About Me

I’m a versatile web developer with a strong educational background and hands-on experience in both front-end and back-end development. Based in Calgary, AB, I specialize in creating dynamic, user-friendly, and responsive websites. I’m proficient in HTML, CSS, and JavaScript, and I use tools like WordPress, DIVI, and Adobe XD to craft seamless and engaging user experiences.

In addition to web development, I bring expertise in SEO best practices, e-commerce solutions, and basic cybersecurity. I also have practical experience in digital marketing, including Google Ads, social media advertising, and online marketing strategies—paired with a strong command of analytics tools to drive performance and optimize campaigns.

I hold a diploma in Web Design and Development and a Bachelor of Science in Information Technology. My professional journey spans freelance work, e-commerce development, and technical supervision. I’m passionate about merging creative thinking with technical expertise to deliver digital solutions that are both innovative and results-driven.
