An escrow marketplace backend for small merchants in Ethiopia. Buyers pay with Telebirr, CBE Birr or card through Chapa, and the money is held until they confirm delivery. Every birr goes through a Blnk double-entry ledger, with settlement, refunds and payouts as retryable background jobs and a daily reconciliation against Postgres.

An offline-first logistics tracking and proof-of-delivery platform for the Ethiopian trucking market. A Go backend serves a Next.js dispatcher dashboard and a customer tracking portal, while a React Native driver app keeps working without signal, then syncs and resolves conflicts when it reconnects.

An online store for an Ethiopian pajama and loungewear brand whose customers shop from their phones in Addis Ababa. A custom WooCommerce theme with no page builder and no plugins beyond WooCommerce, a pay-on-delivery checkout where the phone number is the account and a map pin stands in for a street address, and new orders posted to the staff’s Telegram group with buttons that move them along.

The backend of a proof-of-delivery system for the Ethiopian Pharmaceutical Supply Service (EPSS). We split it into three microservices: Core for the business logic, Auth for authentication and authorization, and an async messaging service built on Kafka, all deployed on AWS. We worked with an intermediary company and a technical consultant to keep the integration aligned with what stakeholders needed.

A command-line RSS aggregator in Go. Each user follows their own feeds, a long-running aggregator pulls new posts into PostgreSQL on a timer, and you browse them from the terminal. The database layer is generated with sqlc, with goose for migrations.
