Jobshack is a material trading marketplace connecting sellers of construction materials (soil, rock, aggregates) with buyers. It offers an intuitive interface for creating listings, negotiating offers via real-time chat, processing payments, and managing transactions—streamlining procurement for both parties.

Jobshack required a robust digital marketplace capable of handling complex material trading scenarios including bulk quantity negotiations, location-based material discovery, and secure payment processing. The challenge was to facilitate real-time offer negotiations between buyers and sellers, manage multiple transaction statuses from offer acceptance through delivery finalization, handle automated seller payouts via Stripe Connect, and provide intelligent content moderation all while maintaining an intuitive user experience for both administrators and marketplace participants.
We developed a full-stack material marketplace ecosystem that combines powerful listing management with intelligent offer negotiation and secure payment processing.
Implemented a comprehensive listing engine supporting multiple categories (Sale, Removal, Import), material types (Rock, Soil, Other), quantity-based pricing, geo-location with Google Maps integration, certification uploads, and automatic listing expiration notifications.
Built a dynamic chat-based negotiation system with offer creation, counter-offers, acceptance/decline flows, and real-time messaging powered by Pusher WebSockets enabling instant communication between buyers and sellers.
Integrated Stripe Checkout for secure buyer payments with automatic tax calculation, and Stripe Connect for seller payouts with connected account management, transfer scheduling, and payout history tracking.
Created automated message filtering with profanity detection, URL blocking, and phone number masking to maintain platform integrity and prevent off-platform transactions.
Implemented geospatial search using MongoDB 2dsphere indexing with Google Places Autocomplete, enabling buyers to discover materials within proximity of their project sites.
Built intelligent notification workflows including new offer alerts, payment confirmations, listing expiration warnings, pickup reminders, and off-platform email notifications via SendGrid.
The Jobshack platform delivered a powerful and user-friendly material marketplace solution. Material suppliers gained complete control over their listings and sales, while buyers enjoyed a frictionless procurement experience with real-time negotiation capabilities.
