Backend & APIs

We build the backend layer that everything else depends on — secure by default, and built to handle the load you’ll actually get.

What Backend & APIs Means Working With Us

Secure-by-Default APIs

Rate limiting and input validation built in from day one, not bolted on later.

Real-Time Socket Architecture

Live updates that stay smooth under real concurrent load, not just in a demo.

Search at Scale

Fast filtering and search indexed for real query patterns.

Third-Party Integrations

Payment, freight, and marketplace APIs wired up reliably.

What We'll Build

Everything That Goes Into a Backend & APIs Project

This is the actual scope of work, not a marketing list — every item below comes from real projects we've delivered.

1

REST or GraphQL APIs

On Node.js, PostgreSQL, or MongoDB — whichever fits your data shape and team.

2

Third-Party Integrations

Payment, freight, CRM, and marketplace APIs wired up and kept in sync.

3

Rate Limiting & Validation

Secure-by-default request handling that doesn’t need to be retrofitted after an incident.

4

Real-Time Socket Infrastructure

Live updates (tracking, chat, notifications) built to stay smooth under concurrent load.

5

Search & Filtering at Scale

Indexes built around real query patterns, not a generic full-text search default.

From Problem to Outcome

What We'll Fix — and What You'll Get Live

If this is already broken

1

APIs Exposed to Abuse

Adding rate limiting and validation to endpoints that currently have none.

2

Slow Queries Under Real Traffic

Diagnosing and fixing the specific queries that degrade once traffic passes demo scale.

3

Fragile Third-Party Integrations

Adding error handling so a third-party API change doesn’t break your app silently.

4

Laggy Real-Time Features

Rearchitecting socket broadcast logic so live updates don’t queue up under load.

5

No Visibility Into Failures

Adding monitoring so you find out about a problem before your users report it.

What you'll have at the end

1

A Secure-by-Default Backend

Not hardened as an afterthought — secure from the first deploy.

2

Documented, Extendable APIs

Documented well enough for your own team or future developers to build on.

3

Monitoring That Catches Problems Early

Alerts before your users notice something is wrong.

4

Infrastructure That Scales With You

A backend built for the traffic you’ll actually get, not just the demo load.

5

Reliable Third-Party Integrations

Payment, freight, and marketplace connections that keep working as those APIs change.
