Hire the Best Bitcoin Developers

I'm a BTA-certified Blockchain Developer and Data Scientist with 3+ years of professional experience spanning Ethereum, BSC, TRON, and Polygon -building tokens, stablecoins, DeFi protocols, and decentralized platforms -combined with hands-on expertise in data analysis, machine learning, and LLM-based systems. On the blockchain side, I build and audit smart contracts end-to-end: from novel DeFi concepts to forking and customizing existing protocols, with strong Solidity fundamentals and constant tracking of emerging DeFi trends. On the data/AI side, I work across the full pipeline-cleaning and structuring raw data, designing SQL databases, and building Power BI/Excel dashboards for clear, actionable reporting. I also build ML pipelines (classification, prediction models) and work with multimodal and LLM systems, including retrieval-augmented generation, embedding-based search, and evaluating LLM performance on specialized/low-resource language tasks. I enjoy projects that combine both worlds too, such as AI-driven mechanisms for stablecoin systems, and I'm always open to novel or hybrid ideas.
