I develop and maintain the B2B sales force web platform (React 19 + Vite) for a European wholesale distributor, working within a distributed engineering team (mobile, backend, and web). • Built a modular frontend featuring a product catalog, order management, shopping cart, customer and prospect management, sales visits, geolocation-based routing, a form builder, and shipment tracking. • Integrated the platform with over 50 REST APIs (Django backend, SAP ERP) and external services—such as SalesLayer (PIM), Google Maps, and Excel import/export—supporting multi-language capabilities and real-time synchronization. • Led the migration from the native mobile sales app to the responsive web platform. • Work asynchronously using Scrum, including code reviews and testing (Vitest, Testing Library, MSW).

Creator and operator of Ventify — multi-tenant POS + inventory SaaS in production for 3 businesses (flagship: 4 branches, 8 POS, 8000+ products, ~600 sales/day, $80k+/month, +97% sales). Built with Next.js 14, React 19, TypeScript, Firebase, RBAC and real-time sync. Created Venty, an autonomous AI business agent (Firebase Genkit, Gemini/DeepSeek, RAG) that answers analytics queries and executes actions inside the POS — experience directly transferable to locally hosted AI models and coding-agent workflows.
