About

Data Analyst transitioning into AI Engineering — combining 5 years in analytics and quality engineering with a year of hands-on, self-directed LLM and agentic AI development. Over the past year I've built real AI applications in my own time — not tutorials, but working tools: • A job-application agent (Claude API + LangChain + Selenium) that scores roles against a resume and auto-applies — 94% completion rate • A real-time speech-to-speech translator across 11 Indian languages (Sarvam AI) • RAG pipelines using LangChain, FAISS, ChromaDB, and OpenAI/Anthropic embeddings • Agentic AI projects with LangGraph, CrewAI, AutoGen, and Pydantic AI — integrated with MCP (Model Context Protocol) My edge: I understand both the business-intelligence layer AND the AI engineering layer. As a Data Analyst I built Power BI dashboards on 250K+ records, SQL pipelines that cut report time 30%, and Python ETL saving 10+ hours weekly. That data-first discipline is what keeps my AI projects production-minded, not just demos. I'm now looking to move into AI Engineering full-time and bring that same rigor to a team building LLM-powered products.

Work experience

AI/ML Engineering — Self-Initiated Projects at Independent Learning, Jan 2026 - Present · 9 mos, ▸ Self-directed AI engineering projects, transitioning from data analytics into AI engineering. ▸ Built an AI-powered job application agent that automatically searches job listings, scores them against a candidate’s resume using AI, and submits applications — reducing per-application time from 5+ minutes to under 30 seconds, with a live dashboard for tracking progress. ▸ Built a real-time voice translator supporting 11 Indian languages — speaks to it in any language, it automatically understands, translates, and speaks back in the target language. ▸ Built agentic AI systems using LangGraph, CrewAI, AutoGen, and Pydantic AI integrated with MCP (Model Context Protocol), plus RAG pipelines with LangChain, FAISS, and ChromaDB. ▸ Deployed multiple AI applications with live dashboards, API integrations, and real-time monitoring — focused on building tools that are usable by non-technical end users.
