Custom Web & Application Development

Our development experience includes complete custom applications as well as targeted enhancements to existing websites and software. Projects may involve a public-facing website, an administrative application, a customer portal, or a combination of all three.

Application Development

Database-driven websites and applications.

Administrative and management portals.

Customer and member accounts.

Role-based and multi-level user permissions.

CRM and customer-management tools.

Subscription and recurring-service systems.

Forms, document workflows, and electronic signatures.

Calendars, scheduling, and resource management.

Dashboards, reporting, and data exports.

Automated email and notification systems.

File, image, and document management.

AI-Assisted Development

We use modern AI-assisted development tools, including ChatGPT, Claude, and Gemini, alongside traditional development and debugging workflows. We use them for code review, troubleshooting, refactoring legacy applications, documentation, exploring implementation approaches, and accelerating repetitive development tasks while still reviewing and validating the resulting code and behavior.

Existing Systems & Modernization

Not every project should be rebuilt from scratch. We regularly work with established applications where the better approach is to understand what already works, identify the areas causing problems, and improve them incrementally.

That can include adding new features, rebuilding individual sections, updating interfaces for modern devices, replacing outdated integrations, improving database processes, correcting performance problems, or connecting an older application to newer services.

From Requirements to Production

Our work typically covers the complete development cycle: understanding the business requirement, defining how the feature should work, planning data and interface changes, developing in a separate environment, testing with users, resolving issues, and moving the completed work into production.
