  3. FullStack Developer at Aether Solutions

    Responsible for the development of the frontend and backend of solutions such as Kudo or Yet. Using Nestjs, Nextjs, PostgreSQL, and Tailwind, I worked both independently and leading teams of 3 people. My key contributions in backend development include implementing Rate Limiting, Attribute-Based Access Control using dynamic permissions, real-time notifications and communication using WebSockets and query optimization for dynamic dashboards. On the frontend, I was responsible for designing a scalable architecture in Next.js using a feature-based structure to divide the dashboard into modules, along with authentication and data validation using Zod.

  7. Self-learning

    My focus was to learn the bases of web development and design. I learned HTML, CSS, JavaScript, React, and Tailwind. I also learned how to integrate the frontend with the backend using Express and MongoDB.

About Me

Since 2020 I began my journey as a software engineer, in the present I am a fullstack developer at the last year of my career (Systems Engineering).

The past year I delivered at my past company web applications using React and Angular, and backend services using Firebase. Improving the workflow and the delivery time of my team.

As a programmer, the 2 words that best defines me are adaptation and curiosity. My goal is to learn something new every day, and I am always looking for new challenges to improve my skills.
