Do your web applications need a robust, performant, and secure architecture?
Fullstack Software Engineer, I help companies and project owners design scalable web platforms. My approach goes beyond just writing code: I ensure your product is fast for your users (Next.js) and rock-solid on the server side (Java Spring Boot).
🎯 What I deliver for you:
- Fullstack Web Development: Creation of modern, fluid, and responsive interfaces coupled with a powerful backend.
- Microservices Architectures: Design of modular and scalable systems, ready to support your traffic growth.
- Security "By Design": Audits, integration of OWASP standards, and securing your data (JWT, OAuth2).
- Quality & Tests: Delivery of clean, tested (Selenium, JMeter), and analyzed (SonarQube) code to avoid technical debt.
🛠 My Technology Stack:
- Front-end: React.js, Next.js, Tailwind CSS, TypeScript.
- Back-end: Java (17/21), Spring Boot 3, REST API, GraphQL.
- Databases & DevOps: PostgreSQL, MySQL, Docker.
- Security: Cisco CyberOps Certified.
💡 My Working Method:
Transparent communication, strict adherence to deadlines, and proactive suggestions on technical choices. Whether it's creating a product from scratch (MVP) or strengthening an existing team, I adapt to your processes.
👉 Have a project in mind?
Send me a message to discuss it. I'm available for a free initial consultation to assess the technical feasibility of your needs.
