Portfolio website design
I designed and built my own portfolio in Next.js, React, and Tailwind so the site itself shows how I work, not just the case studies inside it.
It is an interactive site with case studies, about, and blog. Visitors can move through shipped product work, including PetCard, where I helped ship a real product using AI as a design collaborator. The goal was a clean, conversion-minded site that feels simple and makes the work easy to understand.

I rebuilt the NFCtree website to match the new app.
Same colors, same fonts, same textures, from one design system.
⠀
I explored layouts in Paper first.
Looked at how Anchor, ugly.cash (http://ugly.cash) and Klarna handle scrolling.
Picked one.
⠀
Then I designed it in Figma.
Claude Code turned it into code.
Pushed to GitHub.
Vercel published it.
⠀
The scroll motion is CSS only.
It turns off when reduced motion is on.

Does your website look like your product?

After exploring a range of sci-fi interface concepts, I shifted toward a neomorphic approach to bring in more tactility and depth. The goal was to make the EV display feel less abstract, something more intuitive, approachable, and human to interact with.
This evolved into my most in-depth Rive project to date. With more time, I would have expanded it further by adding additional modes and translating the experience into a fully realized 3D scene. The quality of work others submitted was incredibly inspiring and pushed me to think bigger about what’s possible. As a solo designer, I’d love to collaborate with other Rive artists in the future and build on ideas like this together.

🚨 Your database query works… but it’s taking 3 seconds?
Before rewriting the whole backend, check your database indexes.
One missing index can turn a fast query into a slow one as your data grows.
Optimize the query before optimizing everything else. ⚡
Have you checked your database indexes recently? 👇

Found a bug that only happened in production.
The code looked fine locally. The real problem? A missing environment variable.
Lesson: Always check your production environment variables before rewriting working code. 😅
Have you ever spent hours debugging something that turned out to be a simple configuration issue?

🚨 A bug that looks like a frontend problem might actually be your backend.
I once spent time checking UI code, only to find the real issue was an API returning the wrong data.
When debugging, I always check the full data flow:
Frontend → API → Backend → Database
Debug the source, not just the symptom. 🔍
Have you ever found a backend bug while fixing a frontend issue?
