About

I’m Quan Vĩ Hồng (Dennis), a frontend developer with 4 years of experience building scalable, high-performance business applications using React and Vue, along with modern styling approaches like Tailwind CSS, SASS, and design-system thinking. I enjoy turning Figma and product requirements into clean, maintainable and accessible UI.

In my recent roles, I’ve worked across multiple projects in product ecosystems (including Corsair’s iCUE-related web products), collaborated with QA across time zones, triaged and resolved bugs, and helped standardize component and typography practices for reusable brand-specific UI. I used to work freelance providing AI automation and bespoke web applications, partnering with clients to streamline repetitive workflows —always with a focus on practical UX improvements, performance, and reliable delivery. Along with client projects I’ve also built a payment gateway and a landing page with the help of fellow freelancers.

With the knowledge I’ve accrued over the years, I’m pivoting to creative development—crafting beautiful marketing, e-commerce, and portfolio sites for agencies, startups, and brands looking to sell in style.

The page was custom built over 2 to 3 weeks and was first deployed on Vercel in 2020, more than one year before GPT-3 was released. Therefore 90% of the site is coded by hand.

Built with just React, Javascript and Sanity CMS, the site has everything you need to know about me, from work history, to pet projects I coded during the college years, to trinket blog posts hosted through Sanity.

Despite the minimalistic design, the site fares well in performance and responsiveness, the site goes well with Google Core Web Vitals and you can view this site with just about any device in any network conditions.

Creative Developer Portfolio

I've been passionate about writing stories outside of work, and I discovered that the world of frontend development would be helpful in turning stories and narratives into immersive storytelling experiences on the web. Storytelling website development is for ideas that can't be expressed through a conventional page. Instead of simply presenting information, the website turns the narrative itself into an interactive experience—using scroll-driven storytelling, horizontal journeys, animated transitions, and responsive visuals to guide visitors through the story. The goal is simple: motion carries meaning. Every interaction, transition, and visual element contributes to the narrative, creating a website that feels less like a collection of pages and more like a story unfolding in front of you. The site is my take on storytelling web development and with the power of Three.js, GSAP and React, anyone having these sites in their portfolio kit will see an enhancement in their brand image and an uptick in outreach potential.
