Web applications built around your workflow
I build custom web applications with React, Next.js, and Node.js — from the interface and data model through to integrations and release. We start with the workflow your team needs to get right.
Focused engagements from $500. Larger work is scoped in milestones.
Relevant work
A complete web presence and lightweight operations console for solo dental practices: marketing site, patient portal, AI booking assistant, and admin console, packaged as a sellable product.
Solo full-stack design and development

Read the case studyWhere I can help
- You have a working concept, product specification, or existing workflow that needs to become software.
- Your current application has become slow to change because the interface and data flow are inconsistent.
- You need one developer who can own a feature across the front end, API, database, and deployment.
- Your team needs help shipping a focused product milestone without adding a permanent hire.
What’s included
- Product and technical scoping before code starts
- Responsive React or Next.js interfaces
- Node.js APIs, authentication, and third-party integrations
- PostgreSQL, MongoDB, or Convex data modeling
- Role-based dashboards and operational workflows
- Testing, deployment support, and a clear handoff
The useful part starts before the first component
A custom web application can fail while every screen still looks polished. The usual cause is a weak model of the underlying work: permissions are added late, status changes have no clear owner, or the data model fights the reporting the business needs.
I start with the workflow. Who is doing what? Which state changes matter? What must be auditable? Once those answers are clear, the interface and backend have something solid to follow. That is especially important for admin products, multi-role platforms, booking systems, and software that replaces spreadsheets.
A full-stack build without the handoff gaps
My work spans the product surface rather than stopping at a set of screens. I can build the React or Next.js front end, connect it to an existing API, or take responsibility for the Node.js service and database as well. When a project includes another specialist, I document the boundaries and keep integration work visible.
The stack is chosen around the product. Next.js is useful when the application and public website live together. A separate React app can be a better fit for an operations-heavy dashboard. PostgreSQL works well for strongly related business records, while MongoDB or Convex can make sense for different access patterns. I will explain the choice in ordinary language before it becomes expensive to change.
Engagement and budget
Focused fixes and small product milestones can begin at $500. Most custom application work is scoped as a sequence of milestones, with a price and acceptance criteria attached to each one. Larger builds are estimated after a short discovery conversation and a review of the requirements.
If the scope is still loose, send what you have. A rough brief, an existing site, screenshots, or a list of problems is enough to start a useful conversation.
How we’ll work
Scope
We identify the users, the business-critical workflow, existing constraints, and the smallest useful release.
Build
I work in visible milestones. You review working software regularly instead of waiting for a large final reveal.
Release
Before handoff, I cover failure states, responsive behavior, deployment, and the parts another developer will need to maintain.
Before we start
What does custom web application development include?
It can include scoping, interface development, APIs, authentication, database design, integrations, testing, and deployment. The project brief is used to decide which parts belong in your engagement.
Can you work with an existing application?
Yes. I can add a feature, rebuild a difficult area, connect a new service, or help untangle a React, Next.js, or Node.js codebase before further development.
How long does a web application take to build?
A focused milestone may take one to three weeks. A larger application is planned in stages. I give each stage a concrete deliverable instead of offering a single vague completion date.
Will I own the code?
Yes, unless we agree otherwise for a specific licensed dependency. Your project, source code, and credentials remain yours.
