epanet-js VS name-needed

At the start up I work at [0], we use an open source library I developed to run hydraulic models of water networks in JavaScript [1].

A hydraulic model may be between 1-10MB and the simulation results can end up being 100+MB of time series data.

Other vendors with proprietary engines have to scale up servers to run their simulation engineers and will store and serve up results from a database.

Having everything done locally means we only have to store a static file and offload the simulation to the client.

Because we've architected it this way our hosting costs are low and users generally have faster access to results (assuming they're running a moderately decent machine)

I'm a civil engineer and I wrote an open source library that compiled a C library to javascript for my own personal projects - epanet-js [1]

A water utility in Spain spun off a start up called Qatium [2] and they used my library as the engine of their simulations and asked me to join.

I created a handful of application around water engineering/modelling [1], plus an open source library to run the simulations in javascript [2].

A water utility in Spain spun off a start up to create a similar web based water modelling application and they used my open source library.

They approached me and I joined them and have been able to maintain the open source library as part of my role.

I work as a water engineer, specializing in building hydraulic models so water utilities can simulate their network.

A big part of that is calibrating them which can be time consuming, you look through hundreds of options. I create a few web based apps to help grind through these tasks but ultimately they were for my own use as a consultant to close projects quickly.

I did pull out the engine as its own open source library for other to use, and that ended up helping me get my current role where I can now maintain it and be paid at the same time.

I've built a few open source apps and few other little projects to help automate my workflow.

There are only a handful of providers of modelling software, most are commercial and one recently sold to Autodesk for $1B.

Not sure I'll convince the industry to change but I'm enjoying tinkering around and making my own small difference.

For my long term side project I just dump ideas into a barely organised backlog.md [^1]. After finishing a feature or taking a few months away, I normally dive back in by browsing this and choosing the next milestone.

It's worked well for a couple of years, and helps me keep the long term goals in mind.

It uses a custom static site generator because I needed to procrastinate somehow before starting the first post... Now it's nicely stable and punishing new posts is quick and easy

Location: Tallinn, Estonia (UK citizen intending to move there)

Remote: Willing to work partly remote but I require a sponsored visa to work in Estonia

Willing to relocate: Yes, to Tallinn :^)

Technologies: Rust, C, Python preferably, but C++ too. I enjoy low-level work focused on performance; see my toy OS, JVM implementation and game engine on my github profile.

I've written some pretty low-level OpenGL bindings in Rust, because the existing solutions are either too high level or over the top complexity wise.

At the time I only had experience with the OpenGL C api and didn't want to learn a totally different Rust abstraction or mix C/C++ libraries into a pure Rust project.

I've been alternating between two long term Rust projects, which seems to work in keeping the motivation up for both!

A x64 operating system: https://github.com/DomWilliams0/DomeOS

Ambitious to be sure, but after a year and a half I'm still consistently working on it, and still enjoying it!
