About me
I’m a full-stack developer with over 10 years of experience building backends, web, mobile apps and automation systems for clients across different industries. Right now most of my projects involve agentic AI development.
I build agents that automate real tasks inside your business, not demos or prototypes. I also have deep experience with web scraping, data extraction, and integrations that connect the systems you already use.
I deliver clean code and I’m always looking for the best way to solve a problem. Drop me a message with what you need.
