Building data pipelines that process crypto market data, trading signals, and real-time analytics. Started with my own trading needs but turns out lots of companies struggle with turning messy data streams into something they can actually use. I handle the full stack: data ingestion from multiple sources (APIs, websockets, databases), cleaning and transformation, storage optimization, and building dashboards or alerts on top. Heavy use of AI tools for generating pipeline code and debugging data quality issues. Current work includes: crypto intelligence platforms, market sentiment analysis, automated trading signal generation. The focus is always on reliability - if your data pipeline breaks at 3am, your business stops working.
