I’m a Full-Stack Engineer and Creative Director with 3 years of experience shipping fintech products—wallet systems, payment integrations, and transaction dashboards—that real users trust with their money. I build integrations that drive measurable business outcomes, not just features.

At PayVault Technologies, I led end-to-end engineering of a fintech wallet platform using React + Tailwind CSS on the frontend and Node.js + Express with PostgreSQL on the backend, including Flutterwave API integration for payment processing and virtual account provisioning. I implemented webhook-based transaction status relay to deliver live payment feedback in under 2 seconds, and built a 3-tier role-based admin panel (Super Admin, Manager, Agent) with live monitoring, KYC review workflow, flagging queue, and CSV export—reducing support tickets by 40% and cutting onboarding from 48 hours to under 2 minutes.

Design is part of how I ship. I establish design systems with shared component libraries and design tokens to maintain consistency as products scale, and I connect UX decisions directly to the engineering that powers the flow. The way I work is “integration”—the engineer who builds your payment flow is the same person who designed the UX around it and created the ad that drove users to it.

Before and alongside engineering, I’ve delivered brand and performance creative for fintech teams: I created brand identity systems for 3 fintech startups and produced 12+ ad creative variants for Meta and Google with improved CTR versus previous creatives. As a Video Ad Creator & Motion Designer at Nova Digital Agency, I produced 8 brand and product videos across 5 fintech clients, achieving 3.1× higher view-through rate versus static alternatives while keeping a compliance-first workflow (zero compliance rework on any project).
