My name is Antonis Geralis. I am an engineering student. I speak 🇬🇷 Greek (native), 🇺🇲 English and 🇩🇪 German. I code mostly in Nim. My programming interests include multithreading, fuzzing, traffic simulations, games and web-apps. I love solving hard problems and learning about Computer Science.

Some of the most interesting software projects I've authored are:

Name Description
drchaos A powerful and easy-to-use fuzzing framework in Nim for C/C++/Obj-C targets.
libfuzzer Thin interface for libFuzzer, an in-process, coverage-guided, evolutionary fuzzing engine.
eminim JSON serialization framework, works from a Stream directly to any type and back.
manu A linear algebra library in pure Nim. Supports constructing and manipulating real, dense matrices.
sync Useful synchronization primitives
bingo Binary serialization framework
goodluck A hackable template for creating small and fast games. Nim port
breakout Breakout game implemented using strict ECS architecture. Used as a testbed.
naylib Yet another raylib wrapper
jsonpak Packed ASTs for compact and efficient JSON representation, with JSON Pointer, JSON Patch support.
patgraph Efficient graph data structure library. The graph is a seq of nodes plus a seq of edges.
ssostrings Small String Optimized (SSO) string implementation
cowstrings Copy-On-Write string implementation according to nim-lang/RFCs#221
html2karax Converts static HTML to Karax.
neuralnet-examples Neural network examples
protocoled Interface macro
fusion/astdsl A DSL for convenient construction of Nim ASTs
looper For loop macros, zip, enumerate, collect (merged upstream)
