About this gig

Replace one manual spreadsheet workflow with a focused custom business web app. I build database-backed tools using Next.js, TypeScript and PostgreSQL, with Python APIs when appropriate.


Starter scope: one workflow, one user role, managed sign-in, one record type with up to eight fields, create/read/update/delete actions, searchable table and CSV export. Includes up to three screens, responsive design, source code, database setup instructions, a handover guide and two revisions. Delivery: 14 days.


Message me before ordering. We agree fields, access rules and acceptance criteria first. My ICARUS Command Center is an independent portfolio project with fictional demo data, not a paid client engagement.


Multi-role systems, payments, ERP migration, complex integrations, real-time tracking and mobile apps require a separate quote. Paid hosting, domains and ongoing maintenance are excluded.

I build responsive business websites, landing pages and scoped internal tools under my independent brand, ICARUS. My portfolio includes an interactive business website and a local operations tool using Next.js, FastAPI and PostgreSQL, with fictional demo data. I also work with Python, SQL and n8n for reports and workflows. I agree on screens, content and acceptance checks, then implement, test and document delivery. My samples are independent projects, not paid client results. Native Spanish and C1 English.
