I will develop a custom web application and saas platform
Maneesha G
About this gig
Your web app should still work when your business grows.
I build custom web applications and SaaS platforms that hold up in production - not just in a demo.
WHAT I BUILD
- SaaS platforms and multi-tenant systems
- Admin dashboards and internal business tools
- Custom web apps: CRM, inventory, booking, POS
- REST APIs and third-party integrations
- Authentication, roles, permissions and payments
MY STACK
React, Next.js, TypeScript, Tailwind, Node.js, Java, Spring Boot, PostgreSQL, Docker, AWS
WHAT YOU GET EVERY TIME
- Clean, documented code that you fully own
- Tested and deployed, not just handed over
- Daily progress updates, so you are never left guessing
- A walkthrough video showing exactly how it works
I have built a multi-tenant fintech platform with 15 modules including compliance, audit logging and role-based access, plus polished client-facing web apps. Same engineering standard either way.
MESSAGE ME BEFORE ORDERING with what you are building. I will reply with an honest scope, timeline and price, usually within the hour.
Let's build something that lasts.

My Portfolio
FAQ
Do I own the code and everything you build?
Yes, 100%. You receive the full source code, repository and documentation. No lock-in, no licensing, and no dependency on me afterwards.
Can you work with my existing app or codebase?
Yes. I audit it first and tell you honestly whether to build on it or rebuild - including when rebuilding would be the wrong call.
Which package do I need?
Message me first and I will tell you straight. Basic suits a small tool or MVP. Standard covers most business apps. Premium is for full platforms with payments.
My project does not fit these packages. What now?
Most projects do not fit exactly, and that is normal. Send me your requirements and I will create a custom offer with exact scope, price and timeline.
Do you handle both frontend and backend?
Yes. Frontend in React or Next.js, backend in Node.js or Java Spring Boot, plus database design, deployment and CI/CD. One person, no handoffs.
What happens after delivery?
You get a walkthrough video and documentation, and I stay available for questions. I also offer a monthly maintenance option if you want ongoing support.
