At Geeks of Kolachi, I build client-facing web products with React.js, Next.js, and backend REST APIs. I contributed to a secure, multi-tenant, fully on-premises SaaS platform with tenant and company-level isolation, subscription-based licensing, and Super Admin controls.

I shipped OctaPOS, a retail POS and ERP platform with real-time inventory tracking, multi-currency payments and settlements, offline syncing, and multi-terminal support.

I also architected Stratagem IMS, a Shopify-native supply-chain SaaS with supplier portals, purchase-order automation, and inventory dashboards. Its featured project includes real-time two-way product and order sync, BOM management, and an AI demand-forecasting UI.

Earlier, at Al-Rahim Textile Industries Ltd., I built a supplier evaluation web module and companion mobile app, along with a Flutter data management app with CRUD operations, filtering, and PDF export. I also deployed the full application using a local machine as a public-facing server.
