About Me

Engineering scale and reliability.

Michael Mensah - 1

I am a Senior Backend Engineer with 10+ years of experience designing and building robust, scalable, high performance systems. My core expertise spans Node.js, TypeScript, NestJS, and Golang, with deep experience in microservices, distributed systems, event driven architecture, and cloud native deployments on AWS and Azure.

I have shipped production systems across fintech, SaaS, blockchain/DeFi, and AI, including core financial infrastructure at Sterling Bank serving millions of users, multi-chain DeFi platforms, and AI integrated backends using LangChain, Claude, OpenAI, and Gemini.

Most recently I designed and launched a production MCP (Model Context Protocol) server, the health intelligence API you can explore on this site, covering server architecture, token-based authentication, tool and resource design, and integration with n8n, Flowise, and Claude Desktop. I am open to Senior/Staff Backend, Founding Engineer, and select leadership roles at remote friendly companies.
