Data Engineer, Analystt.AI, India

Dec 2021 - Apr 2022

A lead generation company aggregating vast amounts of financial and corporate data for decision-making.

  • Optimized query performance by migrating 20 million records from SQL to Elasticsearch leading to faster searches.
  • Engineered an NLP pipeline (spaCy NER, regex parsing) to extract 50,000+ structured records from unstructured PDFs.
  • Architected 12+ Python scrapers (Scrapy, Selenium) and API integrations to extract data from government & public sources, automating updates for 20k+ records daily and saving 8 hours/week, improving data freshness for decision-making.
  • Engineered an internal analytics platform using React/FastAPI to audit data quality, eliminating the marketing team's dependency on engineering support for lifecycle management.

Flutter Developer, Databyte Services & Systems, India

Dec 2021 - Apr 2022

  • Collaborated on an Industry-Academia Partnership project (Student Research Group) constructing a Flutter image management app with tagging for efficient organization, reducing image searching by 70%.
  • Improved performance, and added features including tags, duplicate detection, geo-tagging, and image enhancements.

Projects

Autonomous Grocery Pricing Agent (UNSW Founders Peter Farrell Cup participant) | Video Demo

Jan 2025 - Present

  • Developed a real-time price intelligence agent using Ollama for semantic product matching across major retailers (Woolworths, Coles, IGA). Validated product-market fit via interviews with 50+ shoppers and 10 local grocers.
  • Designed a multi-node LangGraph workflow with tool-use, Human-in-the-Loop (HITL) interrupts, and structured post-processing.
  • Built async FastAPI with custom scrapers to aggregate live pricing; used LangSmith for observability and implemented session-based thread for persistent conversations, reducing manual price comparison time by 86% for end-users.

Plastic Detection (1st/770 teams from 19 countries, Kyndryl Hackathon) | Video Demo

Jul 2023 - Sep 2023

  • Developed a YOLOv8 ensemble with DBSCAN, resulting in 49.18% uplift in recall compared to a single YOLOv8 model.
  • Reduced model training time by clustering 6k images via VGG16 embeddings, PCA, and K-Means to reduce data redundancy; manually annotated and augmented a 300-image Saigon River dataset to handle local environmental edge cases.
  • Led a 4-member team to engineer a plastic drift algorithm mapping movement to water bodies using hydrographic data; integrated FastAPI, Power BI, and Dropbox for automated data pipeline.

Predictive Maintenance Railway | IEEE Paper

Jun 2023 - Aug 2023

  • Built a fault detection pipeline, applied LSTM, Random Forest, XGBoost, and Isolation Forest algorithms to predict faults in 1.5M+ multivariate time series data from train sensors with LSTM standing out with 95% recall where failures constituted <1% of data.
  • Implemented Explainable AI, including SHAP and Global Surrogate Models, to interpret ensemble predictions and isolate the contribution of raw sensor inputs vs. temporal engineering.
  • Developed Grouped Permutation Importance to handle time-series multicollinearity, validating the true predictive signal of engineered rolling window and lag features.
