At Tajera Software Solutions, I lead projects from client brief through production delivery across learning platforms, SaaS, e-commerce, and marketplaces. I build React and Next.js applications, backend services, and Flutter apps, and work with clients on workflows and product decisions.

For NAAB, I owned desktop, mobile, and web delivery through Versions 1 and 2, building patient profiles that combine dental charts, records, and treatment history. I also built PinCRM, a multi-tenant real-estate product connecting leads, inventory, offers, approvals, and deal execution.
