Hi, I’m Aseem 👋

Data Scientist / ML–AI Engineer in Dublin, building practical AI systems end-to-end — from retrieval and agentic reasoning to deployment and observability. Previously @ Innovaccer. I care about reliability, clear interfaces, and shipping useful tools.

🚀 What I’m building now

StatsEye — a research assistant for Ireland’s CSO data
Hybrid retrieval + agentic Python analysis on CSO datasets, wrapped in a conversational UI (Chainlit), deployed on GCP (Cloud Run). Makes finding the right table and getting first insights a one-message job.

Designed to transform how researchers, analysts, and curious minds interact with statistical data available on Data-CSO website. Try the StatsEye-Assistant now!

Tools and frameworks used:

  • LangGraph (for agent orchestration)
  • FAISS Vector DB (for storing vector embeddings)
  • Gemini 2.5-flash (API) and Gemini embedding model
  • Redis (for checkpointing and long-term memory storage)
  • Chainlit (UI-wrapper on React front-end)
  • Google Cloud Run (for deployment)
  • Docker (for containerising)

Check out my GitHub repo here.

🧰 Core stack

  • Languages: Python, SQL
  • AI/IR: LangGraph, LangChain, CrewAI, RAG (BM25 + dense + LLM rerank), FAISS
  • Apps & Infra: GCP (Cloud Run, Artifact Registry), FastAPI/Flask, Docker, Kubernetes, Redis/Celery, Chainlit, Streamlit
  • Data & Viz: Pandas, Seaborn, NumPy, Folium, Jupyter

  • Data-Zenith (Hack-weekends 2024) — Enterprise search + analytics over org knowledge bases (RAG + agents).
    Repo: A-Raghav/hack-weekends-2024
  • Flask + Celery on Kubernetes — Minimal worker pipeline with Redis broker/back-end; manifests + compose.
    Repo: A-Raghav/Flask-App-with-Celery-Worker-on-Kubernetes
  • Market Intel (CMHC vs MaineHealth) — Geo EDA with interactive heatmaps (market share, leakage, proximity).
    Repo: A-Raghav/EDA-CMHC-Maine-Market-Intel

📌 Focus areas

  • Retrieval that actually retrieves (hybrid ranking, table/entity linking)
  • Agentic workflows with safe tool-calling and review gates
  • “First-5-minutes” insights: fast EDA, charts, and citations straight from chat
  • Clean deployment paths (containers → Cloud Run/K8s) and observability
