Led by Vo Huu Tin in Ho Chi Minh City, Vietnam. We design and deploy Spatial-Temporal Graph Neural Networks (ST-GNN), distributed Big Data pipelines, WebGIS decision support systems, and high-security enterprise databases.
Spatial Decision Support Systems (DSS) combining PostGIS, OpenLayers, Leaflet.js, and Spatial-Temporal Graph Neural Networks.
Distributed processing with Apache Hadoop, PySpark, HiveQL, and multidimensional OLAP Cubes using Kimball frameworks.
Fine-grained access control, Virtual Private Database (VPD/DBMS_RLS), Oracle Label Security (OLS), and auditing architectures.
Multivariate forecasting, XGBoost/Random Forest pipelines, RFM segmentation, and FP-Growth association rule mining.
Full-stack WebGIS Decision Support System applying Spatial-Temporal Graph Neural Networks (ST-GNN) and multivariate Random Forest models for salinity intrusion forecasting and automated hydraulic sluice gate operation scheduling.
Distributed data mining architecture processing 2,000+ industry job postings. Implemented automated feature extraction, topic modeling, benefit classification, and Random Forest regression for compensation benchmarking.
Comprehensive analytical pipeline featuring RFM customer value segmentation, FP-Growth association rule mining for cross-selling, review sentiment analysis, and delivery delay classification using XGBoost, Random Forest, and Logistic Regression.
Enterprise security policy design enforcing row-level isolation and mandatory access control across Admin, Promotion, and Point-of-Sale modules using Virtual Private Database (DBMS_RLS), Oracle Label Security (OLS), and Fine-Grained Auditing.
