Good fits
Quote calculators, expense trackers, pricing tools, simple inventories, project budgets, intake forms and offline dashboards.
A small offline tool built around your workflow.
When a spreadsheet is no longer enough, I can turn one focused process into a clear HTML and JavaScript calculator, tracker or dashboard. It opens in a browser and can work without a server, subscription or user account.
What you receive
A ready-to-open ZIP, a clean interface, brief usage notes and source files. The scope is agreed before development begins.
Local-first by default
For offline tools, working data stays in the browser. No external account, database or connected bank is added unless the agreed scope requires it.
Starting scope
A personalized quote template starts at US$39. Small, focused offline tools start at US$79 and include up to two rounds of adjustments within the agreed scope. Larger integrations are quoted separately.
Describe the problem and request a quote
