Custom PHP development · Srinagar, India
Turn a defined calculation or business task into a usable web tool. I plan the inputs, rules, results and important error cases, then build the agreed interface and processing. Share sample inputs and expected results so we can check the rules before development.

Start with the requirement
This service fits a calculator, quotation aid, structured enquiry workflow or small administration tool with understandable requirements. It can also cover a repair to an existing PHP application when the source and runtime are available. Complex integrations, sensitive workflows and unclear business rules need a separate feasibility stage.
What the work involves
Your proposal identifies which deliverables are included, who supplies the material and how the work will be accepted.
We document inputs, allowed ranges, formula ownership and the meaning of the output. The business supplies approved rules and representative examples. Where a calculation touches regulated or specialist decisions, the relevant professional must approve the method; code alone cannot establish the validity of the underlying advice.
The interface explains required values, units and common mistakes. Results should have useful labels and an understandable recovery path when input is invalid. Responsive layouts, keyboard operation and language requirements are considered with the calculation rather than added after the successful example is built.
The technical scope defines what is processed in the browser, what reaches the server and whether information is retained. Necessary server-side validation and access checks are planned for the actual workflow. External APIs require review of permissions, limits, failure behaviour and ongoing provider costs.
Meaningful acceptance examples cover valid input, boundaries and important failure cases. Handover can include source, deployment notes, runtime dependencies and a description of the agreed rules. If a formula or provider changes, someone needs responsibility for reviewing and releasing the update.
Your first review
Bring sample inputs, expected results and the person who approves the calculation or workflow. The first review covers a valid case, a boundary value and an invalid input.
The result explains its assumptions; validation and error messages match the agreed rules and the reviewer records open questions.
Send the starting brief on WhatsAppA concrete starting point
A visitor enters an agreed set of project values and receives an indicative estimate with its assumptions shown. The business decides whether the result is informational or requires staff confirmation. Review includes missing input, out-of-range values and a boundary example.
Illustrative planning example. The service proposal defines your actual deliverables.
Before committing
An established component may be enough for a standard requirement. Custom work is justified when the rules, presentation or integration need it and the business can support maintenance. The proposal explains that tradeoff and avoids building a large application for a small content problem.
Some tools can run without an account or stored personal information. Others require controlled records and user roles. We define the purpose, retention and access before adding collection, rather than automatically creating a database entry for every interaction.
Inspect the work
Ratib Calculator is an independent Arabic salary and social-insurance calculator I own and develop. Inspect its input controls, result explanation and methodology links as a web-tool example. Your own calculation needs approved rules and reference cases.
Acceptance
Agree the test method, recipient and sample details before checking messages, bookings or transactions.
Budget and responsibilities
A prototype, a public calculator and a role-based application have different development and maintenance requirements. The quote identifies the rules, screens, integrations, data handling and tests included. Hosting, external API charges, specialist formula review and ongoing changes are separate unless named in the scope.
Published pricing & exclusionsQuestions before you start
Need to discuss your existing setup? Start with the public URL and the problem you want to solve.
Send a project brief by emailYes, after defining the approved inputs, rules, assumptions and result wording. If a staff review is required before a binding quotation, the tool should make that clear.
I first review the available source, runtime, dependencies and symptoms. The proposal identifies the repair boundary and any unsupported components or missing documentation that affect feasibility.
Only when storage is needed and explicitly scoped. We agree the data purpose, access and retention. A tool that can perform its task without retaining personal information should not collect it merely by default.
Source delivery, third-party dependencies and deployment instructions are specified in the proposal. Licensed components retain their own terms, and ongoing rule or integration changes need an agreed maintenance owner.

Background, working approach & contact detailsRelated work
Turn a customer task into screens you can review before development. I map the steps and prototype the important input, error and completion states. Send the task, current interface and examples of what people need to do.
Scope, examples & questionsGive visitors usable pages in each agreed language. I build matching page links, navigation and forms, then check readable layouts and the enquiry journey. You or an agreed reviewer approve the wording. Share the languages, priority pages and who will maintain each version.
Scope, examples & questionsGet a clear plan for updates, backups and the website tasks that need regular attention. I first review the existing site and access, then agree the work, support hours and checks after each change. Send the URL and what currently needs attention.
