Minecraft Bedrock Developer • Marketplace Systems • TypeScript

A marketplace journey that started as a quest and turned into a career.

I started developing on the Minecraft Marketplace to fund a life-changing goal: crossing the distance between Brazil and the United States. That mission sharpened my discipline, turned curiosity into engineering, and built a career around gameplay systems, Bedrock architecture, and polished player experiences.

Origin Story

From playing worlds to building them

I'm Caio Costa, 23 years old, and games have been part of my life for as long as I can remember.

Growing up with the PS1, Xbox, and PC, video games were my first introduction to digital worlds. But my passion for building experiences goes far beyond a screen or a controller.

For the past 10 years, I've also been deeply immersed in tabletop roleplaying. Playing and running campaigns across Dungeons & Dragons (3.5e & 5e), Pathfinder, and Call of Cthulhu became my first real masterclass in game design. It taught me how to balance mechanics, design encounters, and keep a party engaged.

That love for systems and world-building naturally evolved into my career. Today, I work as a developer focused on Minecraft Bedrock and Marketplace content, writing TypeScript, building gameplay systems, and shaping projects that reach players globally.

For me, game development is where creativity, problem-solving, and personal meaning meet—whether I'm debugging complex entity systems or rolling a natural 20.

Questline

From first maps to flagship systems

This portfolio is structured like the adventure itself: early quests, rising complexity, bigger worlds, and the point where personal ambition turned into a professional standard.

Chapter I

The starting village

In Brazil, the Minecraft Marketplace was not just a platform. It was the way to create a future, prove value fast, and turn problem-solving into momentum.

Chapter II

The first contracts

Smaller Bedrock projects became practice grounds for balancing vanilla-feeling mechanics, production limits, and clean implementation under real delivery pressure.

Chapter III

The harder boss fights

Larger releases demanded scalable systems, maintainable TypeScript, custom behaviors, debugging discipline, and steady collaboration with artists and designers.

Chapter IV

The crossing

The goal was achieved: using Bedrock development to close the distance between two countries. That same drive still defines how I build, communicate, and ship.

Competences

What I bring to a team

The strongest pattern across my work is not just making features function. It is making systems hold together cleanly under real production pressure.

Gameplay systems architecture Scalable Bedrock systems designed to be maintainable instead of disposable.
TypeScript and Bedrock Scripting API Feature implementation, modular logic, entity behaviors, and production-minded debugging.
Marketplace delivery mindset A balance of creativity, performance, deadlines, and player-facing polish.
Cross-discipline collaboration Comfortable turning design intent into clean technical execution alongside artists and builders.

Professional snapshot

Computer Science background, years of Marketplace production, and a habit of treating Bedrock work like real software engineering instead of one-off scripting.

Studios and partners

Experience across Marketplace-focused teams including Kubo, Varuna, MrBeast-related work, Team Visionary, Cracked Studios, 5 Frame Studios, Refresh Studios, Logdotzip and more.

Current direction

I am actively looking for stronger long-term opportunities where technical depth, ownership, and clean systems are valued as much as speed.
