Hi there 👋, my name is Martin

I am a polyglot programmer and open source enthusiast, working as a consultant at Forse

I've built
- Mediator - a fast (close to 0 overhead) sourcegenerator-based mediator pattern implementation in .NET. Mostly MediatR-compatible, but faster
- Fast.PRNGs.NET - fast PRNG implementations (up to 2.5x faster than System.Random)
- simd-rand - SIMD implementations of common PRNGs in Rust 🦀 (for example Xoshiro256+ ~60 GiB/s u64 gen using AVX512 on my laptop, about 6x faster than non-vectorized)
- "building x in y" - experiments and learning about systems programming, programming languages, architectures and designs
  - Simulating football seasons using the Monte Carlo method in Rust - lots of SIMD and performance engineering
  - HTTP servers - experimenting with various techniques and architectures for performent HTTP servers: IO Uring, Linux, thread-per-core...
  - Calculation Engine - calculatione engine with a builder API for creating formulas while doing vectorized calculations over columns of data
Currently exploring Rust, Zig and Go

I strive to make simple, observable systems - employing mechanical sympathy to build efficient and reliable software.

Repository where I experiment and build various systems for learning purposes (mostly low-level)

bun

Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one

cake

Cake (C# Make) is a cross platform build automation system.

colorcodes

Small application for viewing and converting between different color code formats such as HEX, RGB and CMYK

coreclr

CoreCLR is the runtime for .NET Core. It includes the garbage collector, JIT compiler, primitive data types and low-level classes.

corefx

CoreFX is the foundational class libraries for .NET Core. It includes types for collections, file systems, console, JSON, XML, async and many others.
