Hi, I’m Cavendish Marvin Pierre-Louis, a Web Architect & Engineer with over 10 years of experience. My work is quiet but precise; shaped by structure, clarity, intention and elegance.
Every project reflects subtle luxury, honest storytelling, and discipline in every detail. From typography and spacing, to color palette and icons, I ensure everything aligns with your brand and goes beyond basic templates to create something authentically yours.
I’m new to Fiverr, not new to the craft. If you want a site that looks good and works, I’m your guy.
Best,

FAQ
What exactly do you fix?
I fix any HTML, CSS, or front-end structural issue; broken layouts, spacing problems, alignment, code errors, SEO gaps, accessibility issues, performance drag, and anything affecting clean front-end presentation.
Do you touch JavaScript too?
Yes. I correct small JS issues, improve interactions, clean unused scripts, and optimize load behavior. (If a project requires a major JS rebuild, I’ll quote separately.)
Will my code be W3C Valid after your work?
Yes, every package includes validation. STANDARD and PREMIUM include full error resolution.
Can you optimize my website for SEO?
Absolutely. I improve: • Titles & meta descriptions • H-tag hierarchy • Image alt tags • Link structure • Mobile responsiveness • Performance recommendations • Core layout for better indexing PREMIUM includes schema markup and deep SEO structuring.
Do you redesign the website visually?
If needed, yes. This gig focuses on HTML/CSS/JS fixes, cleanup, and performance/SEO improvements. Standard and Premium may include small structural corrections, but full visual redesigns are offered only through my HTML Website Design service.
What if my site is very messy?
I specialize in cleaning poorly structured HTML. If the site is huge, I’ll advise the best approach, but no project is “too broken.”
Do you work with Wix, Shopify, or WordPress?
Yes. My main expertise is HTML/CSS/JS, along with complete Wix site development. I’m also capable of handling Shopify front-end work, including custom code blocks, theme edits, and structural fixes. If your project requires custom code inside one of these platforms, I can handle that too.
Will you keep my design style?
100%. I fix the code without changing your identity, spacing, branding, or visuals.
Will I be able to see exactly what you changed?
Yes, I can provide a changelog or GitHub commit summary if requested.
