I'm a backend developer experienced with Node.js and Express, building clean, scalable architectures, well-structured APIs, and working with both SQL and NoSQL databases.

I like experimenting with new technologies, improving performance, and keeping things simple yet solid. This GitHub is also my personal lab — I use it to practice, test ideas, and even take technical notes from time to time.

• Languages: JavaScript (Node.js), TypeScript, SQL, C, Java
• Backend: Express, Clean Architecture
• Databases: PostgreSQL, MySQL, MongoDB (Mongoose)
• Infra: Docker, Apache
• Version Control: Git & GitHub (Issues, Projects, Drafts for notes)
• Frontend in progress: HTML, CSS, React ⚛️

• Building a clinic management system 🏥 with Node.js, Express & MySQL, applying Clean Architecture.
• Practicing unit testing with Jest.
• Learning React to become a more complete fullstack dev.
• Using GitHub not just for code, but also as a knowledge base for notes and experiments.

• Clean Architecture for scalable and maintainable projects
• SOLID principles, especially Single Responsibility Principle (SRP)
• DRY (Don’t Repeat Yourself) to reduce duplication and improve maintainability
• Repository Pattern for decoupling persistence from domain logic
• Domain-Driven Design (DDD) to model complex business domains

• Level up my frontend skills with React and PWAs.
• Explore GraphQL, Redis caching, and CI/CD pipelines.
• Deep dive into API security (XSS, CSRF, Helmet, rate limiting, etc.).
• Learn more about DDD and Node.js internals (streams, worker threads, clusters).

"This profile is a mix of serious projects and a nerdy playground for experiments and notes." 😅
