What I bring to the table
AI Agent Automation
Turn any workflow into an AI agent. What takes 100 people can be done by 1. Research, outreach, reporting — fully automated.
02Websites That Convert
Not just pretty — built to drive leads and sales. Full GA4 + GTM tracking, zero 3rd-party cost. Every click measured.
03Custom Web Apps
Dashboards, portals, automations, integrations. If you can describe it, I can build it. Fixed price, fixed date.
04Google Ads + Landing Pages
High-converting pages built for paid traffic. Conversion tracking baked in from day one. ROI you can actually measure.
05Infrastructure & Security
Architecting fast, secure systems built for scale. Multi-point security audits. No chances left for attackers.
06Speed & Performance
Slow sites lose money. Deep inspection, systematic optimization. Sub-second loads that Google rewards.
