Iβm Marcel, a developer based in Poland π΅π±.
I build scalable web apps, clean APIs, and interactive experiences β and I also love creating mods/tools for Minecraft & Roblox.
- π Current Focus: performance-first full-stack apps + game ecosystem tooling
- π‘ Strengths: frontend architecture, backend logic, database design (TypeScript, Python, MySQL)
- π± Learning: system design, scalable patterns, reliability
- π§ Mindset: ship fast β refine until itβs clean
| Area | I like building |
|---|---|
| Frontend | component systems, clean UI, responsive layouts, performance tweaks |
| Backend | REST APIs, auth, validation, caching ideas, structured services |
| Databases | schemas that donβt hurt later, indexes, tidy queries |
| Game Modding | gameplay systems, utilities, automation, custom experiences |
| β Project | Description | Tech |
|---|---|---|
| π§± Nostalgia Project | A faithful recreation of the classic Minecraft website using modern web standards and clean styling. | HTML CSS JavaScript |
| π§ͺ m5rcode | A personal Python utility library for helpers, logic experiments, and data manipulation. | Python Data Structures |
β Ideas I can add next to these projects (to make them look βseriousβ)
- a clean README template (features, screenshots, install, roadmap)
- CI (lint/test) + formatting
- releases + changelog
- badges (license, stars, last commit)
- demo links / screenshots / gifs
