I build HIPAA-compliant React and Next.js healthcare and SaaS interfaces.

Nigeria
Message

At WithinLabs, I build HIPAA-compliant healthcare dashboards and Next.js marketing sites, integrating 30+ REST API service modules across billing, insurance, subscriptions, promotions, waitlists, templates, and user management.

I've implemented Stripe subscription migrations, insurance analytics and reporting workflows, parameterized query builders, and token-authenticated API calls with refresh queue coalescing. My work improved interface responsiveness by 40% while maintaining zero PHI exposure in real-time analytics dashboards.

I also maintain CI/CD pipelines that deploy to Cloudflare Workers via OpenNext, and write unit and end-to-end tests with Vitest, Testing Library, and Playwright.

Previously, I improved engagement for an auction marketplace at Intern Pulse and increased e-commerce page-load speed at Afribreath Ltd through responsive components, API integrations, Tailwind CSS, TypeScript, and Git-based workflows.
