David Inyang-Etoh

Senior Software Engineer and AI Engineer with 8+ years building production systems across the US, Europe, and Africa. I specialise in two things that are increasingly hard to find together: distributed backend systems that scale, and AI systems that actually work in production — not demos, not prototypes.

What I build:

On the AI side — multi-agent pipelines, RAG architectures, and agentic workflows using LangGraph, LangChain, and Claude. Systems with real evaluation harnesses, cost guardrails, and human-in-the-loop controls.

On the engineering side — cloud-native microservices on AWS, TypeScript and Python backends, event-driven systems, and team leadership. I've cut infrastructure costs by 66%, improved API performance by 35–47%, and shipped production systems across FinTech, SaaS, and Web3.

Projects I can talk to in depth:

• Vera AI — autonomous website conversion and support agent (LangGraph, Qdrant, RAG, multi-agent pipeline). Live on client sites.
• Cadence — relationship intelligence system for financial advisors. 5-agent LangGraph system with RAGAS-gated CI deployment.
• Meridian Connect — AI support chatbot with live MCP backend, cost controls, and LLM observability. Live on Vercel.

Background: - Collectwire (Team Lead, global payroll SaaS)  - Receeve GmbH (Senior SE, FinTech, Germany)  - Immutable X (Web3, Australia)  - 4 AI Engineering certifications (Ed Donner / Ligency, 72.5 hrs total).
