My freelancing journey began after gaining experience in marketing for a mid-sized company, where I explored diverse domains like real estate and quality management frameworks such as 5S and Six Sigma. This foundation inspired me to start my own venture, where I initially focused on web design projects.

As a self-learner, I relied heavily on resources like Stack Overflow, YouTube tutorials, W3Schools, TutorialsPoint, and other online platforms to expand my knowledge and develop my skills. Over time, I transitioned into customizing platforms like OpenCart, PrestaShop, and WordPress, delivering tailored solutions for diverse client needs. I also ventured into backend development using frameworks like CodeIgniter, PHP, and Laravel, while enhancing my front-end expertise in Angular, jQuery, HTML, CSS, and JavaScript to create dynamic, user-friendly interfaces.

In addition, I implemented payment gateway integrations for e-commerce projects and, recognizing the growing demand for mobile apps, taught myself Ionic to develop several mobile applications. These self-taught skills enabled me to diversify my portfolio and provide end-to-end solutions to clients.

Throughout my freelancing career, I managed projects independently, from coding and problem-solving to client negotiations, always aiming to deliver high-quality products. However, during the pandemic, an overwhelming influx of projects left little time for my family and personal well-being. This experience led me to transition back to a structured job environment, seeking a better balance between professional and personal life.

My freelancing journey was a testament to self-learning and perseverance, where I continuously evolved by embracing challenges, mastering new technologies, and delivering impactful solutions.
