Grant Emeke Oseji

Core Profile

Artificial Intelligence & Backend Systems Engineer focused on operationalizing agentic execution loops, dense vector retrieval (RAG), and fault-tolerant microservices supporting low-latency transaction and ingestion pipelines.

• 🎓 Education: Pursuing B.Sc. in Computer Science at MIVA Open University (Expected July 2027)
• 📍 Location: Asaba, Delta State, Nigeria
• ⚡ Specialties: Agentic Reasoning Engines, Context Engineering, Distributed Event Pipelines, & Cache Strategies

Core Architectural Competencies

• 🤖 Agentic Reasoning & Tool Orchestration: Designing structured execution loops with dynamic multi-tool routing, deterministic validation schemas, and context boundaries.
• 🧠 Semantic Vector Retrieval (RAG): Structuring chunking strategies, dense embedding pipelines, and vector indexing using ChromaDB to mitigate domain-specific hallucinations.
• ⚡ Event Streaming & Message Queues: Decoupling microservice state machines and analytical ingestion pipelines via Kafka and RabbitMQ event buses.
• 🗄️ High-Performance Caching & Data Integrity: Implementing asynchronous multi-tier Redis caching with dynamic TTL invalidation and strict database normalization.
