What I'm looking for

I seek roles building production AI products and scalable full-stack systems, in collaborative teams with growth and impact focus.

I am a software engineer with 4+ years of experience building scalable back-end and front-end systems and developing AI agents. I deliver high-quality solutions across diverse projects and have contributed to production AI products and mobile applications.

My work includes designing APIs, background workers, and customer-facing features; implementing cloud infrastructure and CI/CD; and creating conversational AI experiences that improved response times and user satisfaction. I have experience with AWS, PostgreSQL, MongoDB, REST APIs, and modern JavaScript frameworks.

I collaborate effectively in remote and hybrid teams, focusing on practical, impact-driven engineering — from no/low-code AI platforms and chat apps to commerce and blockchain-backed inventory systems.
