Saharanpur, UP, India4y exp

“Performance marketer focused on e-commerce growth, managing $60K–$80K/month budgets primarily on Google Ads with supporting Meta. Demonstrated disciplined testing and volatility control, improving ROAS from 3.8 to 5+ in ~3 months while scaling spend ~30% and keeping revenue stable. Strong in full-funnel cross-platform allocation (Google/Meta/TikTok) and systematic troubleshooting of performance declines.”

“Hands-on paid media specialist focused on Meta and Google Ads for lead generation, especially across B2B and service-based businesses. They emphasize full-funnel ownership—from strategy and setup through testing, optimization, reporting, and client communication—and show a strong bias toward improving lead quality and efficiency rather than chasing volume alone.”

“Built and shipped a production "Campaign AI" multi-agent system (LangGraph) that personalizes B2B outbound emails at scale using Apollo.io prospect data, clustering-based segmentation, and 21 persona variants. Notably uncovered that high click rates were largely email security scanners and created a validated bot-detection/scoring pipeline (timestamps/IP/user-agent/click patterns), bringing reported engagement down from ~40% to a trusted 5–8% that aligned with real conversions.”

“Data/AI practitioner who built a production LLM-driven healthcare claims analytics and dashboarding system to reduce avoidable ER visits—processing 1.4M+ claims, flagging 19% as non-emergent, and projecting ~$2.8M in annual savings. Demonstrates strong real-world LLM reliability and performance engineering (grounding, numeric validation, caching, materialized views, quantization) plus orchestration experience with Airflow and Azure Data Factory.”

“Built and scaled an internal AI code-search/assistant agent that expanded from engineering-only to broader internal users, tackling legacy code and inconsistent standards to make a RAG pipeline production-ready. Uses a metrics-driven approach (user feedback + automated Python evaluation for retrieval relevance and latency) and has handled high-pressure outages, including moving parts of the stack off AWS and adopting Milvus on internal infrastructure for resilience.”
