Hello,
I am Samuel.
After almost a decade as a self-employed personal trainer, I decided to take a new path into finance. I study at ZHAW in Winterthur and at SKEMA Business School in Paris to build professional knowledge of the highest degree in a field I'm passionate about.
My work
During my MSc in Banking and Finance I specialized in innovative technologies, which led me to start learning how to use large language models. These are some of my projects:
-
AI Programming Assistant
I taught an AI agent the strength and conditioning knowledge I have built over more than ten years. It pre-plans my clients' training sessions and keeps track of where each of them is in their training cycle. It became my programming assistant and now saves me around two hours a week. -
Personal Trainer Admin Assistant
I automated my entire admin process, from tracking memberships to sending invoices and planning the weekly sessions, with a connection to my work calendar and Gmail. Weekly admin time went from one to two hours down to ten minutes. -
BLG TeamHub Webapp
At BLG Sports we automated internal processes, including class signups coming from other platforms into ours, which had to be done manually before, and we built a web app for team absences. It saves the company countless hours and makes it run more efficiently. -
AI Second Brain
I use a system of Obsidian and Claude Code so an AI agent learns from sources I trust and uses those as its knowledge base instead of the open internet. It can make connections between knowledge points, like a real brain.
These skills are saving me hours each week while making the processes run more efficiently. I am eager to share the knowledge I have gained in a professional setting.

TeamHub
TeamHub is a web app I built for the team at my employer. It started with one question: what does a team actually open ten times a day? It became the single place that answers it. It was designed, built and reviewed with Claude Code, and it runs as a real app, not a slide deck.
What's in TeamHub
- My month: every coach and front desk person sees their own sessions and hours for the month. They tick the ones they can't make, and those go out for cover in one step.
- Open classes: the cover board. Anyone cleared for a session can answer “Want it” or “If needed”, and an admin confirms who takes it.
- Tell the team: after someone records an absence, TeamHub writes the WhatsApp message for the group chat. It's ready to copy, or opens straight in WhatsApp.
- Admin dashboard: one month at a time, showing who asked for what, what nobody has picked up yet, and what's already covered. Admins assign, decline or change cover in one click.
- Schedule: the whole week at a glance, with classes on top and front desk underneath. Open and covered sessions are marked.
- Team absences: every session handed over this month, grouped by person. Only admins see it.
- Front desk: the shift plan and hours, live. Staff log what they actually worked, and admins copy the monthly totals straight into accounting.

Personal Trainer Admin Assistant
This is the admin system I actually run my coaching business on. It reads my Google Calendar, checks which sessions happened last week, plans the next one for every client, drafts the invoices and the emails that go with them, and knows when a client's package is about to run out. Everything a self-employed trainer does on a Sunday evening, with one prompt.
What's in the zip
- Setup wizard: a one-time wizard that asks about you and your clients, then builds your workbook.
- Week Planner: checks last week against the calendar, then programs next week for every client.
- Invoice Generator: builds the invoice PDF from a client template and writes the cover email.
- Training Plan skill: the same one you can download on its own, wired into the weekly flow.
- Client roster template: swap in your own clients, packages and prices.
- README: how to install the skills in Claude and connect your calendar.
- Invoice template: a neutral one-page invoice with placeholders, ready to rebrand.
- User guide (PDF): setup and weekly use, step by step, no technical knowledge needed.
Free to use and adapt. If you build on it, I'd love to hear!
Training Plan Skill
A skill that teaches Claude the way I write 4-week strength cycles after a decade of coaching. Upload it to Claude, and a single prompt produces a plan I'd be happy to hand a client, once it has asked the questions a real coach would ask first.
What it asks you
- How many days a week you train, and which split you want
- Your experience level and how coordinated you are under load
- Whether you want a compact print version or a phone-friendly one
What you get
- A 4-week cycle with progression built in, week by week
- Blank fields to log sets and reps
- A print-ready PDF that opens on a phone or on paper
Everybody who jokingly asks me for a training plan gets sent this skill. Check it out!
AI Second Brain
I use a system of Obsidian and Claude Code so an AI agent learns from sources I trust and uses those as its knowledge base instead of the open internet. It can make connections between knowledge points, like a real brain.
