Professional Experience
Afridev⁠, Full-Stack Engineer
10/2025 – 03/2026
  • •Wisse Media AI⁠: Architected a distributed media engine using Django and Vertex/​OpenAI. Decoupled heavy tasks (Video/​Audio synthesis) into asynchronous Docker workers, ensuring 100% sync-service uptime. Developed proprietary Python logic for library-free EPUB/​PDF generation reducing dependency overhead and improving generation performance.
  • •Bar Assistant:⁠ Engineered a state-aware Learning Management System with a robust persistence layer, allowing AI-driven quiz generation and data ingestion to resume instantly from interruptions or refreshes.
  • •Infrastructure: Managed containerized deployments on Hostinger and Contabo VPS via custom CI/​CD pipelines for "push-to-deploy" automation.
    • Eskalate⁠, Mobile Development Team Lead
    07/2025 – 09/2025 | Nazareth, Ethiopia
  • •RemedyMate: Led a team of 4 to deliver a production-ready AI health platform using Flutter and Golang/​Gin.
  • •RAG Engineering: Designed a safety-first RAG system using Gemini API, implementing context-filtering that reduced AI hallucinations/​misguidance by 90%.
  • •Optimization: Reduced latency by 50% via offline-first architecture and increased deployment frequency by 30% through automated testing pipelines.
    • Projects
  • •Built a scalable backend with 100+ unit tests, reducing bug incidence by 45%. Implemented end-to-end security using JWT for session management and Bcrypt for password encryption, enforcing 20MB file-upload limits and secure data persistence.
  • •Engineered a pipeline with PostgreSQL, dbt, and Dagster. Integrated YOLOv8 for image enrichment; exposed via FastAPI.
  • •Built interpretable credit scoring models aligned with Basel II compliance using MLflow and FastAPI.
