Starting my career in marketing and graphic design taught me how to think beyond aesthetics — to create digital experiences that communicate, convert, and grow with a brand. That foundation naturally led me into the world of Webflow Development, where I discovered the perfect balance between creativity and control.

Since then, I’ve built websites that not only look great but actually work — for founders, creatives, and teams who see their website as a growth tool, not just a design piece. In 2021, I also started sharing my knowledge through online tutorials and mentoring students.

I learned a lot about web design and web development under the guidance of Mr. Derek. Derek is a great teacher and I thank him for sharing his idea with me and the class.

I did a web development and web design program and it was one of the best. Derek is a very humble person who loves teaching others and providing value. Going to miss going there every Monday.

I learned web design and development under Derek. I am now able to design website from the beginning that looks GOOD. Derek is definitely one of the best coding and design teachers that I've worked with.

In my professional journey, I've had the pleasure of collaborating with Derek, an extremely gifted designer, twice now. Each time, he's consistently gone above and beyond my expectations. If you're seeking a unique, standout website, Derek's expertise would undoubtedly prove invaluable.

Derek is never short on ideas and creativity. Derek was great at analysing our audience, our objectives and coming up with solutions based ideas. He is committed to doing the right thing for the customer and strives to continually improve his skills.

Derek's ambition and passion for his work is evident in every project he works on. Derek is a very talented designer in which his work speaks for itself. I definitely recommend Derek to anyone looking to take their brand to the next level.

Derek is literally the best, he has worked on my website and helped me tremendously!!! Had helped me make 7 figures with just one amazing website. I highly recommend getting your website done by Derek.

Derek has exceptional Webflow expertise and a talent for breaking down technical development into clear, simple terms. His passion for sharing knowledge with the Webflow community is truly inspiring!

I'm so far beyond happy with his service and the final result. Derek's communication is clear and patient, and the work speaks for itself. I'm now the proud owner of a fantastic website. If you want a clear vision, great communication and an awesome final product, I cannot recommend Derek highly enough. Derek is the man! Thank you mate.

Derek knows his craft, he will do the job right. It was a pleasure working with someone who really feels passion for what he does. I can tell he has a lot of experience which makes him work fast if needed and develop a high quality website. He went above and beyond. I will be working with Derek again in the future for sure.

Working with Derek is an absolute dream. He is extremely knowledgeable, but able to break his work and process down in a way that is understandable. He's very thorough with planning, details and gaining a true understanding of the work to be performed before executing flawlessly. I'm all the way in Canada, and am still able to hire Derek as my main web designer and editor! Thank again you Derek!

Highly professional experience for use working with Derek. Easy to work with, clear communications and took notes when we spoke which communicated to us that out website would likely be tailored to us, rather than a generic website.
