About me
I'm a Junior Data Engineer with hands-on experience in database design, data pipelines, and data-driven web applications.
I deliver ERDs, clean relational schemas, and documentation you can implement and maintain with confidence. I also work with dashboard data modeling, cloud pipeline planning, workflow automation, and building custom internal tools and client-facing apps.
Whether you need a solid database to build on, a pipeline to move your data, or an app to put it in front of your users, I can help you connect the dots.

I am a data engineer with hands-on experience designing and building end-to-end data pipelines. I work with cloud platforms (mainly AWS), relational databases, and data processing tools to ingest, clean, transform, and store data efficiently. I help businesses turn raw, messy data into reliable, well-structured datasets ready for analytics, dashboards, and decision-making.

I hired him to build a custom app within Slack, and it was a great experience from start to finish. He made sure the app worked exactly as intended and thoroughly tested everything before and after delivery. Even after the project was completed, he remained available to answer questions and provide support...
