During my role as Lead Architect in a modernization project, I faced the challenge of migrating a monolithic system to the cloud using serverless technologies.My main task was to design a development cycle that would adapt to the needs and tools of each team involved in the project. Additionally, I had to implement appropriate design patterns for each technology used. I was also entrusted with implementing a WebSocket application with compatibility for specific hardware devices, such as thermal printers and scanners. For the backend, I adopted a serverless architecture using AWS services.I led close collaboration with the development teams and designed a flexible development cycle tailored to the needs of each team. I implemented specific design patterns for each technology, such as micro frontends, Hexagonal Architecture, and Atomic Design, to ensure clean and modular code. Additionally, I designed a WebSocket app that worked with specific hardware devices, improving system compatibility and functionality. In the backend, I designed and implemented a serverless architecture based on AWS services to ensure scalability and efficiency.As a result of these actions, we achieved a successful modernization of the monolithic system, migrating it to the cloud with serverless technologies. The customized development cycle and implemented design patterns allowed for efficient collaboration between teams and the creation of high-quality code. The WebSocket application improved interoperability with specific hardware devices, and the serverless architecture in AWS ensured scalability and operational efficiency.

During my tenure as Development Team Leader at Threekit, I was entrusted with the task of incorporating innovative technical solutions for the implementation of augmented reality and 3D models into their e-commerce platforms.My main responsibility was to design various technical solutions that would enable the integration of augmented reality and 3D models in record time.
