This dual specialization allows me to bridge the gap between complex business workflows and production-ready Agentic AI solutions. I specialize in architecting self-evolving agentic systems that transform data-heavy, manual processes into autonomous, high-impact workflows. By combining my domain expertise in digital advertising with advanced AI engineering, I build solutions that are not just technically sophisticated, but fundamentally aligned with ROI and business growth. ✔️ Agentic Architectures: Designing hierarchical multi-agent systems and specialized sub-agents. Expert in implementing Recursive reasoning loops, Self-correction, and secure tool execution via MCP within isolated Sandboxes. ✔️ RAG & Memory Systems: Engineering advanced Retrieval-Augmented Generation with multi-tier memory (Short/Long-term, Caching) to maintain persistent state in complex, multi-turn environments. ✔️ Observability & Reliability: Implementing Evaluation Harnesses (LLM-as-a-judge) and deep observability pipelines to ensure systems are secure, cost-optimized, and production-grade. ✔️ AI-Augmented Development: Delivering end-to-end products using TypeScript (Next.js), Python, and GCP/Docker. I focus on architectural integrity and rapid delivery through AI-native workflows. Performance Marketing Track Record: ✔️ Managed $100,000+ monthly spend across Google, Meta, and LinkedIn for B2B/SaaS and E-commerce. • Global campaign deployment in 7 languages; specialized in GTM, GTM, and GA4 integration. ✔️ Former agency veteran and e-commerce owner
