Back Ends That Stay Fast After the Table Fills Up
A back end rarely fails on the day it ships. It fails the month the orders table passes a hundred thousand rows and a page that returned in 80 milliseconds starts taking nine seconds, or the day a payment provider retries a webhook and your customer is charged twice. We build the server half so those two failures are designed out rather than discovered.

Everything Included in Back-End Development
No vague retainers. Here is exactly what lands, and what it is for.
Data Model and Schema
Entities, relationships and the constraints the database itself enforces — foreign keys, unique indexes, not-null. Indexes chosen from the queries you will actually run, and every change shipped as a versioned migration.
REST API and Contract
Versioned endpoints with an OpenAPI document your front-end team can generate types from. Input validated at the boundary, consistent error shapes and status codes, pagination on every list that can grow.
Authentication and Authorisation
Sessions or tokens with expiry and rotation, passwords hashed with Argon2 or bcrypt, reset flows that do not leak which addresses exist. Permissions checked on the server for every request, not inferred from the interface.
Integrations and Payment Webhooks
Stripe, CRMs, accounting and shipping APIs wired in with signature verification, idempotency keys and exponential backoff. A retried webhook lands once, and a call that fails three times goes to a queue somebody can see.
Query and Index Optimisation
Every slow endpoint traced to its query plan. N+1 loops collapsed into joins or batched loads, missing indexes added, connection pooling configured, and results cached in Redis where the data tolerates being seconds old.
Deployment, Logging and Handover
A pipeline that runs the tests and the migrations before anything ships. Structured logs with a request ID, error tracking, secrets in environment variables rather than the repository, and a written runbook for the failures you will meet.

Situations we build this for
The brief we get most often, and why this service rather than another one.
The Front End Has No Server
Your React app or mobile build works against mock data and has nowhere to send it. We design the schema, ship the endpoints and hand over an OpenAPI contract your team builds to.
Fast in Test, Slow in Production
The dashboard returned instantly with two hundred rows and times out at two hundred thousand. That is almost always an N+1 loop and a missing index, and both are measurable in an afternoon.
Authentication Was Written by Hand
Somebody rolled their own login in a hurry: tokens that never expire, a reset link that works forever, permissions checked in the browser. This is the work we are asked to replace most often.
A Customer Was Charged Twice
Your payment provider retried a webhook it never saw acknowledged, and the handler ran twice. Idempotency keys and a record of processed events fix it, and no amount of front-end work will.
- REST APIs for web and mobile front ends
- Database architecture, schema design and migrations
- Authentication, roles and permission systems
- Payment gateway and Stripe webhook integrations
- Third-party API and CRM integration layers
- Slow query, N+1 and indexing rescue work
- Background jobs, queues and scheduled tasks
- Legacy PHP back ends rebuilt in Laravel or Node.js
- Server-side security hardening and dependency patching
Why businesses buy this
Not adjectives — the mechanism behind each one.
The Database Enforces It
Foreign keys, unique constraints and not-null rules live in the schema rather than in application code. A second client, a script or an import cannot then write the row your validation would have rejected.
Indexes From Real Queries
We read the query plan before adding an index, because an index that matches no plan costs write speed and buys nothing. The ones we add turn sequential scans into lookups you can measure.
A Retry Lands Once
Every write endpoint takes an idempotency key and records the events it has already processed. Networks drop acknowledgements and providers retry by design, so the safe assumption is that each request arrives more than once.
Permissions a User Cannot Reach
Every role check runs on the server against the session, not on a hidden menu item. Anyone can open developer tools and call the endpoint directly, which is how most access-control breaches actually happen.

You have a front end that needs an API behind it
