At ABV Zimbabwe, I connected point-of-sale, inventory, invoicing, and sales-reporting systems for ABV Boards and ABV Hardwares, turning manual operations into automated workflows with the owners.

I integrated the ZIMRA Fiscalisation Data Management System API into the invoicing system, covering device registration, certificate configuration, fiscal invoice submission, and QR-code generation. I also built a cutting-list calculation algorithm to replace manual estimating and shipped AI features into live products.

At Progress Group of Schools, I designed and shipped school management software for student records, fee invoicing, payment tracking, procurement, and parent communication. I built receipt/OCR and payment-matching agents for finance operations and created a bank payment integration pathway.

As an independent software developer, I’ve delivered 44 production applications for businesses and schools using React, TypeScript, Node.js, Supabase, and PostgreSQL. My work includes multi-tenant POS, inventory and finance systems, automated sales-sheet processing, and school timetable generation.
