What I'm looking for

I’m looking for Python/SQL and LLM-evaluation work—building RAG and data-driven dashboards while improving data quality through rigorous correctness, prompt, and response-quality reviews in a collaborative, remote-friendly environment.

I’m a Software Engineer and Associate Analyst with 3.5+ years of hands-on experience across Python, SQL, data analysis, AI-powered applications, full-stack development, backend APIs, dashboards, and LLM evaluation workflows. I enjoy turning messy inputs into structured outputs—then validating correctness, clarity, and alignment with requirements.

In my recent Associate Analyst work at Zepto, I focus on data review, operational analysis, reporting, and quality-focused workflows. I analyze structured records, validate outputs, detect inconsistencies, compare data points, and deliver clear summaries that support business decisions—using Excel-style analysis, SQL-style reasoning, and strong documentation habits.

As a software engineer and project builder, I design and deploy AI and full-stack systems with FastAPI, React/Next.js, TypeScript, PostgreSQL, and AWS—often wrapping them with reliable REST APIs, asynchronous workflows, and performance-minded backend logic. I also review AI-assisted outputs for relevance, factuality, instruction-following, completeness, formatting, and hallucination risk, and I turn evaluation findings into actionable improvements.

I’ve strengthened this focus through AI evaluation and GenAI experience, including prompt-based response review and RAG/vector search workflows. My projects—from an AI resume analyzer to a Scale-RAG document assistant—combine structured data processing, retrieval-backed answers, and quality validation, while staying grounded in repeatable testing and clear written communication.
