As a full-time developer I was involved in two major projects: one built with Ruby on Rails and another utilizing Python (FastAPI) and React. These projects provided me with a diverse range of challenges and opportunities to implement best practices across different technologies. The Rails application I worked on was a comprehensive system designed for an insurance company. Its core functionalities included storing customer information, sending emails through the platform, and managing payments made to customers.- Implemented background jobs using Sidekiq to handle asynchronous tasks such as sending payment notifications and bulk email campaigns.- Leveraged Docusign API to create dynamic and customizable email templates tailored to different customer interactions.- Refactored older parts of the codebase to ensure adherence to DRY principles and improved readability.- Refactored all the system frontend to a more appealing interface.- Conducted database optimizations to ensure the application could handle growing datasets without performance degradation.- Ensured robust test coverage with RSpec and FactoryBot to catch bugs early and maintain system reliability.The second project was a FastAPI backend paired with a React frontend to build a medical consultation system. This application stored patient data, tracked illnesses, and maintained consultation histories.-Designed RESTful APIs with FastAPI to efficiently handle patient data while ensuring compliance with data protection regulations.-Utilized Python's asynchronous capabilities to enhance API performance, especially under high request loads.-Implemented OAuth2-based authentication to secure sensitive medical data.-Built a user-friendly interface in React, leveraging Material-UI for consistent and accessible design.These experiences have solidified my ability to navigate diverse tech stacks and deliver reliable, secure, and performant applications tailored to client needs.

Partner and project manager of technology and security solutions. Iworked in the management of security and intelligence projects incondominiums and companies, today I only work as a partner.

End-to-end application development using Django, ReactJS, Docker, and relational databases such as PostgreSQL and MySQL, in projects that spanned from conception to the delivery of complete solutions.One of the projects was a web application developed with Django and ReactJS, designed to manage the registration and operation of an e-commerce platform. This application enabled product management, inventory control, order processing, and integration with payment systems.- Modeled the database with PostgreSQL, optimizing queries to ensure system scalability as the data volume increased.- Developed RESTful APIs with Django to support features such as product registration and querying, payment integration, and sales reporting.- Implemented authentication and authorization using Django Rest Framework (DRF), ensuring security for different user profiles, such as administrators and sellers.- Built a dynamic and responsive interface with ReactJS on the frontend, focusing on delivering a smooth user experience.- Set up the development and production environments with Docker, ensuring the application was easily replicable and portable.- Performed unit testing on the backend using Pytest, ensuring high reliability.These projects solidified my experience working with modern and diverse stacks while enhancing my ability to deliver scalable and secure solutions tailored to client needs.
