Backend & API development

Backend and API development that lasts

I build the backends that web and mobile apps run on: secure APIs, well-designed databases and integrations with payment providers and third-party tools — documented so any future developer can pick them up.

This is for you if…

  • You need a backend for a web or mobile app
  • Your systems don't talk to each other
  • Your current API is fragile, slow or undocumented
  • You're planning more than one app on the same data

What you get

REST APIs

Clean, versioned endpoints documented with OpenAPI / Swagger.

Database design

PostgreSQL schemas and migrations designed around your data, not bolted together.

Authentication & roles

Secure sign-in, permissions and data separation between users or organisations.

Integrations

Payments, email, messaging and third-party APIs connected reliably.

Background jobs

Retries, scheduled tasks and queues so work isn't lost when something fails.

Tests & CI

Automated tests and deployment pipelines, so changes ship safely.

Maternal Care Dashboard

A backend and web dashboard that lets maternal and newborn care teams record patient data and act on automatic risk alerts.

“Our maternal programme was running on paper registers and spreadsheets. Within about two weeks Samarth gave us a dashboard that flags high-risk readings and puts them in a queue someone owns.”

Common questions

Can one backend serve both a website and a mobile app?
Yes, and it should. I design APIs so a dashboard, website and mobile app can all share the same backend and data.
Which backend technologies do you use?
Mostly Node.js with Express and Spring Boot, on PostgreSQL. I pick whichever fits your project and team best, and document it either way.
Can you work on an existing backend?
Yes. I start with a short paid code review to understand the system and flag risks, then fix, extend or gradually improve it.
