Senior Full Stack Engineer / Solution Architect
Raymund F. Cuizon builds
backend systems that
outlast the roadmap.
10+ years designing and shipping scalable web applications, enterprise systems, SaaS platforms, and cloud-native solutions — for startups, global companies, and enterprise organizations including Accenture, Moustache Republic, and GSS Lab. Backend specialist with NestJS and Node.js at the core, Next.js and React on top, and lately, AI-assisted development and LLM-powered features woven through all of it.
// about
Full stack, backend-first.
I specialize in backend systems and modern web technologies — designing scalable REST APIs, architecting distributed systems, building SaaS platforms, integrating external services, and writing software that's still maintainable long after the business has grown past its first version.
Recently I've expanded into AI-powered software: integrating LLMs, vector embeddings, and semantic search, and working AI-assisted development tools like Claude Code, Cursor, and GitHub Copilot into my daily workflow. I like taking a product from a rough idea to something in production, without losing clean architecture or code quality along the way.
