Business systems,built across web,desktop.
Eight years building and maintaining systems that run real operations — across enterprise ERP, SaaS, CRM, booking, integrations, desktop and mobile software.
My recent work includes a custom sourcing CRM, booking and practice-management software, a property maintenance platform, an internal ERP, an Odoo commerce system and specialist Windows applications. I have delivered as a solo developer, backend owner and project lead across Node.js, React, .NET and Python stacks.
Earlier, I maintained a plantation ERP and three connected desktop applications handling attendance, field activity, payroll, cooperative deliveries, transport quotas and reporting across multiple estates. That work demanded careful investigation of high-volume operational data and incorrect salary calculations.
