AI Systems Engineer
Background
I’m a full-stack engineer with over 10 years of experience, having delivered 500+ client projects delivered with consistent 4.9★ feedback across global marketplaces.
My background comes from building production systems for businesses — including web platforms, internal tools, and automation workflows — working directly with clients across 50+ countries.
Today, I specialize in AI systems and RAG architecture, building assistants trained on your business data, integrated into real workflows, and deployed on your own infrastructure.
Technically, I work across Next.js, Laravel APIs, and Python-based AI systems, with the flexibility to integrate OpenAI, Gemini, or local models depending on your needs.
My approach is simple: understand your business first, then engineer the right system. No demos, no shortcuts — only systems you can rely on.
