Danilo Manuel — Backend Developer
Java & Spring Boot · Londrina, BR · in the game since 2018
korzre@github:~$ cat about.txt
I'm a backend developer specialized in Java and Spring Boot,
with experience building APIs, distributed systems, and scalable
architectures across domains like fintech, healthcare, legal tech,
and institutional software.
I started in 2018 writing desktop apps in C#, went through a phase
of building games in Java, brief but formative, and eventually
found my place designing backend systems that are built to last.
I think in systems before I write a single line of code.
Architecture, data modeling, and flow design come first.
Then implementation follows with intention.
I'm also a fullstack practitioner. I deliver quality frontend
when needed, but backend is where I naturally gravitate.
I prototype interfaces in Figma or Penpot, build UIs with
React, Next.js and Astro, and ship desktop apps with Tauri.
I have a genuine interest in databases, not just SQL vs NoSQL,
but the real trade-offs: CAP theorem, consistency models,
partition tolerance, and when each tool earns its place.
