01 — About

Turning data into decisions.

I'm a results-driven Data Engineer & Full-Stack Developer with practical experience architecting responsive web applications, RESTful APIs and cloud-integrated data workflows.

My toolkit spans Python, SQL, JavaScript, React.js, Node.js and MongoDB, alongside hands-on knowledge of Databricks, Apache Spark (PySpark) and AWS. I also work deeply in computer-vision annotation pipelines, dataset QA and workflow automation — where a single mislabeled frame can cost a model its accuracy.

Currently I split my time between high-precision dataset work for AI teams at Intellabel by Sunix AI and building production-ready MERN applications.
