Hello! I’m Marcos Costa 👋

I’m a software developer with more than a decade of experience, passionate about building reliable, scalable, and developer-friendly software.

I’m the main maintainer and creator of KamiYomu, a Manga Reader and Download Platform focused on flexibility, extensibility, and long-term sustainability. KamiYomu powers multiple crawler agents, download workflows, and now a built-in reader — all designed to give users full control over their manga libraries and reading history.

Open source has always been a big part of my journey: learning from the community, contributing back, and maintaining projects that people can actually rely on.

Why sponsor? ❤️

Sponsoring my work helps me:

• Dedicate more time to maintaining and improving KamiYomu
• Add new features, crawler agents apis, and performance optimizations
• Improve documentation, stability, and long-term support
• Keep the project independent, open, and community-driven

KamiYomu has a growing roadmap, and sponsorship directly translates into more focus, faster iteration, and higher-quality releases.
