André Martins

🇧🇷 Estudante de Engenharia de Computação focado em desenvolvimento de sistemas, algoritmos e backend.
🇺🇸 Computer Engineering student focused on systems development, algorithms, and backend engineering.


👨‍💻 Sobre / About

🇧🇷
Desenvolvo ferramentas matemáticas e computacionais em ambientes web e CLI, com foco em desempenho, comportamento em tempo de execução e integração com bancos de dados.

Recentemente, venho desenvolvendo APIs backend em Java, explorando organização de sistemas, manipulação de dados e comunicação via HTTP, enquanto inicio estudos em desenvolvimento backend com PHP.

🇺🇸
I build mathematical and computational tools for web and CLI environments, focusing on performance, runtime behavior, and database integration.

More recently, I have been developing backend APIs in Java, exploring system design, data handling, and HTTP-based communication, while starting to explore backend development with PHP.


🛠️ No que trabalho / What I work on

🇧🇷

  • Desenvolvimento de APIs backend (Java)
  • Desenvolvimento backend com PHP (aprendizado e experimentação)
  • Ferramentas matemáticas e estatísticas (Web e CLI)
  • Implementação de algoritmos (busca, ordenação, métodos numéricos)
  • Análise comparativa de runtime e performance entre linguagens
  • Computação de propósito geral em GPUs usando CUDA e TensorFlow.
  • Integração com bancos de dados relacionais (SQLite, PostgreSQL)
  • Manipulação de dados estruturados (JSON)

🇺🇸

  • Backend API development (Java)
  • Backend development with PHP (learning and experimentation)
  • Mathematical and statistical tools (Web and CLI)
  • Algorithm implementation (search, sorting, numerical methods)
  • Runtime and performance benchmarking across different languages
  • General-purpose GPU computing using CUDA and TensorFlow
  • Integration with relational databases (SQLite, PostgreSQL)
  • Structured data handling (JSON)

🎯 Abordagem / Approach

🇧🇷
Prefiro entender os fundamentos em vez de depender puramente de abstrações.

Meus projetos exploram como sistemas funcionam internamente — desde modelos matemáticos até execução de código, incluindo acesso a arquivos, manipulação de memória e interação com bancos de dados via SQL.

🇺🇸
I prefer understanding fundamentals rather than relying purely on abstractions.

My projects focus on how systems work internally — from mathematical models to code execution, including file I/O, memory behavior, and SQL-based database interaction.
