About Edet
AI Backend Engineer | Node.js, NestJS, LLM Automation, RAG Systems
Lagos, Nigeria - 5:22 pm local time
You're looking for someone who can build systems that stay reliable under real usage, integrate cleanly with the rest of your stack, and don't become operational liabilities six months later.
I build scalable backend infrastructure and AI-powered workflows for SaaS platforms, internal tools, and automation-heavy products.
Over the past 4+ years, I’ve helped teams:
✔ Reduce API latency by 50% using async processing, queues, and caching
✔ Cut production 5xx errors by 80% through service hardening and deployment improvements
✔ Maintain 99.9% uptime on live systems serving 2,000+ concurrent users
✔ Build RAG systems achieving 90% retrieval faithfulness
✔ Reduce manual operational workflows by 60% through internal AI systems
────────────────────────────
What I Build
► AI Systems & Internal Tools
LLM-integrated Slack bots, document processing pipelines, RAG systems, and AI agents that replace manual operations. Built with OpenAI, Gemini, or Claude — your choice.
► Scalable Backend Infrastructure
Production-grade APIs and distributed backend systems using Node.js, NestJS, TypeScript, Python, PostgreSQL, Redis, and BullMQ. Designed for scale, documented for handoff, and tested before delivery.
► Workflow Automation (n8n / Custom)
End-to-end automation pipelines connecting your tools Google Drive, Slack, Notion, CRMs, custom webhooks. I don't just drag and drop; I architect for reliability and error recovery.
► Cloud & Reliability Engineering
Docker, AWS, CI/CD pipelines, monitoring, logging, and infrastructure setups that keep deployments predictable and operational overhead low.
