Multi-location healthcare: delivery unblocked.
An agency drowning in backlog handed us their delivery queue. Dedicated team, their brand, their tools: velocity up 85%.
Users never see your back end, but they feel it: data, logins, payments and background tasks. Senior engineers build it for the traffic you really get, and secure from the first sprint. 4,500+ projects delivered since 2004.

PixelCrayons provides back-end development services: the data, APIs, logins and background tasks your application runs on. We size the system to the traffic you really get. We prefer one well-built application to many small services. Security is built in from the first sprint, and a senior engineer reviews every change. We work direct for brands and white-label for agencies.
The data model is how your information is organised. It outlasts every framework, so it comes first. We agree what you store, how it links together and its rules, in plain English, before code. Changes to it are reviewed like any other change. A back end built this way is easy to extend for years. One rushed past this step gets hard to change within months.
An API is how other software talks to your back end: your website, internal tools or partner systems. We document each one as we build it. Every field and version is written down, using REST or GraphQL, whichever suits the job. Your own team can build on it without asking us what a field means.
We build logins and permissions on proven, tested tools, never home-made security code. People and systems get only the access they need. Passwords and keys stay out of the code. Automated checks scan the software we depend on. Every review checks the OWASP list of common web risks. Security is part of how we build each week, not an audit bought at the end.
This quiet work is what turns a demo into a system you can rely on. Background and scheduled tasks retry safely without running twice. Records stay correct wherever money moves. Errors and logs are easy for your team to read. We test that backups really restore, rather than hope they do.
We size the system to your measured traffic and growth, not to industry fashion. For most businesses that means one well-organised application that one team can run. We split it into separate services only when the numbers show you need to. You get the technical notes, how-to guides and our reasoning in writing. The code sits in your accounts from day one.
Real projects for real clients, with results we can show.
Product names and marks are trademarks of their owners. Naming a technology means our teams build with it. It does not mean a partnership, certification or endorsement.
We sign an NDA. Then we go through your business: its records, rules and traffic, any existing code, and who runs the system after launch.
We confirm the date your proposal arrives. It prices the scope and sets out the system we recommend, with our reasons. Where it's true, that includes 'you don't need microservices for this'.
You confirm the scope, the payment and the access we need. Nothing starts before this.
We settle the data model and the APIs. Then we set up the code, automated checks, test environments and safe password storage in your accounts.
Working, tested APIs on a test site, shown on a call, with real requests against real data.
Prism is the client workspace where your requests, approvals, tasks and weekly reviews live.
Some engagements include Prism, our client workspace, and your proposal says whether yours does. Where it does, your build runs in a workspace you log into: requests, approvals, the task list and the weekly review, beside the repository your team already owns.
One queue, beside the repository your team owns.
Every task has one owner and a date.
Each decision recorded, with the expectation attached.

Shubham consistently excels with punctuality, quick adaptability to feedback, and a proactive drive that enhances system efficiency. He supports the team reliably, even during late hours, without compromising quality. His clear communication and dedication make him a key contributor to our success.
A back end never runs alone. Each service it connects with is one you can buy on its own, from the same senior team.
This page covers the hidden part of your application. If you need the full build (screens, back end and how they connect), see custom web development. Adding engineers to your own team instead? Hire Node.js, Django or Laravel developers by the month.

Know who coordinates your engagement, who owns the work and how to escalate an issue.
All engagements. Roles may be combined and vary with your engagement.
Each one says where it applies and links to its full terms.
We typically respond within four business hours. Eligible engagements can typically start within two to three business days after scope, payment and required access are confirmed.
Business hours are Monday to Friday, 9:00 am to 6:00 pm IST, excluding published company holidays. Typical expectations, not guaranteed service levels.
Full termsApplicable development work includes 30 days of corrective maintenance after production launch.
Development engagements, including partner (agency) development engagements and AI implementations; not marketing services or retainers.
Full termsYour materials remain yours. Bespoke deliverable rights, licences and handover are agreed before work starts.
All engagements.

All engagements. Roles may be combined and vary with your engagement.
Full termsEvery delivery is reviewed before release by QA, your Project or Account Manager and a senior delivery lead, and you then review it against the acceptance criteria agreed at the start. Our specialists use AI to support delivery, with people responsible for reviewing the work. Applicable development work includes 30 days of corrective maintenance after production launch.
Your materials, data and accounts remain yours, and we prefer to work in advertising and analytics accounts you own, with access delegated to our team. Agreed ownership rights in bespoke deliverables transfer under the engagement terms and applicable payment; third-party software and assets keep their licences. We do not withhold customer-owned data or accounts over a payment dispute.
Cancellation, notice and any renewal terms are written into your proposal or statement of work before you accept it. If an engagement ends early, we hand over completed, paid-for work and list any unfinished work separately. For an eligible specialist trial, you can stop within the trial window and pay nothing for eligible trial hours.
Before work starts we agree how often you get updates, what the reports cover and who sends them. You know who coordinates your engagement, who owns the work and how to escalate an issue. For hourly and retainer work, time is recorded in Workstatus, so you can see the time records behind your invoice.
How we handle claims, credentials and your data: group credentials, dated ratings, how case figures are signed off, client permissions and data handling.
Taking over a back end starts with a plain review, not a sales pitch for a rewrite. This is the order we work in, and where a rewrite fits.
Most inherited systems are better than the team that inherited them fears.
Backend web development is the part of your application users never see. It covers the data model, the APIs, logins and background tasks. We size it to your real traffic and build security in from the first sprint. Connecting to other systems, such as CRMs, ERPs and payments, is on our API and integrations page.
Probably not. Microservices split an app into many small services. That makes the code simpler but the running much harder, which only pays off for very large teams. Our default is a monolith: one well-organised application that one team can run. We split it later if the numbers show a need. If we think you need services, we'll explain why in writing, using your figures.
Node.js and TypeScript, PHP with Laravel, and Python for data-heavy work. We use PostgreSQL or MySQL databases and host on the major clouds. We choose based on what your team can run and hire for, and prefer proven tools with plenty of developers. Where we lack senior depth in a technology, we say so and point you elsewhere.
As part of everyday work, not a certificate bought at the end. We use proven login tools and give only the access needed. Passwords stay out of code, and automated checks scan the software we depend on. Every review checks the OWASP list of common risks. Personal data is handled to laws such as GDPR. We won't promise 'unhackable', but if you need an audit or penetration test, we build to pass it.
Yes, taking over back ends is a regular part of our work. We start with a plain review of the data model, how releases work and the risky areas. Then we make it stable before adding to it: tests on the key paths, new passwords and keys, and checked backups. If a rewrite costs less than step-by-step fixes, we show our reasons and you decide.
Your materials, data and accounts remain yours. Agreed ownership rights in bespoke deliverables transfer under the engagement terms and applicable payment; third-party software and open-source dependencies keep their licences. We don't withhold customer-owned data or accounts over a payment dispute. Credentials live in your vault, and schema documentation and runbooks are kept as we build.
Yes. Many agencies use us as their backend development agency under their own brand, with an NDA. You keep your tools and client calls; our engineers do the work. We don't approach the clients you introduce to us for direct business, through the work and for twelve months after the last assignment for that client ends, and it's written into the agreement.
A fixed quote to build the core, priced from the data up, or to take over one someone else built. Then a retainer to run it. Connecting the core to other systems is the API & Integrations row.
