Senior Full Stack Web DeveloperBrasília, DF, Brazil – 2014 ~ 2023
As a full-stack PHP developer, applications were developed, configured, and installed, and systems were integrated to provide web solutions for clients. Proficiency in PHP (using Yii or Laravel Frameworks) and JavaScript (including Typescript front-end frameworks) enabled the delivery of robust and scalable web applications.
To ensure codebase quality and reliability, GIT and SVN were utilized for code version control, and unit coding testing (PHPUnit and Sonar) was performed. Additionally, agile, GLPI, and SCRUM methodologies were employed for project management, ensuring efficient and effective delivery of high-quality solutions to clients. Skills in analysis and UX design were applied, with a focus on accessibility and adherence to the W3C and WCAG guidelines. This facilitated the creation of intuitive and user-friendly web applications that met the needs of clients and their customers.
The goals as a full-stack PHP developer were to achieve the following objectives: The company's revenue was aimed to be increased by obtaining a minimum of 30% increase in Total Sales Units (TSU) through successful implementation of web solutions that met clients' needs and exceeded their expectations; Timely delivery of projects was ensured by completing sprints five days ahead of the deadline. This allowed effective management of client expectations and establishment of a reputation as a reliable and trustworthy partner for web development requirements.
By achieving these goals, contributions were made to the growth and success of the company, while also enhancing skills and knowledge as a full-stack developer.
