## Work experience

Principal Engineer / Engineering Manager at Vista, Jun 2023 \- Present · 3 yrs 4 mos, Bangalore Urban, At Vista, I have led three cross\-functional engineering teams building digital marketing platforms for small business customers\. I owned platform strategy and execution, including the development of a centralized Placement Engine that enabled experimentation\-led delivery and scalable campaign execution\. Following this, I transitioned into a purely technical leadership role, leading the Digital Partnerships initiative at Vista\. In this role, I focused on building platform integrations and technical capabilities to enable more holistic, digitally focused marketing assistance for customers through partner\-driven solutions\. More recently, I led the design and development of an AI\-powered Customer Digital Advisor — a RAG\-based system built on a fine\-tuned Ollama model that autonomously analyses gaps in a customer's digital presence and generates and executes a tailored improvement plan\. I also built a PoC for domain\-specific LLM fine\-tuning, exploring embedding pipelines, vector stores, and model evaluation to assess production feasibility\.
