At CiiRUS, I designed, deployed, and operated 50+ production n8n workflows connecting social platforms and marketing data with Supabase. These automations supported social publishing and daily data syncs for two brands.

I also built a multi-account Marketing Dashboard with React and Supabase/PostgreSQL, bringing paid campaign and website performance data into one view with AI usage and cost. A content-calendar app I built automated publishing to four social networks and removed 10 hours a week of manual posting.

At GFT Technologies, I developed and maintained more than 400 automated Web and API tests in Java with Selenium WebDriver and Cucumber for a top-tier bank. The work raised regression coverage from 60% to 80%, while Jenkins pipelines cut regression cycle time from 16 hours to two.

Earlier, at SIS Innov & Tech, I created and maintained automated test suites for a bank, and at Digisystem I tested a fintech product and introduced Selenium automation for critical user flows. My background spans AI and process automation, QA automation, and CI/CD, and I’m available for remote roles in US and EU time zones.
