Hey, I'm Filip Zeman πŸ‘‹

Software Engineer | Systems, Data & Market Infrastructure

πŸ“ Pardubice, Czech Republic πŸ‡¨πŸ‡Ώ

β€œI code with both my mind and my heart, just like in the ring.” πŸ₯Š


πŸš€ About Me

I am a Software Engineer specializing in backend architecture, high-performance environments, and algorithmic logic. From engineering low-level networking frameworks in C++ and exploring OS development in Rust, to building complex data models for algorithmic trading, I thrive on solving complex technical challenges.

I don't just write code; I design systems with a focus on high throughput, cryptography, stability, and clean architecture. I value technical precision and projects that push the boundaries of what's possible.

πŸ”¬ Deep Tech & Open Source Projects

Here is a selection of my personal R&D projects, focusing on system-level performance, cryptography, and machine learning:

βš™οΈ Systems & Low-Level

RustikOS πŸ¦€ A small, experimental Operating System built from the ground up using Rust. Exploring memory management, kernels, and low-level architecture.

Cava ⚑ Experimental language/transpiler combining Java syntax with C++ performance. Designed to bridge the gap between developer ergonomics and raw execution speed.

Mango πŸ₯­ A fast, modern networking framework built in C++. Features a custom transport protocol (MUCP), dynamic routing, adaptive channels, and memory-efficient object serialization (MSON).

πŸ”’ Cryptography & Networks

DTTP πŸ” HTTPS-like encrypted protocol using ECDHE and AES-GCM. Built in pure Java without relying on standard TLS libraries for educational and deep cryptographic understanding.

🧠 Data & Machine Learning

Avocado πŸ₯‘ A modern Java-first machine learning library providing fast numerical computing, tensor operations, and efficient model building from scratch.

Market-Engine & Indicators πŸ“ˆ Core engines and algorithmic indicators built in Kotlin and Python for analyzing financial markets and executing trading strategies.

πŸŽ“ Leadership & Mentoring

DevSchool πŸ‘¨β€πŸ« An educational initiative I founded to teach young enthusiasts the fundamentals of OOP, Java, and Spring Boot architecture. Bridging the gap between beginners and production-ready code.
