Experienced Full-Stack TypeScript Developer (NestJS + Next.js 15 + Prisma/PostgreSQL)

We need an experienced developer to assist our team to build new features on an established multi-tenant healthcare SaaS platform. The top 5 skills required: TypeScript (end-to-end), NestJS (backend API), Next.js 15 (App Router frontend), PostgreSQL with Prisma ORM, and Redis (caching and job queues). The codebase is well-documented with strict conventions — you'll be expected to follow existing patterns, meet HIPAA security and WCAG 2.1 AA accessibility standards, and write tenant-scoped, audited code. Please include links your public repository in your proposal. You will not be considered without one.
