About me
I am an experienced frontend developer specializing in JavaScript. I am passionate about creating robust web, mobile, and desktop applications using modern technologies. I have focused primarily on exploring new technologies, striving every day to create increasingly efficient and comprehensive solutions. I enjoy working in a team, fostering the skills of all members to form a team based on constant improvement, communication, and trust. I believe that in this field, everything has a solution and that nothing is impossible for a developer, as the only limit is oneself. One of my motivations is to make the decision every day to give my best to achieve success. I am always open to change and willing to learn whatever is necessary to achieve the objectives. I adhere to best practices in every stage of development, including clean architecture, SOLID principles, pixel-perfect design, GitFlow, and agile methodologies.

Practices
My work process
Meeting
The first step is to hold a meeting to learn about your expectations, objectives and project requirements. It is important to discuss the scope of the project, the resources required and the project delivery schedule.
Prototyping
With the action plan already defined, the web designs are made. Through Figma, mockups will be presented so that you have an image of what will be your website with the chosen colors and fonts, adapted for all devices and prioritizing usability.
SEO and content
The next step is to implement an SEO and content strategy to help improve a website´s visibility in search engine results, which can generate more traffic and improve the quality of visitors.In addition, a well- structured content strategy can also contribute to better and longer - lasting results.
Development phase
Once the design has been approved, the layout will be designed in the test environment and all the functionalities will be implemented so that the website takes shape. In the case that a website with SEO and content has been contracted, they will also be applied in this phase.
Test phase
You want a beautiful website, but you also want it to work perfectly, so in this phase we do all kinds of tests to make sure it´s fast, accessible, intuitive, secure, with a good responsive design, etc.
Migration
You are done. Congratulations, you have a website created by me. You will also have the option to hire my web maintenance service, so that it is always updated and ready.
