Custom software · Gurugram, Haryana
Software Development Company in Gurugram
We design and build custom web applications, backend APIs and databases for businesses that have outgrown spreadsheets, disconnected tools or an off-the-shelf product that no longer fits how they work.
WebNest Studio is based in Gurugram and works with businesses across Delhi NCR, the rest of India and remote clients. One team handles the interface, the API, the database and the deployment, so the parts are designed to work together from the first release.
What businesses usually come to us with
Work that lives in spreadsheets and chat threads
Orders, bookings, approvals or client updates are tracked by hand in several places. Data gets typed in twice, status is unclear, and nobody has one reliable view of what is happening.
A website that needs to become an application
A marketing site worked at launch, but customers now need accounts, payments, uploads or a portal. Bolting these onto a template creates fragile code and security gaps.
Systems that do not talk to each other
The payment gateway, email provider, invoicing and internal records each hold part of the truth. Without an integration layer, reconciling them is manual and error-prone.
An existing product that is hard to change
Every new feature breaks something else, deployments are risky, and the original developers are no longer available. The business needs a codebase it can keep building on.
What we build
- Web applications
- React interfaces for customers, staff and administrators, with role-based screens, forms with validation, and layouts that work on phones as well as desktops.
- Backend APIs
- REST APIs in Java with Spring Boot or in Python with FastAPI, structured around your business rules rather than around database tables.
- Databases and data models
- PostgreSQL and MySQL schemas designed for the relationships in your data: customers, orders, payments, documents and audit history.
- Integrations
- Payment gateways such as Razorpay, transactional email, PDF generation, and third-party APIs connected through a backend that verifies results instead of trusting the browser.
- Customer and client portals
- Signed-in areas where your customers can see their orders, project status or documents without having to email you for an update.
- Modernising an existing system
- Reviewing an existing codebase, stabilising what matters, and replacing the riskiest parts in stages instead of an all-at-once rewrite.
How we engineer it
Most problems in custom software come from decisions that are invisible on the screen. These are the ones we make deliberately on every project.
Architecture
We separate the interface, business logic, data and external services so each can change without rewriting the others. A first release stays small, but its structure leaves room for the next phase.
API design
Endpoints are designed around use cases, return consistent errors and are versioned when they change. The frontend never has to guess what a response means.
Authentication and authorization
Who you are and what you are allowed to do are checked on the server for every request that reads or changes data. Hiding a button in the UI is never the security control.
Database design
Constraints and foreign keys protect relationships, indexes follow the real queries, and related records are loaded together instead of one query per row (the N+1 problem).
Reliability
Operations that must not run twice, such as creating an order or recording a payment, are tied to a unique reference so retries and double clicks do not create duplicates.
Performance
Data that is read often and changes rarely is cached and invalidated when it changes. Pages are code-split so visitors only download what the screen they are on needs.
Security
Input is validated on the server, sensitive endpoints are rate-limited, secrets stay out of the frontend, and dependencies are kept current.
Cloud deployment
Applications are deployed to managed platforms such as Vercel and Render or to your own cloud account, with environment-specific configuration and a repeatable build.

How a project runs
Discovery is usually a call or a meeting where we map the workflow you want to replace, the people who use it and the systems it has to connect to. From that we agree a first release that is useful on its own.
- 01DiscoveryYour goals, users, current tools and constraints.
- 02RequirementsAgreed scope for a first useful release, written down.
- 03ArchitectureData model, APIs, integrations and hosting decided up front.
- 04UI/UXScreens and flows designed and reviewed with you.
- 05DevelopmentBuilt in increments you can see and test along the way.
- 06TestingFunctional, mobile, permission and failure-case checks.
- 07DeploymentReleased to production with environment configuration.
- 08SupportFixes, monitoring and the next phase, as agreed.
Work you can look at
VStitch by Anjali Nanda is a fashion commerce platform we engineered with React, Python and PostgreSQL. Beyond the storefront it handles customised dress orders, backend-verified Razorpay payments, duplicate-request protection, automated PDF invoices and transactional email. The case study walks through the architecture.
This website is our own production system too: a React application prerendered for search engines, served from Vercel, with a Python API on Render behind the contact forms, client portal, lead pipeline and coding courses.
Questions buyers ask us
Do you only work with businesses in Gurugram?
No. We are based in Gurugram and many conversations start with businesses in Delhi NCR, but most of the work happens online, so we also work with clients elsewhere in India and abroad.
Should we build custom software or use an off-the-shelf product?
If an existing product covers your workflow with configuration alone, it is usually cheaper and faster. Custom software makes sense when the workflow is what differentiates you, when you need integrations the product cannot do, or when per-user licensing becomes more expensive than owning the system.
Which technology will you use?
We choose based on the project: React for the interface, and Java with Spring Boot or Python with FastAPI for the backend, depending on your team, existing systems and hosting. We explain the trade-offs before anything is decided.
Who owns the source code?
Ownership of the code and deliverables is set out in the project agreement before work starts, so you know exactly what you will receive at handover.
How do you estimate cost and timeline?
From the workflows, integrations, data migration and quality requirements involved. We prefer to scope a first release that is useful on its own, estimate it properly, and plan later phases from real usage.
Can you take over an existing application?
Often, yes. We start by reviewing the code, hosting and data to understand the risks, then recommend whether to stabilise, extend or replace parts of it.
