So, Who Am I?
馃殌 Software Developer | 馃挕 Entrepreneur | 馃寣 Tech Explorer
Hey I'm Jeisson, Full Stack Developer with a passion for creating innovative digital experiences. My interest in technology started when I was young, when I changed a text on a web page using the element inspector as a joke for my teacher. Since then, I haven't stopped exploring and learning about web development and emerging technologies.
Today, I focus on creating accessible and efficient solutions to improve people's lives, working with companies of various sizes and leading innovative projects.

ProjectsHow I Work on Developing My Projects
My development process follows an iterative cycle that ensures quality and efficiency. It starts with requirements analysis, followed by design and development, where it is ensured that the project is aligned with the client's needs.
In each phase, continuous testing is performed to detect and correct errors, ensuring that the product functions optimally before deployment.
Finally, after deployment, the process is repeated, allowing for constant improvements and adaptation to new requirements.
