Data Scientist and AI Engineer focused on building practical, end-to-end AI systems, including RAG and agentic workflows. I combine strong engineering with data-driven thinking, and explore art as a creative counterbalance.
Featured Projects
Major projects from professional work
Regulatory News Extraction Pipeline
Robi Axiata
Autonomous regulatory intelligence system that searches, fetches, and extracts news across 60+ countries with AI-powered topic classification (25 categories), hierarchical reporting, and emoji-highlighted source credibility.
Travel Claim Validation Pipeline
Professional
Automated end-to-end pipeline that validates employee travel expense claims using Claude Sonnet for PDF receipt extraction, fuzzy name/amount matching, policy-based cap enforcement, and location plausibility checks.
RAG-Based Procurement Chatbot
Robi Axiata
Built RAG chatbot using financial documents with hybrid vector-BM25 retrieval, context-aware reranking, and multi-turn conversational memory. Supports Claude and Ollama backends.
Customer Churn Prediction System
Optimizely
End-to-end ML system with automated pipeline on AWS, monthly retraining, model selection, and deployment using Docker, Kubernetes, and Argo Workflows.
Social Media Sentiment Analysis
Robi Axiata
Developed tool tracking sentiment, intent, emotion, and issues from Facebook comments across major telecom providers with live Tableau dashboard.
Survello Surveillance Platform
NybSys

Thoughts on AI, engineering, and more
Building a Personal AI Research Feed: Scraping LinkedIn, Scholar, and X into an Obsidian Vault
How I built a local Python system that automatically pulls AI-engineering content from three sources, classifies it with Claude, and writes structured notes into Obsidian — with deduplication, date parsing, and a budget-aware research tracker.
RAG-Based Procurement Chatbot: Building Accurate Financial Document Search with Vector Embeddings
How I engineered a retrieval-augmented generation system for financial documents using hybrid search, vector embeddings, and LLM integration to answer procurement questions with precision and context awareness.
