I’m a creator-builder with a strong data engineering backbone — currently working at Exist Software Labs, building data systems, automation workflows, and AI retrieval pipelines.

Outside of work, I love making things that are useful, shippable, and interesting: apps, creator tools, AI-enabled workflows, and educational content.

• Data + AI systems that actually perform in production
• Apps and experiments across mobile, web, and automation
• Creator-driven tech content around systems, tools, and growth
• Practical products that can turn into leverage, income, or opportunity

• Automated reporting workflows, reducing manual work from 4 hours to 15 minutes
• Built data pipelines processing 500K+ transactions daily
• Improved analytics/reporting performance by 94%
• Refactored pipelines with Dask, reducing runtime by 90%
• Built a production RAG system handling 1,000+ daily queries
• Implemented hybrid retrieval using BM25 + vector search

• Mayi — mobile travel utility launched on the App Store; reached #1 in Paid Travel
• Asenso — financial simulation game launched on the App Store; reached Top 5 in Paid Games

• sql-basics-2025 — companion repo for my SQL tutorial content

I like building useful things, turning ideas into shipped products, and making tech feel exciting through content.
