About

Engineering systems that scale

I'm Jeroham Sanchez — a Senior Fullstack Systems Engineer with 8+ years of experience building production-grade web applications, APIs, and AI-powered systems for startups and enterprises.

My specialty is the intersection of modern web engineering and AI — designing systems that use language models effectively, not just as a gimmick, but as a genuine multiplier for user value.

I work in short, high-quality iteration cycles. You get clean code, solid documentation, and a system you can actually maintain and extend without me.

Full-cycle development: architecture → deploy → monitor

AI integration specialist: LLMs, RAG, agentic workflows

Security-first mindset with OWASP practices

Async-first, remote collaboration expert

Performance obsessed: Core Web Vitals, DB optimization

Clear technical communication with non-technical stakeholders
