Hire a API Developer

A dedicated API developer who builds the connections your product runs on

A logistics startup came to us with a working app and a problem nobody on their team could solve: their Stripe billing, their shipping rates, and their internal dashboard all spoke different languages, and nothing stayed in sync. They did not need a finished project handed back. They needed one developer who lived inside their codebase, joined their standups, and owned the API layer week after week. That is the kind of engagement this page is about.

How the Engagement Works

REST and GraphQL endpoints built to a spec

Your developer designs routes against an OpenAPI contract first, so your frontend team and your mobile team can start building against the API before the logic is even finished. No guessing at response shapes.

Authentication that holds up

OAuth flows, token refresh, scoped permissions, and the boring edge cases that break in production at 2 a.m. Your developer handles the parts most tutorials skip, like rotating secrets and revoking access cleanly.

Third-party integrations that stop breaking

Connecting to Stripe, Twilio, QuickBooks, or a partner's API where the docs are wrong half the time. Your developer reads the actual responses, handles the retries, and builds around rate limits instead of pretending they do not exist.

Endpoints that stay fast under load

When a single dashboard call fans out into nine database queries, your developer finds it and fixes it. Caching, pagination, and query batching tied to the requests that actually slow your users down.

Documentation your team can read

Every endpoint shipped with a Postman collection and an OpenAPI file your other developers can import and test in minutes. New people on your team stop pinging the original author to ask how things work.

Versioning that does not break clients

When the API has to change, your developer ships a new version and keeps the old one alive on a deprecation timeline. Your mobile app from eight months ago keeps working while you migrate.

Why Hire from Aneri Developers

The same developer, not a rotating cast

The person you onboard in week one is the person still shipping in month six. We do not quietly swap your developer for someone cheaper once the contract is signed, because the context they build up in your codebase is the whole point.

Your code is yours from day one

Everything your developer writes lands in your repository under your account. There is no escrow, no holding the work hostage, no license you have to keep paying to use what you already paid to build.

Real overlap with your working hours

Our developers shift their day to hold several hours with US Eastern and Pacific mornings. You get live conversation when you need it, and the rest of the time the work moves forward while your office is closed.

NDA and contract before any code

We sign your NDA and a written agreement covering IP, scope, and termination before your developer touches the repository. No verbal arrangements, no assumptions about who owns what.

A replacement if the fit is wrong

If the developer is not working out, you tell us and we match you with someone else. We would rather move quickly on a bad fit than have you stuck paying for a relationship that is not clicking.

Visible progress every week

You get a short written update each week with what shipped, what is blocked, and what is next, plus a Loom walkthrough when something is worth showing. You never have to ask where things stand.

Engagement Models

Full-Time

176 hrs/month

One developer focused entirely on your API work, in your standups and your sprint board every day. This is the right call when the API is a moving part of your roadmap, not a one-time job.

Part-Time

88 hrs/month

Half a developer's month, useful when you have steady API work but not enough to fill a full schedule. Good for maintaining and extending an existing service without overcommitting.

Hourly

Flexible

You pay for the hours your developer actually works, logged and visible to you. This suits unpredictable workloads, a fix here, an integration there, where a fixed monthly block would either sit idle or run short.

Team Hire

More than one developer when a single person cannot cover the surface area, for example a backend engineer plus someone on integrations. We size the group to the work and keep them coordinated.

How to Hire a API Developer

From first contact to your developer writing code — here is how it works.

Get Started
1

First Conversation

We talk through what your API needs to do, what is already built, and where it hurts right now. By the end of this call you know whether your problem is a fit for a dedicated developer or whether you actually need something else.

2

Matching You With a Developer

We put forward a specific developer whose background lines up with your stack, and you interview them directly. You are choosing a person you will work with daily, so the decision is yours, not ours.

3

Onboarding Week

Your developer gets access to your repository, your docs, and your team channels, then spends the first days reading the existing code instead of writing new code. They map how your current endpoints and auth work before changing anything.

4

First Sprint Plan

You and your developer agree on the first two weeks of work and what done looks like for each item. The first sprint is deliberately scoped small so you can judge the working relationship on real output, not promises.

5

Weekly Delivery Rhythm

From there the developer works inside your sprint cycle, joins your standups, and ships against the backlog you prioritize. You stay in direct contact over Slack, with a written recap and demo each week.

Frequently Asked Questions

You pay for the hours your developer logs, and those hours are visible to you, not estimated after the fact. It fits work that comes in waves, like a burst of integration work followed by a quiet stretch. If the workload turns steady, most clients move to a monthly block because it is simpler to plan around.

Our team is based in India, and our developers shift their schedule to overlap several hours with US Eastern and Pacific mornings. That window is for live calls, pairing, and quick decisions. Outside it, work keeps moving, so you often wake up to progress made overnight.

If you have one small, well-defined API job with a clear finish line, a fixed-scope project is a better fit than paying for ongoing time. This model pays off when the work is continuous and the developer's growing knowledge of your codebase matters. We will tell you on the first call if we think you are about to overbuy.

You do, completely, from the first commit. Your developer works in your repository under your accounts, and the NDA and contract we sign before starting spell out that all IP is yours. There is nothing you have to license back or buy out later.

Tell us and we will match you with someone else, no drawn-out process. We keep the first sprint small on purpose so a poor fit shows up early, while the cost of switching is low. A mismatch caught in week two is far cheaper than one ignored until month four.

You talk to your developer directly over Slack during the overlap hours, not through a layer of account managers. Each week you get a written summary of what shipped and what is blocked, plus a short Loom recording when a demo helps. The goal is that a twelve-hour gap never leaves you guessing.

Talk through the API developer you need

Tell us what your API has to connect and where it breaks today, and we will line up a developer who can own that layer. The first call is a conversation about your stack, not a sales pitch.
