I build automation systems that eliminate the manual work
running in the background of most businesses.
After 15+ years on PHP and Python backends, I specialize
in one thing: connecting the tools you already use and
removing the human steps in between. Document processing,
invoice verification, ERP integrations, local AI systems
that keep your data inside your company.
I work directly with business owners and technical managers.
No handoffs, no junior developers, no surprises on scope.
If your team does something manually every week that a
machine should be doing - send me a message
