Led engineering for B2B e-commerce infrastructure serving 8 African countries — from catalog and delivery routing to the technical due diligence for the Wasoko–MaxAB merger.
Designed and delivered a catalog service supporting products, pricing, taxes, and recommendations for 10K+ SKUs across 8 African countries with an integrated promotion engine.
Product catalog was slow, inconsistent across countries, and lacked promotion capabilities — directly impacting order volume and merchant experience.
Built a unified catalog with per-country pricing, tax rules, and recommendations. Integrated a promotion engine that applied discounts, bundles, and tiered pricing dynamically.
Reduced request latency by 60% and increased order volume by 14% through the integrated promotion engine.
Architected an optimized routing service using GraphHopper, computing optimal delivery paths based on customer locations, vehicle capacity, order volume, and product dimensions.
Delivery routes were manually planned, leading to high fuel costs, long trip times, and inefficient return-order handling across African cities with poor road data.
GraphHopper-based routing with vehicle capacity constraints, order volume optimization, and batching of nearby return orders with active deliveries.
Reduced fuel costs by 30%, trip duration by 23%, and minimized return trips through intelligent batching.
Designed a location service to accurately map delivery points in regions lacking reliable routing data, using delivery partner GPS coordinates at each drop-off.
Many African regions lack reliable address systems and routing data, causing failed deliveries and high customer support volume.
Captured GPS coordinates at each delivery drop-off with support for location images and notes, building a proprietary delivery point database over time.
70% reduction in customer support calls within one quarter and 8% decrease in overall trip time.
