Process
OSIH builds backend and geospatial systems around operational reality: incomplete records, unreliable addresses, uneven connectivity, multilingual users, informal commerce, and rapid regional change. The work begins with the constraint, not a preferred stack.
We work where product requirements become architecture problems: high-throughput APIs, low-latency matching, multi-country platforms, location-aware operations, fragmented data, and backend systems that must stay understandable as they grow.
Our strongest proof comes from Africa. The engineering experience behind OSIH includes Cameroon's first digital address system, with 22,000 live indexed localities designed for a country of 27 million people; proprietary geohashing and location APIs; Mobile Money payment gateways; SMS infrastructure; and platforms designed for slow connections and small screens.
OSIH is led by more than 15 years of engineering and technical leadership across Africa, Switzerland, Germany, Spain, and the United States. The work spans full-stack delivery, software architecture, cloud deployment, DevOps, product strategy, location-based advertising, and leadership of teams up to 12 people across concurrent products.
English, French, Swiss German, German, and Spanish capability supports work across markets without treating language and culture as a late localization task.
Each engagement has direct senior ownership. Business constraints, product behavior, data design, and deployment architecture are handled as one system rather than passed between disconnected teams.
We begin with working software early enough to test the architecture against reality. Shared components are designed deliberately: Bwendi demonstrates how one strong location layer can support valuation, marketplaces, consumer matching, and future operational systems without forcing each product to solve geography again.
African institutions and operators facing addressing, logistics, payment, data, or trust gaps. Swiss hospitality and regional brands seeking direct digital demand. Agencies and scale-ups that can build the interface but need senior ownership of the system underneath it.
