POC Sports wanted to rebuild their e-commerce platform from the ground up. Their existing Shopify-based site was slow, limited, and not scalable for their global needs. The new site needed to:

- Load faster for users worldwide ⁠- Reflect a refreshed design ⁠- Be built on Centra, a powerful e-commerce engine ⁠- Launch before their old payment system expired

This was a high-priority project with a sharp deadline and international scope — the site had to work across 24 markets.

👨‍💻 My Role

I was the Lead Frontend Developer, responsible for the entire frontend architecture and implementation. We used Next.js App Router, which meant working with both client and server components — a fullstack-like setup.

I collaborated daily with: ⁠ ⁠The designer, to implement a pixel-perfect, responsive UI ⁠The backend developer, to handle data from Centra and Sanity ⁠The architect and project lead, to align on delivery goals and performance

🛠️ What I Built

Together with the team, I built the full site:

Product pages, category listings, cart & checkout ⁠CMS-driven pages powered by Sanity ⁠E-commerce integration with Centra (product data, inventory, etc.) ⁠Payment integration with Adyen ⁠Marketing tools like Klaviyo and Gladly

I also focused on performance, accessibility, and global scalability.

⚠️ Challenges We Faced ⁠⁠⁠Tight deadline: We had to deliver before the old payment system expired. This shaped how we prioritized features and bugs. ⁠Performance issues: I learned that Vercel won’t cache pages larger than 2MB, which required code and data optimizations. ⁠Product complexity: POC’s product structure had special rules for sizes, variants, and availability that needed careful handling in the UI.

✅ The Result ⁠

A modern, fully custom e-commerce website

Live in 24 international markets

Faster load times and smoother UX

Improved accessibility and responsive design

Future-proofed on scalable tools like Centra and Sanity

📚 What I Learned

• Deepened my experience with Next.js App Router in a real-world project
• ⁠⁠Learned how to manage caching, data handling, and performance on Vercel⁠
• Gained experience building an e-commerce system that scales globally
