An engineer in your team while you hireAn extended dev team, month to monthTell us your idea in plain words and a first interactive draft follows, usually the same day. Behind it is a senior engineering team running its own AI coding-agent fleet, so the draft gets finished to production grade, with an engineer reviewing and merging the work.

“Indra led a rebuild of our multi-step checkout system, significantly improving both stability and user experience.”
He was proactive, pragmatic, and easy to work with—taking full responsibility for delivery end-to-end and iterating quickly while keeping the implementation clean and scalable. He rebuilt the frontend using Vue 3 and Vuetify, implemented Pinia for consistent state management across the multi-step flow, and integrated Stripe Elements for secure and seamless payment processing. The final result was a faster, more maintainable checkout experience that felt significantly smoother for users.
Live in production
A charter booking widget, a mobile ordering and kiosk app, a dental practice marketplace, and a multi-tenant SMS service running inside HubSpot, live for businesses in the US and Asia today.
Multi-model code review
Models from different families review each change, and an engineer decides what ships.
A real person, on your hours
A real person reviews every submission and stays with your project, working to your timezone, not ours.
What we do
Pick the door that sounds like you. Each one leads to a page written for your situation.
Your own ops system, run by us
Orders, stock or scheduling still live in spreadsheets. We build a system around how your team works, connect it to the tools you already use, and keep it running.
See the ops systemTake the repetitive work off your team
WhatsApp enquiries, orders copied between systems, reports pulled from portals. We build each automation, run it, and fix it when things change.
See automationsTake your prototype to production
It works in the demo but not with real users. We sort out login, payments, data and hosting, then hand it over or keep it running.

ONGOING DEVELOPMENT
Launching is the start. If your product needs steady shipping after that, a monthly pod keeps it moving. You buy outcomes, not an hourly meter. Pods also take on connected-systems work: your tools built into one connected system, progressively.
