Custom Web Application Development

Get a platform launched. Make an unreliable system usable. Work directly with Bill Vivino on the web application, backend, and integrations that your business depends on.

Build a new business platform, take over an unfinished application, or improve the system your team already uses.

Software for the Work Your Business Does

This is application development: the screens, workflows, permissions, data, and integrations behind a working product. Bill can take technical responsibility for an agreed system, from architecture and implementation through testing, deployment, and a documented handoff.

  • Custom web applications and operational dashboards
  • Multi-role workflows, authenticated access, and notifications
  • React and Next.js interfaces connected to backend services
  • Node.js APIs, PostgreSQL, SQL Server, and Firebase systems
  • Data integration, reporting, and automated refresh workflows
  • Existing-codebase stabilization and continued development

Build, Stabilize, or Connect Your Platform

Launch a New Platform

Turn a defined business workflow into an application people can use. Plan the first release around its users, data, integrations, and operating requirements, then build and test it in reviewable stages.

Make an Existing System Usable

Start with the failures blocking users or delivery. Inspect the application and its dependencies, agree the priority fixes, and decide what to retain, repair, or rebuild. A troubled system does not automatically need a complete rewrite.

Connect the Systems Around It

Bring APIs, databases, reporting, and mobile clients into the same product plan. Address access rules, synchronization, failure handling, and ownership at the boundaries between systems.

Delivery Example: An Internal Reporting Platform

An anonymous example from Bill's software consulting experience.

An internal reporting system brought together multiple data sources in an analytics dashboard. Bill designed and deployed the dashboard and its supporting cloud-data workflows.

What Bill Owned

Responsibilities included data integration, role-aware access, automated refresh workflows, performance work, documentation, and technical handoff. The engagement covered the system behind the dashboard as well as the interface.

What Was Delivered

A deployed internal analytics dashboard, connected to its data sources, with access controls and refresh workflows, plus documentation and a technical handoff. This is the kind of end-to-end responsibility a business application needs beyond its initial screens.

Questions About Your Existing Application

Can Someone Take Over Our Unfinished Application?

Yes. Bill can review an inherited codebase and take responsibility for an agreed application or backend. Start by establishing what builds, what users can complete, and what blocks the next release. The review covers source code, hosting, data, integrations, access, and deployment. A takeover estimate depends on that evidence and the business workflows still to be completed.

Should We Rebuild or Repair Our Software?

Repair is a candidate when the core workflows and data model still fit the business and failures can be isolated. Rebuilding a component may make sense when the current design cannot support a required workflow, access rule, or platform. Compare those options after investigation, including data migration, continued operation, and release risk. Read the repair-versus-rebuild approach.

Can We Improve One Part Without Replacing Everything?

Often, yes. Scope a defined workflow, API, dashboard, or integration, then trace what depends on it. Agree the behavior that must keep working, the checks required before release, and who owns the remaining system. For AI features, start with one workflow in your existing business software.

A Working Product, with Clear Responsibility

Bill can be the primary technical partner for an agreed platform or own a defined application or backend alongside your CTO and internal team. Larger engagements use scoped stages, spending caps, and milestone reviews; a first assessment is a starting point, not the whole development engagement.

AI-assisted implementation is paired with hands-on review, manual testing and adjustment, and AI-assisted automated smoke tests. Agree the workflows that must pass before release, review the remaining risks, and scope ongoing support or further development explicitly.

What Should You Bring to the First Conversation?

Describe who uses the system, what needs to launch or work better, what already exists, and the important integrations. Share the target timing, budget context, and who can make product decisions. For an existing application, explain the failure or release blocker before sharing any confidential access details.

Need a mobile product too? See native iOS and Android development. If the product needs an AI feature, explore AI integration into existing systems. For the broader offering, see software development services.

What Needs to Launch or Work Better?

Bring the platform, the blocker, and the outcome your business needs.
