What We Build

Custom Web Application Capabilities

From a simple internal tool to a multi-tenant SaaS platform — we cover the full spectrum of web application development.

SaaS Platforms

Multi-tenant web applications with subscription billing, role-based access, and the scalable architecture to grow from 10 to 10,000 users.

  • Multi-tenancy & team management
  • Subscription & billing integration
  • Usage analytics & admin dashboards

Business & Customer Portals

Secure, login-gated portals for clients, vendors, or staff — with real-time data, document management, and workflow automation.

  • Role-based access control (RBAC)
  • Real-time notifications & alerts
  • Document upload & e-signature

Dashboards & Data Visualisation

Interactive analytics dashboards that connect to your data sources and give stakeholders the live visibility they need.

  • Real-time charts & KPI tracking
  • CSV & PDF report exports
  • Third-party data integrations

REST API & Third-Party Integrations

Custom APIs, webhooks, and integrations with payment gateways, CRMs, ERPs, and external services — reliably documented and tested.

  • RESTful & GraphQL API design
  • OAuth 2.0 & webhook support
  • CRM, ERP & payment integrations

Workflow & Process Automation

Replace repetitive manual processes with automated workflows — approvals, notifications, report generation, and scheduled tasks.

  • Multi-step approval workflows
  • Scheduled jobs & queue workers
  • Email, SMS & in-app notifications

Legacy System Modernisation

We rebuild outdated desktop software, spreadsheet workflows, and aging codebases into modern, maintainable web applications.

  • Phased migration with no downtime
  • Data migration & integrity checks
  • Staff training & handover

Built to Last

Web apps that perform under pressure

A web application is only as good as its architecture. Every app we build is designed for performance, security, and long-term maintainability — not just the first release.

  • Secure by design

    OWASP Top 10 protections, CSRF, XSS, SQL injection prevention, and regular dependency audits baked into our development process.

  • Fast page loads

    Server-side rendering, query optimisation, caching layers, CDN delivery, and Lighthouse CI monitoring keep your app responsive for all users.

  • Maintainable codebase

    Clean architecture, documented APIs, automated test suites, and consistent code style mean your team can own and extend the product confidently.

  • Production-ready deployments

    CI/CD pipelines, environment-specific configs, zero-downtime releases, and rollback procedures so your launch is smooth and stress-free.

Our Process

How We Deliver Web Applications

A structured, collaborative process focused on early validation, clean code, and a smooth launch.

  1. Step 01

    Discovery & Scoping

    We define user personas, map user journeys, agree on platform targets, and produce a detailed feature list and scope document.

  2. Step 02

    UI/UX Design

    Wireframes, clickable Figma prototypes, and a finalised design system — reviewed with you before development starts.

  3. Step 03

    Development & QA

    Agile sprints with fortnightly demo builds. Automated tests, manual device testing, and crash reporting run throughout.

  4. Step 04

    Store Launch & Support

    We handle store submission, review communication, and post-launch monitoring — then stay on hand for updates and fixes.

Our Difference

Why Vaidikalaya for Your Web Application

We are a focused team that builds products we stand behind. Here is what that means for your project.

Architecture

Clean architecture from day one

We follow SOLID principles, domain-driven design where appropriate, and write code structured for maintainability — not just the first feature release.

  • Service layer & action pattern
  • Feature-driven folder structure
  • API versioning built in
Our engineering standards
Transparency

Fortnightly demos, no surprises

We work in two-week sprints with a live demo at the end of each cycle. You see progress early, give feedback quickly, and avoid costly late-stage changes.

  • Sprint planning & backlog grooming
  • Demo calls every two weeks
  • Shared project board (Jira / Linear)
Our project process
Ownership

You own everything — always

All source code, assets, and infrastructure belong to you from day one. We hand over full access at every milestone, not just at the end.

  • Git repository transferred on day 1
  • Full documentation & README
  • No vendor lock-in
Our handover process
Choosing the Right Approach

SPA vs SSR vs Traditional

We recommend the right rendering approach for your use case. Here is a plain-English guide.

Factor SPA React / Vue SSR / Inertia Laravel + Inertia Traditional Blade / MVC
Initial Load Slower (JS bundle) Fast Fastest
SEO Needs extra config Excellent Excellent
Interactivity Richest Rich Good
Complexity Higher Moderate Lower
Best For Dashboards & apps Content + apps Content-first sites

FAQs

Common Questions

Straightforward answers to what clients usually ask before starting a web application project.

A website primarily presents information — it is mostly read-only. A web application has user authentication, data input, business logic, and dynamic content. Examples include admin panels, booking systems, project management tools, and customer portals.
A focused internal tool or MVP can take 6–10 weeks. A full SaaS platform with subscriptions, onboarding, and integrations is typically 4–6 months. We provide a detailed milestone plan after the discovery phase.
We are a full-stack team. We design and build the database schema, server-side application, REST API, and frontend UI — or we can work with an existing backend or frontend if you already have one in place.
Yes. We regularly integrate web applications with CRMs (Zoho, Salesforce), payment gateways (Razorpay, Stripe), ERP systems, accounting software, and communication tools (Slack, email). We audit the available APIs during discovery.
You own everything. The source code is transferred to your Git repository, and hosting is set up under your own cloud account. We do not hold any leverage over your infrastructure.
We offer a structured maintenance plan covering bug fixes, security patches, dependency updates, and feature development. We can also help you build an internal team to take over ownership gradually.
