Hello
Building things people depend on
I'm Lawal Oyinlola, a Frontend Engineer building fast, accessible web products across FinTech, GPS/IoT, and AI — mostly in React, Next.js, and TypeScript.
Over 3+ years I've led small teams and shipped real products. I owned the frontend for Trakkam, a multi-tenant GPS fleet SaaS, and took it full-stack on a $5/month VPS — roughly 8× cheaper than managed. On SafulPay, I re-platformed to Next.js and raised Lighthouse from 68 to a perfect 100.
Frontend-first, but I extend into backend, real-time, and self-hosted infrastructure (NestJS, Prisma, WebSockets, NGINX, Docker) when a product needs to ship end to end.
Let's build something people can depend on.

Incubated as an internal product at Tech'N Goodwill, then spun off as an independent fintech company in 2025.
- Re-platformed the SafulPay corporate website to Next.js, raising Lighthouse scores from 68 to a perfect 100 across Performance, Accessibility, Best Practices, and SEO, while also shipping more sections and content, through code-splitting, lazy loading, image optimization, and accessibility hardening.
- Converted complex Figma designs into pixel-perfect, WCAG-accessible components for customer portals and agency monitoring dashboards.
- Engineered the SafulPay v2 frontend architecture with Golang backend engineers on API consumption and complex state management, after co-developing the v1 stack that paired a FlutterFlow frontend with a PHP backend.
- Built the SafulPay Agent & Merchant Onboarding web app used by field marketers, with analytics dashboards, activity monitoring, and a performance leaderboard for tracking marketer productivity.
