Hi, I'm AC Jacinto
Senior Full-Stack Web Developer
My specialization
Web platforms & internal systems
Business systems shaped around how your team works: the right access for each role, admin tools, dashboards and reports.
Linux servers, deployment & security
I set up and look after the servers your platform runs on: launches, monitoring and security, from HTTPS to locked-down access.
Integrations & automation
I connect your platform to the tools around it: online payments, automatic emails, AI features, PDF and Excel reports, live updates and scheduled tasks.
