Project Experience

Data Analyst | Diabetes Prediction — Comparative ML Study
R, RStudio, caret
  • Built an end-to-end ML pipeline on a clinical dataset of 16,969 records — handling missing value imputation, Z-score outlier detection, and upsampling to correct severe class imbalance.
  • Designed and evaluated five classification models — Logistic Regression, KNN, Naïve Bayes, Decision Tree, and Random Forest — using Kappa as the primary metric to avoid misleading accuracy scores on imbalanced data.
  • Identified Random Forest as the optimal model, achieving 99.85% accuracy and a Kappa of 0.9605 with Specificity of 95.38% — outperforming literature benchmarks of ~94%.
  • Applied Gini Importance analysis to identify Blood Glucose and Age as the strongest predictors; demonstrated that high model Sensitivity (0.9994) is critical in clinical settings to minimise false negatives.
Team Lead | Smart Agriculture IoT System
Raspberry Pi, Python, GPIO, Taiga
  • Led a team of 4 to design and build an automated plant-monitoring system using Raspberry Pi sensor modules to optimise crop yields and water conservation.
  • Engineered the data pipeline for soil moisture and atmospheric particulate sensors, enabling real-time monitoring of hydration levels and environmental health.
  • Developed a dynamic alerting system that informed users exactly when and where irrigation was required, reducing potential water waste.
  • Facilitated Agile workflows using Taiga for project management, overseeing backlog grooming, sprint planning, and task delegation to ensure consistent project velocity.
Database Developer | Relational Database Design
Oracle, SQL (PL/SQL)
  • Wrote complex SQL queries including multi-table joins, subqueries, and aggregate functions to extract business insights and ensure data integrity.
  • Created Entity-Relationship Diagrams (ERDs) to map data architecture and guarantee referential integrity across all tables.
  • Designed and implemented a full relational database architecture using Oracle PL/SQL, with normalisation to 3NF and query optimisation principles.
