🌌 About Me

I’m a Machine Learning Engineer focused on NLP, LLMs, and Transformers(more classical approach).
My work blends engineering with research-driven modeling β€” from hierarchical transformers to LLM-assisted dataset generation, entity extraction, and large-scale text processing .

I love building systems that understand messy real-world text, uncover structure, and power analytics, recommendations, and search.

πŸ”­ Current deep-dive:
Designing a context-aware transformer that fuses sentence-level, section-level, and document-level reasoning for robust employer/entity extraction.

πŸš€ Featured Projects

πŸ”Ή Hierarchical Job Description Modeling (NLP / Transformers / Research)

A multi-level transformer architecture that integrates:
β€’ Sentence context
β€’ Section-level signals (COMPANY, SKILLS, JOB, etc.)
β€’ Document-wide TF-IDF–guided pruning
Designed for accurate entity extraction + employer detection.
Tech: PyTorch, DistilBERT, attention layers, TF-IDF scoring


πŸ”Ή AI Agent Document Analyzer

Local retrieval agent using
LlamaIndex + LangChain + Ollama models
for PDF question answering and contextual summarization.


πŸ”Ή Sephora Hybrid Recommender System

Combined content-based & collaborative filtering
for skincare recommendations with a simple Flask/Streamlit UI.


πŸ”Ή Vision-Based Anomaly Detector

Built an optical flow + LSTM system to detect heavy-object anomalies
in real-time waste-sorting conveyor footage.
