Full-Stack Web Application Development

Every hard part of a web product, from sign-in and payments to a schema that migrates and analytics that answer real questions, is something we already run in production on our own platform.

What we build

Full-stack web apps: what we take on

Web applicationsFront to back: accounts, roles, a Postgres database, background jobs and an admin.
PaymentsRazorpay checkout, webhooks, refunds and reconciliation, with signed webhooks and replay protection.
Odoo modulesCustom Odoo 19 apps. Our POS UPI QR module is live on the Odoo Apps Store.
Internal dashboardsMulti-tenant tools where one client can never see another client's rows, with CSV export.
APIs & integrationsConnect CRMs, payment gateways, marketplaces and spreadsheets without anyone copying data by hand.
AnalyticsEvent tracking that answers the question you actually asked, instead of dashboards nobody opens.

Razorpay module for an AI-agent platform

Eleven Razorpay commands for AI agents, with refunds and link creation held for human approval. Razorpay has no idempotency header on refunds, so the module writes a payload hash into the refund notes to make a retry safe.

We write the acceptance checks with you, then fix the price and the delivery date.

Build, tested every step

Nothing reaches you until it passes the agreed checks. You get progress updates without having to ask.

Handover

Code, checks, README and setup steps, so you can run it and redeploy it without us.

FAQ

Full-stack web apps: common questions

What stack do you use?

Usually plain HTML/CSS/JS or a light framework on the front, Node or Python on the back, Postgres (often Supabase) for data, and Netlify or similar for hosting. We pick the smallest stack that does the job.

Can you integrate Razorpay?

Yes. We run Razorpay in production, published a Razorpay module for an AI-agent platform, and built an Odoo POS module that confirms UPI payments automatically through Razorpay webhooks.

Will I be able to run it without you?

Yes. Every handover includes a README, the setup steps and the tests, so you can redeploy it yourself.

Have something to build?
