What We Deliver

Everything Included in This Service

Not every business problem can be solved by an off-the-shelf software subscription. When your requirements outgrow generic tools — or when you want to build a product to sell to others — you need a custom web application built specifically for your workflows.

At NiyajTech, we build production-grade SaaS platforms, internal dashboards, multi-tenant portals, and AI-integrated web applications from the ground up. Our stack — Next.js frontend, Node.js or FastAPI backend, PostgreSQL database, deployed on AWS or Vercel — is chosen for performance, reliability, and long-term maintainability.

We work with early-stage startups building their first product, established businesses replacing legacy internal tools, and companies integrating AI capabilities (OpenAI, Anthropic Claude, Google Gemini) into their existing platforms.

Best for: Startups and scale-ups building SaaS products, admin dashboards, internal tools, or AI-enhanced platforms.

What's Included

  • Multi-tenant SaaS architecture (separate data per customer)
  • Role-based access control (RBAC — admin, manager, user roles)
  • REST or GraphQL API development with full documentation
  • Third-party integrations (Stripe, Razorpay, Twilio, SendGrid, etc.)
  • Cloud deployment (Vercel, AWS, DigitalOcean)
  • AI integrations (OpenAI, Anthropic Claude, Google Gemini)
  • Admin dashboard and analytics panel
  • Automated testing and CI/CD pipeline setup

Why NiyajTech

What Makes Our SaaS & Web Applications Different

01

Full-Stack Ownership

We build and own every layer — frontend, backend, database, and deployment. No coordinating between multiple agencies or freelancers.

02

Multi-Tenant Architecture

Proper SaaS requires data isolation between customers. We build multi-tenant systems from day one — not bolted on later when it becomes a security problem.

03

AI-Ready

We integrate OpenAI, Anthropic Claude, and Gemini APIs into your platform — whether that means an AI chatbot, document analysis, content generation, or intelligent automation.

04

Subscription Billing Built In

Stripe integration with subscription plans, trial periods, usage-based billing, and a customer billing portal — the full monetisation infrastructure for your SaaS.

05

Secure by Design

JWT authentication, encrypted data storage, rate limiting, input sanitisation, and regular dependency audits — security is built into the architecture, not added at the end.

06

CI/CD and Monitoring

Automated deployments, staging environments, error monitoring (Sentry), and uptime alerts — so you can ship with confidence and know instantly when something needs attention.

How It Works

Our SaaS & Web Applications Process

A clear, proven process so you always know what happens next — no surprises.

01

Requirements & Architecture

We document every feature, user role, and data flow. We design the database schema and API architecture before writing code — avoiding expensive structural changes later.

02

Design System

A consistent design system and component library is established first — ensuring the UI scales cleanly as new features are added over time.

03

Core Platform Build

Authentication, user management, RBAC, and billing infrastructure built first. These are the foundations everything else builds on.

04

Feature Development

Features built in two-week sprints with working demos at the end of each sprint. You see progress continuously — not just at the end.

05

Testing & Security Audit

Automated tests for all critical paths. Manual QA for the full user journey. Security review for authentication flows, API endpoints, and data handling.

06

Deployment & Handover

Production deployment with monitoring, logging, and alerting configured. Full technical documentation and codebase handover. Ongoing support available.

FAQs

Common Questions About SaaS & Web Applications

Q. How is a SaaS project priced?

SaaS projects are scoped and priced based on the number of features, complexity of the data model, integrations required, and timeline. We break the work into clearly defined milestones with fixed prices for each — so you always know what you are paying for.

Q. Do you sign NDAs?

Yes, always. We sign a mutual NDA before any detailed discussion of your product concept or business logic. Your idea is protected from the first conversation.

Q. Who owns the code?

You do. On final payment, full ownership of all source code, assets, and documentation transfers to you. We do not retain any licensing rights.

Q. Can you continue building after the initial launch?

Yes — this is common. Many clients engage us on a monthly retainer after the initial build to continue adding features. We can also hand over to your internal team with full documentation.

Q. Do you build with AI integrations?

Yes. We have built platforms integrating OpenAI GPT-4, Anthropic Claude, and Google Gemini for use cases including document analysis, AI chat interfaces, content generation, and intelligent data extraction.
