]
  • [ PORTFOLIO RISK MANAGEMENT ]
  • [ PORTFOLIO MANAGEMENT ]

My master's thesis, on machine learning in asset pricing, became the reason I got hired. It was literally what my first conversation with my manager was about.

More details

Built a systematic equity fund from scratch: research, adapting established machine learning methods to the fund's process rather than building new ones, and a fully automated pipeline from research idea to live portfolio decisions across three AMCs, together raising about CHF 15M in their early fundraising phase, delivering ~24% aggregated net gain (through my January 2026 departure). I also presented results directly to institutional investors, translating the models into terms they could act on. My title changed twice along the way, but the work was one continuous build, start to finish. I pushed for the portfolio management title myself, because it matched what I was already doing.

CAS in Risk Management

University of Zürich · Zürich, Switzerland · GPA: 6/6

A few years into HCP, noticed a gap from inside the job: being a good investor needs a real risk lens too, not just business understanding.

More details

Covered fund risk, client risk, and business risk: risk governance, sustainability, and digital assets management. Led directly to the RiskON Challenge below.

RiskON Challenge — AI for Regulatory Compliance

Winner, Team RiskON @ University of Zürich · CRO, Compliance

RiskON 2024 Hackathon Challenge 3, proposed by Julius Bär.

More details

Worked with data scientists and mathematicians to build a proof-of-concept using Python and DistilBERT (a language model) that compares old and new banking regulations in English and German and flags substantive changes. Wrote the resulting chapter myself, published in a University of Zürich Department of Finance report. Read the paper ↗

MSc. Banking and Finance | Capital Markets & Data Science

Zürich University of Applied Sciences · Zürich, Switzerland

Convinced by then that finance needed a real technology layer, I looked for a program bridging finance and computer science, and found it here.

More details

Focused on quantitative investment strategies, machine learning, and risk management, leveraging data science techniques to optimize decision-making in capital markets.

Interests

Outside of finance and data science, I write poetry. It's a way to explore ideas that don't fit into numbers. Lately I've also been getting into AI more broadly, testing new tools, projects, and functionalities just to see what they can do.

Outside of work, I hike and explore new places, and recently got into fitness boxing. I read and cook.
