Portimão, Portugal • EU Work Authorization Available

PROFESSIONAL SUMMARY
We're living through an era of rapid change, and I'm excited to be part of building what's next. AI Agent Developer & Automation Architect with 10+ years progressive experience in digital business (CBDO,
affiliate R&D, performance marketing) and 3+ years deeply focused on intelligent automation and autonomous AI systems. I'm a results-driven entrepreneur and problem solver, not a traditional coder—
leveraging advanced architectural patterns to engineer production-ready solutions. Successfully generated $100K+ monthly revenue through automated workflows, scaled programs to $3M+ across multiple
markets. Expert in orchestrated agent workflows, RAG Systems, Vector Databases & Embeddings.
Thanks to progressive LLM models, I now have bandwidth to explore interesting challenges in R&D departments—seeking solutions for key tasks, studying trending tools/services to increase revenue and hit
KPIs. Managed 3-person dev team, trained specialists on Flowise/ClickUp automation, built content factory for AI education. Own MVP/SaaS projects in development, open to discussing investment
opportunities for scaling ideas. Immediate availability: 20-30h/week in Portugal (Portimao office, can host 2-3 team). Service Agreement ready (Base + 35% tax). Given my current English proficiency, I prefer
structured task intake via project management systems—Jira, Confluence, Linear, ClickUp, Notion, HubSpot, Salesforce) enabling clear written communication through tickets and documentation. This
summary provides key highlights; detailed experience, case studies (non-NDA), and project examples are available on my GitHub repository.
