about karol broda

hi, i'm karol broda, a developer from poland currently living near munich. i build tools that solve real problems without unnecessary complexity. from low-level systems in C to web applications with React, i focus on what actually works.

i specialize in systems programming and network tunneling solutions. i believe in creating software that developers actually want to use.

my philosophy: start simple, stay simple. boring technology that works beats the shiny new framework. if it takes more than 5 minutes to explain, it's probably too complex.

when i'm not coding, i'm probably reading about why someone rewrote their entire stack in rust, or actually touching grass (revolutionary concept, i know).

selected works

a blazingly fast network tunneling solution and proxy written in Go. funnel is the perfect alternative to ngrok for exposing localhost to the internet. ideal for webhook testing, API development, remote debugging, and sharing local development environments. supports secure tunneling, custom domains, and provides a simple tunneling solution without unnecessary complexity.

systems programming

a collection of low-level projects in C: DNS server, HTTP server, fuzzy matching with BK-trees, and custom data structures. built to understand how things actually work.

catalyst

a typesafe python SQL query builder. making database queries less painful, one type at a time. yes, even in python.

zubr

a modern desktop GUI for PostgreSQL. because sometimes you don't want to type 15 commands from muscle memory just to inspect a database.
