Description

I am a Senior Software Engineer with over 5 years of experience transforming business requirements into robust, scalable, and high-performance digital products. My focus is not just on writing code, but on designing strategic technical solutions that ensure the long-term maintainability and growth of each project.

How can I help you?

High-level Backend Development: Specialist in the Node.js ecosystem with NestJS, designing efficient, secure, and mass-growth-ready microservices architectures.

Modern User Interfaces: Development of SPA and Microfrontend applications with ReactJS and Next.js, prioritizing load speed, user experience (UX), and code modularity.

Data and Performance Engineering: Advanced optimization of SQL Server databases through schema design, Stored Procedures, and complex triggers to delegate critical logic and improve system performance.

Distributed and Real-Time Systems: Implementation of asynchronous communication using Apache Kafka and bidirectional data streams with WebSockets.

Infrastructure and Deployment: Environment management using Docker and administration on Linux systems, ensuring parity between development and production.

Why work with me?

My work methodology is based on technical excellence and transparency. I rigorously apply SOLID principles, Clean Code, and engineering best practices to deliver software that not only works but is easy to evolve.

I have extensive experience working under agile methodologies (Scrum), which allows me to quickly integrate into existing teams or lead the technical development of new products, always maintaining clear communication focused on client objectives.

If you are looking for a technical partner who brings strategic vision and commitment to quality, let's talk about your project.
