Guilherme Maróstica

Passionate about crafting and maintaining high-performing websites that blend design and functionality seamlessly. I specialize in HTML, CSS, and JavaScript for sleek, responsive interfaces, and bring strong WordPress and PHP expertise to ensure solid, scalable back-end performance.

Over the past projects, I’ve tackled challenges like optimizing site speed by up to 40%, fixing complex plugin conflicts, and migrating outdated systems to modern, responsive architectures — always with a focus on delivering clean code, strong UX, and measurable business results.

I take pride in turning creative concepts into functional, visually compelling digital experiences that not only look great but perform flawlessly. Whether it’s building from scratch or improving existing systems, I’m here to make ideas come alive online — fast, reliable, and beautifully executed.

As a Web Developer, I played a key role in building and maintaining high-quality websites, using a versatile tech stack that included HTML, CSS, JavaScript, PHP, and WordPress.

I was responsible for developing responsive and engaging front-end interfaces with HTML and CSS, while implementing dynamic, user-focused features through JavaScript. On the back end, my solid understanding of PHP allowed me to design and maintain secure, efficient, and scalable systems that ensured flawless functionality.

I also handled WordPress administration and customization, creating tailored solutions to meet each client’s unique requirements — from plugin optimization to full website redesigns.

Throughout these projects, I consistently overcame challenges such as improving loading performance, resolving cross-browser compatibility issues, and streamlining content management workflows. The result: websites that not only looked great, but also delivered measurable business value and enhanced user engagement.

Whether working independently or as part of a team, I focused on quality, reliability, and attention to detail, always aiming to elevate the online presence of every brand I collaborated with.
