Since 2016, I have been working as an IT consultant at Proximity Indian Ocean, where I am involved in the design, development, and maintenance of web applications. My goal is to leverage my technical and analytical skills in an analyst and developer role.

I first worked as a front-end developer for six months, using Pug, React/Node.js, JavaScript, SCSS, Gulp, and HTML5. This experience allowed me to design dynamic, ergonomic, and high-performance interfaces, while strengthening my skills in code integration and optimization.

I then moved into a back-end developer role, where I gained over two years of experience with C#, ASP.NET MVC 5, Web API, SQL Server, Entity Framework, and the Slim 3 framework. I apply SOLID principles daily to ensure code quality and maintainability.

My role involves analyzing needs, designing, developing, testing, and maintaining several web applications. I collaborate closely with business teams to propose reliable and adapted solutions, while ensuring the performance, security, and quality of the delivered product.

I participated in the design and development of innovative solutions based on the Internet of Things (IoT), aiming to connect different devices and exploit the collected data to improve efficiency and user experience.

My role involved defining the technical architecture, developing application modules, and ensuring communication between connected objects, gateways, and servers. I worked on integrating sensors and smart equipment capable of transmitting information in real-time, particularly via protocols such as MQTT, HTTP, or WebSocket.

On the back-end side, I contributed to the implementation of REST APIs and web services for centralizing, processing, and analyzing the collected data. The environments used included Python and Java, ensuring a scalable and secure infrastructure.

This experience allowed me to strengthen my skills in full-stack development, system integration, and real-time data analysis. It also made me aware of the security, performance, and reliability challenges specific to IoT ecosystems, where every technical decision directly impacts service quality and user satisfaction.
