What clients usually need
A clear scope, a usable product, and the technical pieces behind it.
Custom backend and API development for authentication, realtime data, secure rules, storage, cloud functions, REST APIs, GraphQL APIs, notifications, maps, geofencing, payments, and admin dashboards.
- Authentication, roles, secure data rules, storage, cloud functions, APIs, webhooks, and server workflows.
- Realtime feeds, chats, live maps, Mapbox, geofencing, notifications, file uploads, payment events, and admin-ready APIs.
- Data models planned around product behavior, reporting needs, performance, integrations, and future changes.
Tables, collections, indexes, relationships, and access rules are planned before the app depends on them.
Chat, trip status, feeds, live maps, presence, and notification triggers can be connected to realtime data.
Cloud functions, Edge Functions, Node.js APIs, webhooks, scheduled tasks, and integrations can support the product behind the scenes.
What we handle
Practical service depth for a real product build.
The work is shaped around the decisions, screens, backend rules, and launch details clients usually need before the product can be trusted by users.
Auth and roles
Email, phone, social login, permissions, account states, and admin roles can be built around the product model.
Database structure
Tables, collections, indexes, relationships, and access rules are planned before the app depends on them.
Realtime features
Chat, trip status, feeds, live maps, presence, and notification triggers can be connected to realtime data.
Server logic
Cloud functions, Edge Functions, Node.js APIs, webhooks, scheduled tasks, and integrations can support the product behind the scenes.
Operational visibility
Admin dashboards and reports make backend data useful to the business, not just the development team.
How the build moves
From first conversation to launch and iteration.
The delivery process keeps scope, product decisions, backend details, QA, and release requirements visible from the beginning.
