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

I've delivered Stripe billing workflows, real-time analytics dashboards, parameterized query builders, secure token refresh handling, and Cloudflare Workers deployments. Previously, I improved marketplace engagement at Intern Pulse and e-commerce performance at Afribreath through responsive components, API integrations, TypeScript, Tailwind CSS, testing, and accessible design.
