Designing high-scale conversational systems & cross-platform super apps.
I am a systems co-founder and software engineer coding highly performant products. Operating between Addis Ababa and international startup channels, I engineer core platforms including **EthioVoice AI** (multilingual conversational banking voice agent) and **Black Diamond** (cross-platform enterprise mobile super-app).
Focusing on **Rust**, **Go**, and **C**, I build optimized speech translation loops, offline state caches, and secure banking transaction pipelines.

Bank FAQ Knowledge
Natural Voice Response
Engineering Highlights
- Software-Only Pipeline: Operates entirely over standard HTTPS/WebSockets SDKs, bypassing carrier phone lines and PBX systems.
- The Translation Sandwich: Transcribes local acoustic languages, translates to English for logic and tool calls, and replies in premium local audio.
- RAG Policy Validation: Maps questions to local vector indexes in ChromaDB, preventing hallucinations on banking policies.
EAS Production Build
Offline-First State
Reliable DB Nodes
Engineering Highlights
- Offline-First State Sync: Manages local SQLite memory on mobile, resolving synchronisation conflicts on connection.
- Expo EAS Build Pipelines: Integrated CI/CD workflows producing lightweight, optimized Android & iOS builds.
- GraphQL Gateway: Decouples and maps deep transactional endpoints efficiently, reducing network traffic.
