What I'm looking for

I seek a Data Science role applying advanced ML/AI and data engineering in a collaborative, impact-focused team that values production-ready solutions and growth.

I am a Data Science professional with three years of experience in analytics, machine learning, and data engineering, skilled at building production-ready ML solutions and data platforms. I have led initiatives such as recommendation systems, real-time dashboards, and cloud migrations that improved CTR, sales performance, query times, and cost efficiency.

My work emphasizes practical impact—using techniques from prompt engineering with Gemini LLMs to fuzzy search and cosine similarity—to drive product discovery and operational savings. I collaborate across functions, automate data workflows, and continuously learn to apply advanced ML/AI techniques for measurable business outcomes.
