Custom Web Applications
When a business process depends on disconnected tools or repeated manual steps, a custom application can give people one place to complete the work. KD Dziekan develops web applications around the users, information, and decisions involved in that process.
Projects can include dashboards, booking workflows, business systems, and API integrations. We work with businesses in Chicago and nearby suburbs as well as clients across the United States. We start by understanding the workflow before deciding what should be custom-built.
A web application may fit when customers or staff need to enter information, track progress, or interact with connected systems through a browser. It is different from a marketing website: user roles, data, and business rules shape the project. We can also discuss whether configuring an existing tool would address the problem with less custom work.
We map the steps in the current process, who performs them, and where information moves between tools. The initial scope identifies the smallest useful set of features, exceptions that need handling, and requirements that can be deferred.
Screens, forms, and navigation are designed around real tasks. A dashboard should show information someone can act on; a booking flow should make the next step understandable. Review points let you assess those workflows before development advances.
The application build connects the agreed interfaces to business logic and data. Where another system is involved, we review its API access, documentation, and limitations before defining the integration. Availability of an API does not automatically make every feature possible.
Checks should cover normal tasks, invalid inputs, and important failure cases. Deployment, account access, and maintenance responsibilities are agreed as part of delivery. Later features can be planned separately once the initial application is in use.
Identify who needs access, what information they should see, and what they may change. Sensitive data, retention requirements, and any regulatory obligations need an explicit discussion before an estimate; no compliance certification is implied by a custom build.
Third-party subscriptions, API permissions, request limits, and existing data quality affect feasibility. Bring details of the tools that must connect and explain whether information needs to move in one direction or stay synchronized.
Trying to replace every process at once can make a project difficult to define. Prioritize one workflow and agree how it will be reviewed. Optional features, rollout support, and long-term operating responsibilities should be visible in the scope.
CRM and API integrations are part of the existing service offering. A specific connection depends on the other tool providing suitable access and documentation. We review permissions, data formats, limits, and required subscriptions before confirming that integration in the scope.
A browser-based application can suit work across computers and phones without a separate app installation. A mobile app may be appropriate when the intended experience depends on device features or repeated use on a phone. We discuss the user tasks before recommending an approach.
Further development can be scoped after launch. It helps to identify likely future needs early, while keeping the initial release focused. New workflows, integrations, and changes to business rules should be reviewed for their effect on the existing application.

Describe the process you want to improve, who uses it, and the systems involved. That gives us a starting point for discussing feasibility and an estimate.
