Vishnu Kumawat's Work | ContraWork by Vishnu KumawatVishnu Kumawat
AI Engineer & Full Stack Developer building smart solutions.
I built a B2B bulk purchasing and e-commerce platform that connects buyers and sellers through one centralized digital marketplace. It was designed with separate dashboards for buyers, sellers, and administrators. It includes product listings, three-level categories, live bidding, product approvals, inventory tracking, cart and checkout, Razorpay payments, order management, reports, and analytics. Buyers can find products, compare suppliers, submit bulk requirements, place orders, and join live bidding. Sellers can manage products, inventory, inquiries, orders, and sales from their dashboard. The platform also helps the business team manage buyers, sellers, leads, approvals, orders, and supplier activity from one system. I developed a complete project management and team collaboration SaaS with frontend, backend, REST APIs and a structured database. Our work covered secure login, file management, real-time updates, search, role-based access and responsive screens. Key modules included workspaces, projects, sprints, tasks, Kanban boards, team discussions, notifications and reports. We then integrated the OpenAI API to power six AI features: AI sprint planning and milestone breakdown, automatic flowchart design, automated deadlines, smart reminders, AI task assignment and skill-based team building. I developed a complete English learning platform with AI support, including the frontend, backend, database, APIs, user login, payment setup, communication tools, and reporting sections. The work also covered speaking and writing evaluation, interactive graphics, 3D learning elements, role-based access, responsive layouts, PWA support, CRM integration, security, speed improvements, and live server setup. I built the ERP with separate sections for operations, accounts, fleet records and employee access. It includes GR booking, trip planning, Challan generation, shipment tracking, Proof of Delivery, customer ledger, payments, vendor expenses, internal chat and audit records. The system also controls status changes, document creation, financial entries and branch access. This helps employees manage their work without relying on different registers and files.
