What I'm looking for

I’m looking to build scalable SaaS and production AI automation—owning architecture, performance, and CI/CD—so systems stay reliable in real-world use. I want to lead technical decisions and ship intelligent features with RAG/LLMs.

I’m a Senior Full Stack Engineer with 7+ years building scalable SaaS and enterprise systems using Laravel, React.js, and AWS. I’ve improved performance by 40% and helped deliver production-ready solutions for global clients.

I also design and build AI-powered applications using RAG, LLM integration, and workflow automation—ranging from chatbots to AI-driven CRM systems using vector databases and local LLMs (Ollama). As a Solutions Architect/Technical Lead, I drive architecture, scalability, and CI/CD, including managing deployments with 99.9% uptime.
