Projects

Poly+Uni Agenda

800+ users on launch day

Every public event from ETH and UZH student clubs and associations in one filterable agenda. Scrapers collect the club calendars, the site runs on my own VPS behind Caddy, and a pipeline turns new events into Instagram reels and posts automatically.

Also: ANKImporter, a small tool that imports flashcards into Anki, for example ones generated by an LLM.

Experience

Oct 2026 – now

Founder

Poly+Uni Agenda · polyuni.ch

  • Built and launched it alone, from the scrapers to the hosting.
  • Grew it through direct outreach to student clubs, an Instagram account with weekly carousels, and WhatsApp communities.
  • Testing a business model based on paid venue listings.
2023 – 2026

Freelance Developer & Consultant

ALPHOM (IT manager), Gconfiance and other Swiss SMEs

  • Analysed clients' workflows, found what could be automated and built it through to production use.
  • Marketing and business strategy for a seller of handmade lamps: market analysis, positioning, social media and newsletter.
  • Up to ~30 h/week alongside full-time studies. Selected work is described below without client names.
2020 – now

Audiovisual, Technical & Marketing Lead

Art de la Coopération · Fribourg

  • Led a small video team that produced a ~30-hour online course from planning to publication, including a near-automated recording studio.
  • Built and maintain the website and online learning platform; run newsletters, social media and SEO.
  • Built AI assistants: a course-script generator and a RAG assistant over the course material.

Client work · anonymised

Lead-monitoring pipeline

An n8n pipeline that watches Swiss companies for business signals in the news, scores each lead with an LLM, logs it to a spreadsheet and sends the team a daily email digest.

Drafting agents

LLM agents (LangChain) that take over the client's writing and drafting work, cutting it from about a day to 1–2 hours.

How I work

I take things end to end

Poly+Uni Agenda went from idea to 800+ users with me doing every part: code, hosting, outreach and social media.

I talk to clients, not just code

Three years of freelancing taught me to understand a business problem first and explain the technical options in plain words, in French, German or English.

I can lead a small team

At Art de la Coopération I planned and led the production of a 30-hour course, from scripts to the published videos.

I manage my own time

I passed the Swiss Federal Matura self-taught in one year, and worked up to 30 hours a week while studying full-time at ETH.

I think about the user and the market

I've done marketing strategy, newsletters, social media and SEO for clients and for my own projects, so I build things with someone in mind.

I learn across fields

Before computer science I did lab research in biology, and at ETH I've modelled economic and geopolitical systems. I pick up new domains fast.
