AI/ML Engineer

Professional Summary

AI/ML Engineer who ships production GenAI systems - RAG pipelines, multi-agent LLM applications, and applied NLP for low-resource Amharic and Afaan Oromo - on a strong MLOps and data-engineering foundation (Feast feature stores, model serving, and pipelines on AWS/Kubernetes). Builds end to end: retrieval and embeddings, LLM serving, and low-latency inference APIs. Open-source author and independent NLP researcher in Ethiopian-language AI.

Experience

Senior Data Engineer

Kifiya Financial Technology PLC

Jul 2026 - Present
Addis Ababa, Ethiopia
  • Built an enterprise multi-agent RAG document assistant - LangChain + CrewAI over Llama 3.3 70B (Groq), ChromaDB hybrid retrieval with cross-encoder reranking, Keycloak SSO, and PostgreSQL conversation memory
  • Built the end-to-end credit-scoring ML pipeline - Feast feature store (S3 registry, Redis online, Aurora offline) with automated feature-refresh across batch domains; FastAPI inference on EKS with <200ms p95 latency
  • Built an AI data-standardization agent using a provider-agnostic LLM layer (OpenAI / Ollama / HuggingFace), containerized and deployed on AWS
  • Developed a FastAPI embedding service for Ethiopian-language retrieval (EthioLLM; Amharic/Ge'ez/Afaan Oromo/Tigrinya/Somali) with batch processing and a fallback model

Data Engineer

Kifiya Financial Technology PLC

Oct 2024 - Jun 2026
Addis Ababa, Ethiopia
  • Built the organization's first AWS-managed lakehouse (Athena + Glue Data Catalog) orchestrated with Mage AI - 6-hour micro-batch ingestion for institutional partners, 300+ tables / 7,000+ columns, high-watermark extraction, and date partitioning
  • Designed a lightweight real-time CDC pipeline under compute constraints - OLake for MySQL binlog to Apache Iceberg (Polaris catalog), queryable via Trino
  • Built and deployed the Batch API microservice (FastAPI + EKS) ingesting domain payloads from partner institutions; persists to MongoDB and pushes features to Feast (Redis) for credit-scoring consumption
  • Built production Firebase Analytics export pipelines - BigQuery to S3 Bronze Parquet to Iceberg Silver via PyIceberg, with partner-isolated Airflow DAGs and Secrets Manager + IRSA
Reduced pipeline failures ~60% by migrating Mage AI to Airflow on EKSAchieved 99.9% pipeline reliability across production data workflowsReduced data processing costs by 40% through optimization

Software Developer

HST Consulting PLC

Nov 2023 - Oct 2024
