A cross-platform medical application designed to connect doctors, patients, and hospital administrators under one unified system.
Data Engineer (Product Analytics Platforms)
Delivered production-grade ingestion pipelines for customer, order, and product datasets, improving reporting reliability by standardizing schemas and automating loads and transformations into Snowflake.
Built resilient orchestration in Airflow (retries, SLAs, backfill-safe patterns), reducing failed runs and recovery time by implementing idempotent incremental processing.
Implemented a Snowflake medallion architecture (Bronze/Silver/Gold), accelerating downstream analytics iteration by separating raw, cleaned, and curated metric layers.
Developed dbt transformation models (incremental logic + macros), increasing consistency of KPIs by centralizing business logic and documentation in dbt.
Strengthened data quality and observability, reducing stakeholder-facing data issues by adding dbt tests (freshness/uniqueness/relationships) and automated alerting
Data Engineer
Automated end-to-end ETL/ELT pipelines for e-commerce analytics, eliminating manual reporting workflows by ingesting Shopify, payments, and marketing data into Snowflake with incremental loads.
Designed event-driven tracking foundations, improving funnel visibility and debugging speed by defining event contracts, schema versioning, and downstream consumption tables.
Owned pipeline scheduling and reliability in Airflow, reducing broken dashboards by implementing SLAs, retries, partition-aware loads, and safe reprocessing logic.
Optimized Snowflake performance and cost, lowering runtime/warehouse usage by tuning queries, selecting appropriate warehouse sizes, and using incremental strategies
Built an end-to-end ELT pipeline that ingests football-data.org REST endpoints (competitions + match windows/backfills), lands immutable raw JSON in MinIO (Bronze) with run-based partitioning, and loads payloads into Snowflake.
Implemented idempotent loaders using a Snowflake table to guarantee safe re-runs and prevent duplicate ingestion across incremental and backfill workflows, improving reliability for scheduled orchestration.
Designed and built an end-to-end data pipeline for The Movie Database (TMDB), ingesting API data into a modern analytics stack using Python, MinIO, Snowflake, dbt, and Airflow-ready date-partitioned workflows.
Engineered a Bronze ingestion layer that captured raw TMDB JSON payloads in MinIO and loaded them into Snowflake as semi-structured data with full lineage metadata, including partition date, run ID, object key, payload hash, and load timestamps.
End-to-end ML pipeline to predict customer churn with interpretable logistic regression. Includes EDA, data cleaning, engineered engagement/loyalty features, class-balanced training, and business-focused insights.
Feature engineering: engagement_score, loyalty_score, balance_salary_ratio, high-value & underbanked flags
