React and TypeScript web applications
Web applications where the React interface, API, data, access control, and operations form one maintainable system.

I build web applications where the interface cannot be separated from business rules, data, and operations: admin panels, internal workspaces, reports, APIs, and integration services. I typically use React and TypeScript on the client, Node.js on the server, and PostgreSQL or SQLite for storage. Astro remains my choice for content sites; products centred on long sessions, complex forms, and state need an application interface rather than a marketing page.
Work starts with the critical journey and data sources. Who creates an entity, who may change it, what happens when a request is repeated, and how does an operator see a failure? These answers shape the data model, API, and roles before a table library does. For an existing product, I first inspect dependencies, builds, migrations, and the release path. A rewrite is proposed only when its value can be demonstrated.
The scope is the software product: interface, backend, authentication, agreed integrations, tests for important paths, and run documentation. Market research, brand identity, and 24/7 support are not included by default. Acceptance is scenario-based: the right role can sign in and save data, unavailable services produce a useful error, and the team can start the project from its documentation.
If an established CRM, BI platform, or admin module covers the process, configuring it is more responsible than replacing it. Custom code makes sense for unusual workflows, permissions, integrations, or interfaces that materially affect daily work. For a public-facing site without a complex session, see marketing websites.
FAQ
Tap a question to expand the answer.
What stack do you typically use?
TypeScript across the stack: React or Astro for UI, Node.js for APIs, PostgreSQL or SQLite for persistence, plus REST integrations as needed.
How long does a typical project take?
Depends on scope. Focused tools often reach a usable MVP in 4–8 weeks with iterative vertical slices rather than a big-bang launch.
Do you write automated tests?
Yes where they pay off: critical user flows, API contracts, and data transforms—not blanket coverage for its own sake.
Can our team maintain the code after handoff?
That is the goal: explicit types, pragmatic architecture, short handoff notes, and optional pairing during transition.
What kinds of products do you build most often?
Admin panels, internal tools, dashboards, calculators, and content products where correctness and performance matter.
