Hi 👋, I'm Fellipe Leonardo

I'm a Software Engineer specializing in backend systems

I build across the full depth of the stack, from x86_64 Assembly and manual memory management in Rust, to scalable backend services with TypeScript, Go, Redis, and Docker, while mindful about trade-offs and architecture

Currently building with Go for high-concurrency backends

“I build to understand, and understand to build.”
― A reinterpretation of Richard Feynman's quote

Architecture & Backend
  • architecture-scaffolding: A tool for scaffolding projects using Hexagonal Architecture (or similar architectural styles), built with Godot
  • fastapi-uv-docker-boilerplate: A professional-grade starter for modern Python services. Orchestrates FastAPI, Redis, and Postgres using uv for blazing-fast dependency management and Docker Compose for reproducible environments
  • file-sharing-system-host: An exploration into networked systems, focusing on data transfer and server-side file management
Low-Level & Security
  • asymmetric-cryptography: A dive into security fundamentals. Implementation of cryptographic algorithms to understand the mathematical underpinnings of modern data protection in web
  • assembly-x86_64-nasm: Projects written in NASM to master CPU registers, system calls, and the inner workings of the x86_64 architecture, including a custom library. My "bare metal" experience
Systems & High-Performance
  • rust-http-server: An implementation of the HTTP protocol from scratch using Rust. Focused on understanding the TCP/IP stack and socket programming without high-level abstractions
  • brainduck-rs: A high-performance Brainfuck interpreter. It showcases Hexagonal Architecture in Rust, featuring a test suite and documented engineering trade-offs
  • gravity-simulator: A physics engine core written in C. Demonstrates manual memory management and the use of mathematical algorithms to solve real-time simulation challenges
Utilities & Tooling
  • architecture-scaffolding: A tool for scaffolding projects using Hexagonal Architecture (or similar architectural styles), built with Godot
  • sql-pseudocode-transpiler: A tool to parse and transform a custom pseudocode into SQL, JSON and xlsx (Excel), demonstrating skills in Lexical Analysis and Abstract Syntax Trees (AST)
  • youtube-downloader: A practical automation tool. Focused on handling external APIs, media streams, and providing a clean CLI/UI experience
  • godot-pomodoro: A productivity tool built with the Godot Engine. Highlights my versatility in learning different languages (DSLs; Godot) and UI/UX state management
