About this gig

Planning a SaaS product? I build multi-tenant platforms that are ready for paying customers, not demos that break at the first sign-up.


What you get:

  • Multi-tenant architecture: tenant isolation, roles, permissions and per-tenant settings
  • Auth, team invites, subscription billing (Stripe or Razorpay) and plan limits
  • Admin back office to manage tenants, plans and support
  • Documented REST APIs
  • Docker deployment on AWS, Google Cloud or your VPS


Tech stack:

Next.js/React front end; NestJS, Go (Fiber) or Laravel back end; PostgreSQL or MySQL, Redis, and Kafka when you need event-driven scale.


Recent builds:

  • Commerce SaaS: Next.js storefront on a NestJS API
  • Training and assessment SaaS with Python processing services
  • Workflow-automation SaaS with its own API
  • Community platform on Go + Kafka for high-volume feeds


How I work:

Architecture follows the problem, not trends. You get weekly demos, a staging link, and clean code a future team can pick up.


Send me your idea and I'll reply with a scoped MVP plan and timeline.
