Built Ompere, an instant price-calculator and resale platform for diesel generators and industrial machinery, with a Next.js frontend and a Laravel backend API. Sellers use the built-in price calculator to check their equipment’s value online in seconds, then get contacted by the platform to complete the sale. An owner selects their generator’s brand, capacity (KVA), and year in the calculator to instantly see an estimated market price — no phone calls, no waiting for a dealer quote. Once they submit, the Ompere team reaches out to inspect the machine, confirm the offer, and arrange pickup and payment. The platform also supports well-known industrial brands including Tata Motors Gensets, Volvo Penta, Ashok Leyland, CAT, Crompton Greaves, and Perkins, and connects sellers with a verified buyer network across India.
