The Good Trends

Client Context & Objectives

The Good Trends is a mission-driven US marketplace connecting wholesale healthy food producers and independent local grocers. The objective was to reinvent wholesale food purchasing by removing cumbersome distributor markups and giving grocers transparent ordering.

The Core Technical Challenge

The business needed to go from concept to a production-ready marketplace that could handle multi-tenant store onboarding, live POS inventory synchronization, real-time volume discounts, and investor diligence on a fast timeline.

My Role & Architectural Approach

Role: Lead Architect & Full-Stack Engineer. Responsible for end-to-end platform design, database schema, REST APIs, frontend portal, third-party integrations, and cloud infrastructure.

Architected a modular Django and React application backed by PostgreSQL and AWS. Implemented an event-driven pricing engine capable of evaluating complex tier discounts and bundles in real-time under high concurrency (1,000+ events/sec). Built automated CSV ingestion and POS integrations so store owners could sync catalog items seamlessly.

• Designed self-serve onboarding portals for brand registration, automated monthly invoicing, and low-inventory alerts.
• Deployed containerized architecture on AWS with auto-scaling to absorb unpredictable promotional traffic spikes.
