Custom web applications built to scale
From internal tools and dashboards to customer-facing portals — we build custom web apps that close the gaps commercial software leaves behind. No forced workflows, no monthly per-seat pricing creep.

What we build
Role-based access systems for partners, customers, or staff — each role sees only what it needs.
Analytics and operational data tools that turn raw data into decisions your team can act on.
Back-office automation replacing spreadsheets — validation, history, and reporting built in.
Multi-tenant subscription platforms — from zero to your first paying customer.
React frontends wired to third-party integrations — payments, CRMs, ERPs, and more.
Modernising outdated systems into a maintainable stack without disrupting the business.
// technical depth — not just CRUD screens
Web app capabilities
SSR, SSG, and client-side rendering — the right strategy chosen per screen, not applied blindly.
JWT, OAuth, and session management with role-based access control baked into every route.
WebSockets, Server-Sent Events, or polling — whichever fits the data freshness your app needs.
Playwright automation covering critical user flows before every release, not just at launch.
Core Web Vitals and lazy loading tuned so dashboards stay fast even with heavy datasets.
AWS, GCP, and Vercel with CI/CD pipelines built by GitHub Actions or Docker.

Apps we've built
Custom warehouse management system replacing manual spreadsheets — inbound/outbound tracking and daily reconciliation reports for a 3PL operation.
Multi-role portal for an NBFC lender — separate workflows for applicants, loan officers, and admins across the full loan lifecycle.
Multi-tenant recruitment SaaS taken from zero to its first paying customer in 14 weeks — job pipelines, scorecards, and interview scheduling.

Built for your workflow, not a generic one
Tailored to your actual workflow — no generic templates or drag-and-drop compromises.
Type-safe across every layer — frontend, backend, and shared contracts — so refactors stay safe.
Performance is built in from inception, not bolted on when dashboards start to feel slow.
OWASP compliance, proper auth, and data isolation between tenants and roles, standard.
We build custom web applications — from internal tools and dashboards to customer-facing portals — for founders and enterprises across India, the UK, the US, and beyond. When a workflow is unique, data is sensitive, or SaaS subscription costs would exceed a custom build within two to three years, a purpose-built app pays for itself. Every project is custom-coded, owned by you, and handed over with a codebase your own team can actually pick up.
// client words — custom web apps
They replaced four different SaaS tools we were paying for with one custom app. It does exactly what our workflow needs — nothing more, nothing less.
The codebase they handed over was the cleanest I've seen from an external vendor. Our internal team picked it up within a week. Architecture docs included.
Our portal handles 8,000 active users daily without issues. The load testing they did pre-launch caught a database bottleneck we'd never have spotted ourselves.

When workflows are unique, data is sensitive, or SaaS subscription costs would exceed the cost of a custom build within 2–3 years.

Yes — i18n support via next-intl or react-i18next, RTL support, and CMS-managed translations are standard options.
