Services

Web application development

Platforms, dashboards and portals that hold up under real load.Custom web applications built on React, Next.js and TypeScript — architected for speed, search visibility and the traffic you expect in year three.

Most business software fails quietly. It works for the first hundred users, then the dashboard takes nine seconds to load, the invoicing job starts timing out, and every new feature breaks two old ones. We build web applications that do not get to that point.

ByteCrux designs and engineers custom web platforms end to end: the data model, the API layer, the interface your customers touch, and the deployment pipeline that gets it live. We work primarily in TypeScript across the stack, which means one language, one set of types, and far fewer of the integration bugs that eat project timelines.

Whether you need an internal operations tool that replaces a sprawl of spreadsheets, a customer-facing SaaS product, or a marketing site that actually ranks, we scope it honestly and ship it in working increments you can see every week.

What you get

  • Sub-second page loads and Core Web Vitals in the green
  • Typed end to end, so refactors do not become outages
  • Automated tests and CI on every pull request
  • Documented handover — you own the code and the accounts

Capabilities

Web applications we deliver

The concrete pieces of work an engagement is made of.

Custom SaaS platforms

Multi-tenant products with authentication, role-based permissions, billing integration and an admin surface your team can operate without a developer.

Internal tools & dashboards

Operations software that consolidates spreadsheets and manual processes into one auditable system, with reporting that loads instantly.

Customer portals

Self-service areas where your clients track orders, download documents, raise tickets and pay invoices without emailing your team.

API design & integration

REST and GraphQL services, third-party integrations, payment gateways, and the webhook plumbing that keeps separate systems in sync.

Performance & SEO engineering

Server rendering, edge caching and Core Web Vitals work so pages load fast and search engines can index everything that matters.

Legacy modernisation

Incremental migration off ageing PHP, jQuery or WordPress stacks — without a risky big-bang rewrite that stalls your business.

FAQ

Web applications — common questions

Straight answers on timelines, cost and ownership.

How long does it take to build a web application?

A focused MVP typically ships in 8 to 12 weeks. A larger platform with multiple user roles, integrations and billing usually runs 4 to 6 months. We break every project into two-week increments, so you see working software early rather than waiting months for a single reveal.

What does a custom web application cost in Ahmedabad?

Scope drives cost far more than location does. A well-defined MVP generally starts around ₹6–10 lakh, while multi-role platforms with complex integrations run higher. We provide a fixed-scope estimate after a discovery call rather than a number pulled from a price list.

Do you work with existing codebases?

Yes. A large share of our work is taking over or rescuing an existing application. We start with a paid technical audit that documents the architecture, risks and quick wins, then agree a plan before touching production code.

Who owns the source code?

You do, entirely. Code lives in your Git organisation from day one, infrastructure runs in your cloud accounts, and there is no licensing arrangement that ties you to us after handover.
