PIIRAMO OS
A personal digital space for tools, objects and focus. A modular application platform you can try in your browser.

From an idea
to something useful.
I'm Jesse. I am interested in how things work, and what could be built from them next.
PIIRAMO is where I turn ideas about software, data and hardware into things you can try. I look for solutions where technical thinking and a clear user experience meet.
ProfileA curious mind.
A curious mind.
A practical direction.
I think like an inventor: could this be done more simply? I am drawn to understanding data, making personal digital tools and finding new uses for existing devices.
My projects bring together ideas, interface design and technical development. I also use AI-assisted development tools. The work below shows what is currently available in each project.
This is a project-based CV: you can see the implementations, their possibilities and their limits. Education and employment history are not included in this profile.
Try what I mean.
Aurora Market Intelligence
A market-data workshop with a built-in ECB dataset. Explore currencies, compare risk, optimise a portfolio and try Monte Carlo simulations. You can also bring your own CSV.
Connecting perspectives.
Making data understandable
I am interested in the path from raw data to useful analysis. In Aurora, that means dataset processing, charts and computational experiments.
Tools for people
I want an interface to feel simple even when it supports many functions. PIIRAMO OS and Aurora are experiments in this approach.
Where software meets hardware
Electronics, servers and device reuse interest me. The S01 iPhone server node is a research project in development, not a finished product.

I am particularly interested in personal tools, practical uses for data and technical prototypes. Let's start with what you want to get working and find a suitable next step together.
