Custom Website Development for Fintech: Zing.me

As a Senior Frontend Software Developer at Zing.me, I played a key role in building the fintech platform’s core web solutions from the ground up. This wasn’t just about coding—I architected systems that made everything work seamlessly behind the scenes while ensuring the site looked stunning upfront. Think of it as blending rocket science 🚀 with a touch of art 🎨.

Here’s what I worked on:

Custom API Architecture: Designed and implemented Next.js API routes to act as a smart middleman between third-party APIs (like Mixpanel and Viral Loops) and our backend. This ensured seamless data flow and reduced downtime.

Performance Boosting: Took a sluggish Lighthouse score of 73 and turbocharged it to 93, thanks to code refactoring, lazy loading, and asset optimization. Speed is everything when you’re competing in fintech!

Reusable Components: Developed React components with Storybook for easy documentation and reuse. It’s like leaving breadcrumbs for future developers so they don’t get lost.

Security First: Ran SAST scans with Checkmarx, patched vulnerabilities, and implemented OWASP-compliant security measures, including robust authentication and input validation. Cybersecurity is non-negotiable in fintech, and I made sure our system was airtight. 🔒

Uptime Guardian: Built an API health check endpoint to monitor and validate system health 24/7. No surprises, no downtime—just reliability.

Accessibility Hero: Fixed all accessibility violations to make the platform inclusive for all users, regardless of their abilities.

This wasn’t just about tech—it was about crafting an experience. From brainstorming features to debugging tricky production incidents, I poured my heart into creating a platform that balances security, performance, and user delight. 💡

I’m especially proud of how we turned complex technical requirements into a clean, intuitive, and responsive site that meets the high expectations of fintech users. It’s not just a website; it’s a scalable, secure solution that stands out in the fintech world
