Chamod

Data Engineer in the making.

Building production-grade data pipelines, streaming platforms, and lakehouses. I write Python that moves data, SQL that finds truth in it, and systems that keep it honest.

About Me

I'm a final-year Data Science undergraduate at SLIIT, Malabe, with hands-on experience spanning the full data engineering stack from ingestion and transformation to streaming pipelines, cloud deployments, and BI/OLAP reporting.

My background covers Python, Spring Boot, the MERN stack, R, PostgreSQL, MongoDB, Docker, SSIS/SSAS, AWS, and Apache Airflow, plus applied statistics and machine learning (scikit-learn, XGBoost, hypothesis testing). I bridge the gap between data science theory and production engineering practice.

I'm currently building out my data engineering stack - AWS, Airflow, dbt, and Redshift - through hands-on projects, while targeting internship roles at Sri Lanka's leading IT companies and competitive remote positions abroad.

Work & Projects

01
Airflow dbt AWS S3 Redshift Serverless Terraform Great Expectations

Olist E-Commerce Data Warehouse ⭐

End-to-end AWS warehouse processing 9 source tables (1.5M+ rows) through Bronze/Silver/Gold medallion architecture. Kimball star schema in dbt (4 facts, 4 dims), two-layer data quality strategy (Great Expectations + 25 dbt tests), least-privilege IAM across three identities, and Dockerized Airflow (CeleryExecutor) with a data-quality gate.

02
SSIS SSAS Power BI SCD Type 2

DataCo Supply Chain Data Warehouse & BI Platform

Star-schema warehouse (1 fact, 5 dims) from a 180,000+ row multi-source dataset. 3-package SSIS pipeline with SCD Type 2, SSAS OLAP cube with 4 hierarchies and 2 KPIs, and 4 interactive Power BI reports with drill-through navigation.

03
Python scikit-learn XGBoost Streamlit

KiwiStay AI - Airbnb Price Prediction

Rebuilt a university project from scratch: engineered 38 features from an 85-column, 46,321-row NZ Airbnb dataset, dropped target-leakage columns, and bundled preprocessing + XGBoost into one scikit-learn Pipeline. R² = 0.773 (MAE NZD 70) - a 35% relative improvement over the original R² = 0.57. Deployed live on Streamlit Community Cloud.

04
R Statistical Modelling OULAD

Learning Analytics: Engagement vs. Academic Success

Hypothesis-driven statistical analysis of 32,593 students (OULAD dataset). Led data preparation and feature engineering, identifying MNAR missingness in assessment scores. Findings: high-engagement students were 8× more likely to succeed (Cohen's h = 1.18); ANOVA showed engagement explained 52% of outcome variance; logistic regression reached 75-78% accuracy, AUC > 0.80.

05
Spring Boot 3 React 19 PostgreSQL Docker

Smart Campus Operations Hub

Full-stack university operations platform (5 modules, 5-person team). Built the maintenance/incident ticketing module: submission with Cloudinary image attachments, full OPEN → IN_PROGRESS → RESOLVED → CLOSED workflow, technician assignment, comment threads, and Lucene-powered similar-ticket detection.

06
MERN Stack JWT Cloudinary

Station 360 - Vehicle Service Booking System

Led a 5-person team building a full-stack vehicle service booking platform (shared backend, user/admin/employee frontends). Owned booking management: smart time-slot logic, holiday/late-booking handling, lifecycle tracking, PDF report exports, and email/conflict-prevention logic.
