About Jhon Fernando

Semi Senior Fullstack Developer & Team Lead
With 9 years of experience in software development, I have specialized in building robust and scalable ecosystems, with a predominant focus on Backend Architecture. My technical experience is complemented by technical leadership skills and direct client management, ensuring that business requirements are translated into efficient technological solutions.
Main Technological Stack
Backend: Specialist in Node.js (NestJS with TypeORM, Express with Sequelize) and PHP (Laravel, E-commerce development with Bagisto and WordPress/WooCommerce ecosystems).
Frontend & Mobile: Experience in developing dynamic interfaces using Angular, Vue.js, and React, as well as mobile applications with React Native.

I wish to start a new challenge and position myself in a large company. In my years of experience working for companies in the logistics, accounting, invoicing, e-commerce, education sectors, etc., I have realized that I have developed leadership and critical analysis skills on how things work. Learning is the reason why I believe this company can contribute a lot to me professionally. I just want an opportunity to demonstrate my performance and thus be able to grow professionally.
