With a keen passion for web development and a relentless drive for customer satisfaction, I offer expertise steeped in real-world experience. I strive to build long-lasting partnerships with my clients, grounded in mutual respect, transparency, and shared success. I specialize in creating dynamic e-commerce websites using WordPress, utilizing advanced tools such as Oxygen and Bricks for larger, scalable projects, and Breakdance for smaller, quick-turnaround tasks. Though I have experience with Divi, I have transitioned to these more sophisticated tools to offer my clients cutting-edge solutions that promote growth and versatility. But my proficiency doesn't end at front-end development. I'm also well-versed in Linux system administration, which provides me with a deep understanding of the server-side interactions crucial to website speed optimization. I am skilled in building and configuring VPS for your website, and can even provide custom infrastructure solutions for more advanced projects. A common issue I've observed in the industry is the blame placed on hosting companies for server-side problems, when in reality, these issues often stem from poor configuration and website optimization. My expertise allows me to preemptively address these concerns and assure a smoothly running, fast-performing website for your business. Don't hesitate to reach out if you have any questions or if you're ready to begin our partnership. I look forward to bringing your vision to life.
