Oluwafemi Soaga

I’m a versatile frontend engineer with 6+ years designing and scaling modern web applications across fintech, e-commerce, and SaaS. I specialize in React, Next.js, and TypeScript, with strong backend experience spanning NestJS, MongoDB, and PostgreSQL.

I built a payment gateway that processed over 10,000 transactions monthly, improving user retention by 25%. I focus on developer experience, automation, and high-impact product development, aiming for meaningful business outcomes from secure payment gateways to enterprise dashboards.

In my current role as Senior Frontend Engineer at AlertMFB (January 2026–Present), I lead a team of three engineers in delivering projects across the full software development lifecycle—from requirements gathering and UI design to development, testing, and production deployment. I have optimized Core Web Vitals to achieve sub-two-second load times and Lighthouse performance scores above 90 while delivering scalable, high-performing web applications and marketing platforms for fintech and SaaS products. I have also mentored two junior developers, strengthening their coding skills, code quality, and understanding of modern frontend development best practices.

Previously at UniswitchNg (October 2023–Present), I spearheaded Sarepay Checkout, a secure payment gateway processing thousands of monthly transactions, and improved HRDesk performance by 40% to increase user retention by 25%. Earlier work includes building responsive enterprise SPAs with React, Vue, and Angular at Bincom Dev Center (Jan 2021–Dec 2022), and rolling out a reusable UI kit with measurable performance gains at Tech Citadel (Sep 2024–Jan 2025).
