Custom tools, quoted at a fixed price.
Remote work. Tell me what you need — I reply within 2 business days with a quote. No calls unless you want one. I do not take live-casino or gaming work.
Custom single-file offline HTML tools
Small, self-contained tools that open in a browser, work offline, and stay yours. Built to replace a messy workaround, not to add a platform.
Already in this family: Invoice Studio, an OrgChart tool, an image resizer, and The Marriage Ledger. The first three are named here as proof; they do not have public links yet.
Spreadsheet-to-app upgrades
When an Excel or VBA workbook, a Power Platform app, or a sheet that grew by accident is doing too much — I turn it into something a team can actually use. AI-assisted where it helps, not as a gimmick.
Operations and staffing dashboards
Rota coverage, KPIs, QC trackers and bonus calculators for shift-based teams in hospitality, contact centres, venues and retail.
Small AI-assisted builds
Landing pages, simple sites and automations — scoped tightly, delivered as a finished piece of work, quoted up front.
03 — How I work
Private, one-time, and built to be used.
Private and local-first
Work stays on the device wherever that is possible. No obligatory account, and no tracking as a default.
Yours to keep
One-time pricing. No subscription as the default. You receive a tool you can keep using, not a seat you have to renew.
Built to be used
Small, practical interfaces — not a long implementation a team will quietly abandon.
A simple path: you describe the job, I send a fixed-price quote, we agree the scope, and you receive the tool.
04 — About
Dan Dinchev, based in Sofia.
Dinchevian is my studio. I build small, practical software — often a single HTML file you can keep, open offline, and run without an account or a subscription. I also take on custom work for small teams that want a clearer tool than a spreadsheet, without a long implementation project.
