Backend development — the server side of websites and mobile apps
Backend development means building the server side of a website or app: accounts, payments, data exchange with other services via an API. A new project or work on existing code — describe the job, and backend developers will send responses. Or pick one yourself — by portfolio and client reviews.
Backend developers
How much backend development costs
What affects the price
Amount of business logic
A few endpoints for a contact form and a system with user roles, orders and reports are projects of very different scope.
Number of integrations
Every third-party service — payments, delivery, CRM, accounting — has its own documentation, test mode and errors that need handling.
New project or someone else's code
Work on an existing backend starts with reading the code, and without documentation or tests that sometimes takes longer than the change itself.
Load and data
Peak loads, large volumes of data or a migration from an old database call for caching, queues and separate testing.
Docs, tests and deployment
An OpenAPI description of the API, automated tests and deployment to a server may be included in the price or paid for separately.
Prices come from specialists' profiles on Nexperity and update automatically. You agree the final price with the specialist directly.

How to choose a backend developer
- 1
Similar projects, not screenshots
A backend developer's work does not show in screenshots. Ask about a similar project: which integrations it had, which database, how tests and deployment were set up.
- 2
A stack for the years ahead
Node.js, Python, PHP or Go is also a question of who will maintain the code later. Ask why the developer recommends that language and framework.
- 3
API docs along with the code
Agree that you will get API documentation, for example in OpenAPI format, so that another developer can work with the backend too.
- 4
Data security
Ask how passwords and access keys will be stored, who will see users' personal data, and whether the database will be backed up.
- 5
Code in your repository
The code repository, the server, the database and third-party service keys should be registered to you or your company, not to the developer.
What to put in the order
What the product is and who it is for: a website, a mobile app or an internal service
What is already done: frontend, mockups or existing code — with or without documentation
Which services need connecting: payments, delivery, CRM, accounting, email
The programming language, database and hosting you want, if you have already chosen them
How many users and how much data you expect at launch
Payment, the deadline you want and whether you need support after launch
Questions about Nexperity
How Nexperity works — separately for clients and for specialists
For clients
Nothing. Searching for specialists, sending requests, posting orders and receiving responses are free.
No. You agree the price and the payment method with the specialist and pay them directly. Nexperity does not take payments and is not a party to your deal.
A request goes to one specialist — from their profile. An order is posted for everyone: specialists send you responses, and you choose which one to accept.
How the specialist will do the task, a price — fixed, a range, hourly or “on request” — and, optionally, an estimated timeline.
30 days from publication: all that time it is visible in the feed and specialists can send responses. The exact end date and time are shown on the order in your account. From that moment the order is closed and a response can no longer be accepted. You can cancel it earlier, and if no specialist turned up, post a new one.
Yes: you can hide your name and photo in an order. The anonymity lasts until acceptance — the specialist whose response you accept sees your name and photo. The task description is public: anyone visiting the site can read it.
Only after acceptance — when you accept their response or they accept your request. And only the contacts you chose to show.
After acceptance you see the contacts the specialist chose to show, and they see the ones you chose. You can also message on Nexperity when the chat is on: on an order you decide that, on a direct request the specialist does.
Once the work is done, mark the order or the collaboration completed in your account — then you can say whether you recommend the specialist. A review can only be left for a collaboration that happened through Nexperity: one per specialist, which you can change or delete at any time.
For specialists
Nothing for now: this is the free period, and no subscription is needed yet. Nexperity takes no commission on deals — you settle with the client directly.
Sign up, fill in your specialist profile and add your services — each with a category, a description and a price. Once the profile is complete, it appears in search and on the category pages.
Two ways: clients send you requests from your profile, which you can accept or decline; and you see public orders in your categories in your account and can respond to them.
You describe how you will do the task and give a price and, optionally, a timeline. The client compares responses and accepts one.
Contacts set to “Public” are visible to everyone on your profile. A client sees contacts set to “After connection” once you accept their request or they accept your response. “Hidden” ones are not revealed in new connections: a contact already revealed to a client stays visible to them.
Each service has a fixed price, a range, an hourly rate or “on request”. Prices show on your profile and in search results, and you agree the final price with the client.
Through search and the category pages of your services. The order depends on your clients' reviews — how many of them recommend you — and in search also on how well your services match the query.
A photo, a description, your region and way of working — online or in person — your contacts and a portfolio: photos of your work, each with a short caption if you like.
A client leaves a review after completed work, and only for a collaboration through Nexperity: they say whether they recommend you and may add a few words. Each client counts once, however many times you work together.
