About

Data platforms designed for scale, reliability, and business reporting.

Data Engineer with 4+ years of experience designing and building scalable data platforms, data warehouses, and large-scale ETL/ELT pipelines. Experienced in processing billions of records using modern Big Data technologies including Apache Spark, Airflow, Kafka, and cloud-based data architectures. Skilled in implementing Medallion Data Platforms (Bronze–Silver–Gold), optimizing distributed data pipelines, and building enterprise reporting systems that support high-performance analytics and data-driven decision making. Passionate about distributed systems, real-time data processing, and modern Data Lakehouse architectures, with a strong focus on performance optimization, scalability, and reliable data infrastructure.

AI & Data Engineering

AI-Ready Lakehouse Architecture

AI-Driven Processing

By dividing the data pipeline into distinct layers, I ensure data is primed for Machine Learning. Raw data lands in the Bronze layer, gets cleaned in the Silver layer, then passes through AI/ML Processing for predictions, before serving high-performance insights in the Gold layer.

Creative Builder

Turning messy data problems into clear, useful systems.

I like working at the intersection of engineering discipline and creative problem-solving: mapping business questions, shaping reliable pipelines, and building tools that make data easier for teams to use.

Hobbies

Traveling, observing systems, and sharing what I learn.

01

Travel

I enjoy exploring new cities, local culture, and everyday systems. Travel gives me fresh perspectives on how people move, decide, work, and use technology.

02

Sharing Experience

I like turning practical lessons into short notes, videos, and blog posts so other engineers can avoid common mistakes and learn faster.

03

Creative Work

Outside of data platforms, I care about visual storytelling, personal branding, and making technical ideas easier to understand.
