Currently working on a large-ish multitenant application. Coming soon.
In due time I will list some of my projects that I have worked on in the past, with code examples where applicable. Some of the things that I have created are:
- the fastest map of Iceland (my opinion) - using MapLibre and Mapbox Vector Tiles (MVT) to render all property zones of Iceland, a section of underground pipe infrastructure in Reykjavík, and the location of all active quarries of Iceland, data of which I had to specifically ask for.
- local to cloud file syncing engine written in Rust. As easy as the user downloading a client, they select a local folder and it would upload their files to a S3 compatible storage, specifically in this instance Supabase Storage.
- file sharing platform, aimed for B2B operations.
- equity options pricing model - this was my first sort of deep dive into C++, took me thousands of lines of code to make, handwritten matrix operations from scratch. Afterwards I rewrote it into Python into what was probably under 100 lines of code. Used something called Einstein summation that still blows my mind.

If you need a really simple website
As in a static website, perfect for showing off a local business, then send me an email.
Or if you need a more complicated project
Such as a business portal to centralize data with your customers in an efficient manner, I can also do that.
