About this gig
Building a SaaS isn't just about writing code it's about building a system that handles users, billing, permissions, and scale from day one.

Role-based access control (admin / member / viewer)
Email notifications (welcome, billing, alerts) via SendGrid / Resend

FAQ
I'm a non-technical founder. Can you still help me?
Absolutely, most of my SaaS clients are non-technical. You don't need to know how to code. You just need a clear idea of what your product should do and who it's for. I'll handle the architecture, tech decisions, and implementation. We'll communicate in plain language throughout, and I'll walk you
What exactly is included in a SaaS build, what do I own at the end?
You own everything. At delivery you receive: full source code pushed to your GitHub repository, environment configuration files, database schema documentation, deployment instructions, and a handover call or video walkthrough. No licensing fees, no lock-in. The code is yours to host, modify,
Can you integrate Stripe for subscription billing?
Yes, Stripe integration is a core part of every Standard and Premium SaaS package. This covers subscription plans, free trials, upgrade/downgrade flows, failed payment handling, and webhook processing. I can also set up usage-based billing and one-time payments if your model requires it.
What is multi-tenancy and do I need it?
Multi-tenancy means each customer (tenant) using your SaaS has their data completely isolated from other customers, even though they share the same application. If you're building a B2B SaaS where businesses sign up and manage their own team of users you need multi-tenancy.
How do you handle security for a SaaS product?
Security is built in from the start, not added later. Every SaaS I build includes: bcrypt password hashing, JWT with refresh token rotation, HTTPS-only API, rate limiting on all endpoints, input validation and sanitization, SQL/NoSQL injection prevention, CORS configuration.
Can you build on top of an existing codebase or partially completed project?
Yes, but I'll need to review the existing code first. Share the repository and I'll assess the architecture, code quality, and what it would take to continue. If the existing code is clean and well-structured, continuing is usually faster and cheaper.
Do you offer post-launch support and maintenance?
Yes. I offer a monthly maintenance retainer that covers bug fixes, dependency updates, minor feature additions, uptime monitoring, and priority response. Rates start at $150/month. This is optional, the delivered code runs independently.
What tech stack will you use and can I request something specific?
My default stack is React/Next.js frontend, Node.js/Express backend, MongoDB or PostgreSQL database, and deployment on AWS, Railway, or Vercel. If you have an existing infrastructure preference (e.g. you're already on Azure, or your team knows Python).
