What I’m building.

Welcome to my personal projects!!

I’m Jonas, a strategy consultant from Hamburg, Germany. I enjoy spending my free time building solutions which address whatever problems I face in my day to day life.

Project library

Current projects, all at different stages.

Each project addresses a real pain-point I was facing. I built, researched, designed and engineered all of them myself (with great assistance by Claude), during the night or on weekends. Currently, not all projects have public sites on their own, hence the library here. If you are interested in any of the projects, please reach out via LinkedIn.

01Online

Aurealis Intelligence, an equity research terminal.

Aurealis produces institutional-style research on any listed company: an eleven-section report carrying a rating, a price target and cited evidence, assembled in roughly three minutes. Its Deep Research mode plans falsifiable hypotheses, investigates them in parallel across filings, news and market data, then turns an adversarial critic on its own conclusions before publishing anything.

The platform is finished and running. Its commercial launch was abandoned, as taking it to market would have created a compliance conflict with my employer, so Aurealis now stands as a completed engineering project, which I use myself almost daily, rather than a business. For reference, the website is still live.

An eleven-section equity research report on Adobe, opening with a BUY rating, a $322.70 price target and a 29 per cent upside, followed by a snapshot of the fundamentals.
The Aurealis overview: today's movers, a week-ahead earnings calendar, a 128-ticker watchlist with ratings, and a recession radar reading 25 per cent.
A per-ticker workstation showing a one-year price chart for Adobe with key metrics, a 52-week range, earnings history and analyst consensus.
Twelve sector cards, each with a sparkline, its constituent holdings and a breadth bar showing how many members advanced or declined.
Sixteen colour-coded theme cards covering artificial intelligence, critical minerals, defence, nuclear, quantum, robotics and more, each labelled with its number of tiers.
The artificial intelligence value chain broken into tiers from compute and silicon through foundry, memory, packaging, semicap and networking, every tier mapped to live tickers.

02In development

Core Fitness, a data-driven health platform.

The idea for Core emerged, as I track my fitness and health across multiple platforms - Whoop, Strava, and Hevy - additionally I regularly get my blood tests done. Whilst it is possible to track everything individually, I was yearning for a more data-driven, consolidated picture. Hence I built Core. It combines all my Strava, Hevy, and Whoop data simply via API. Core allows me to see cross-domain data relationships such as the impact of my lifts on RHR or HRV data, as well as sleep.

Core is currently in development and not yet public. Right now I am working on integrating an AI coach as well as exploring more options for data analysis.

Aerobic efficiency gain uncovered and quantified by putting all data into context, rather than looking at individual metrics in isolation.
Chronic and acute training load plotted together over ninety days, with a form curve below shading green where fitness exceeds fatigue and amber where it does not.
Front and back anatomical silhouettes with each trained muscle group filled according to a six-step strength tier ramp from wood through to platinum, and the untrained groups left slate grey.
A scatter of 353 days plotting training strain against next-day recovery, coloured by recovery zone, with three fitted regression lines.
Heart-rate variability over ninety days against a shaded personal baseline band, with the baseline rising sixteen per cent.
Resting heart rate over ninety days against the same baseline band, trending downward from the low fifties.
A month grid for July 2026 where each day carries a recovery-coloured tick, a strain figure and session pills labelled with their characteristic number, closing with a weekly summary column.
A cardiovascular and lipid panel where each marker sits on a range pip showing its value against a cited optimal window.

The next one, not ready to show.

In progress, but not public yet. This card will describe it once there is something to point at.

About

Three notes on how these get built.

Research, design, engineering and operation all happen in the same place. Over the past year I have established a solid library of Skills and MCP servers, which I leverage to build and operate my projects. No matter the project, I always follow a set of key principles to help execute these projects fast as my free time is scarce.

01

A problem-driven, solid idea.

I start with the problem. Aurealis and Core both address issues I faced in my daily life, and now simplify my workflows and save me time each day.

02

A unified and simple UI/UX.

I am no designer, and I carry that with me in all my projects. Few colors, clean design, and focus on data and impact visualization.

03

Lean, but effective.

As much as I'd love to just throw an Opus 5 API at all my issues, I build the systems logic-based and token-efficient. For Aurealis I built a custom evaluation framework to ensure accurate and replicable results.

Where to find me.

I created this page to document and showcase my projects. Since I am not actively pushing any of my projects to market due to constraints with my job, I'd still love to put it out there. If you're interested to chat, please reach out!!
