Uilliam S.

Full Stack Developer

Freelancer based in Dubai, United Arab Emirates.

I am a multidisciplinary professional with a unique combination of technology expertise and investment consulting experience, passionate about building digital solutions and guiding clients through strategic decisions in Dubai’s dynamic real estate market. With a degree in Systems Analysis and Development (FATEC – São Paulo, Brazil) and years of hands-on work as a Front-End Developer and Software Engineer, I have built web applications and digital platforms using HTML, CSS, JavaScript, React, Angular, Java, SQL, and WordPress. My technical career began at CI&T, where I collaborated on large-scale projects, refactored legacy code, optimized user experience, and trained cross-functional teams. At Arpejo Publicity Agency, I combined creativity with technical execution, developing responsive websites, managing databases, and supporting network infrastructure. These experiences shaped me into a developer who is detail-oriented, adaptable, and committed to delivering intuitive, high-impact solutions. Beyond IT and real estate, I have a diverse international background in hospitality and customer operations, as well as experience as a professional poker player. These roles sharpened my resilience, decision-making under pressure, and ability to build trust with people from different cultures — qualities that I carry into every professional environment.
