👋 About Me

I'm a passionate Data Engineer & Full-Stack Developer who loves building end-to-end systems — from raw data pipelines all the way to polished user interfaces. Whether it's orchestrating Airflow DAGs, tuning PySpark jobs on Databricks, or crafting a React frontend that speaks to a Golang API, I enjoy the full journey.

I'm actively looking for roles where I can make an impact at scale — teams that care about clean architecture, good data, and shipping things that matter.

"Data is the new oil — and I'm here to refine it."

🎯 Open To Roles

Role What I Bring
Data Engineer End-to-end pipeline design, orchestration, warehouse optimization
Full-Stack Developer React + Golang/Node backends, REST APIs, cloud-native apps
