I solve problems that matter while driving quantifiable business results. At Amazon, I'm revolutionizing customer service through Conversational AI, building platforms that understand context, reduce friction, and deliver human-like interactions at scale. My latest ML platform migration generated $140K annual savings while enabling new AI capabilities. Before Amazon, I spent 9 years at Bank of America reimagining how financial institutions handle risk. I architected cloud-based systems that transformed daily risk processing for 200K+ trades that support critical trading decisions. ๐‚๐จ๐ซ๐ž ๐„๐ฑ๐ฉ๐ž๐ซ๐ญ๐ข๐ฌ๐ž: โ€ข ๐€๐ˆ ๐๐ฅ๐š๐ญ๐Ÿ๐จ๐ซ๐ฆ ๐€๐ซ๐œ๐ก๐ข๐ญ๐ž๐œ๐ญ๐ฎ๐ซ๐ž: End-to-end LLM integration and streaming API development. โ€ข ๐—™๐—ถ๐—ป๐—ฎ๐—ป๐—ฐ๐—ถ๐—ฎ๐—น ๐—ฅ๐—ถ๐˜€๐—ธ ๐—ฆ๐˜†๐˜€๐˜๐—ฒ๐—บ๐˜€: Real-time and batch analytics for trading, compliance, and market risk. โ€ข ๐—ฃ๐—ฒ๐—ฟ๐—ณ๐—ผ๐—ฟ๐—บ๐—ฎ๐—ป๐—ฐ๐—ฒ ๐—ข๐—ฝ๐˜๐—ถ๐—บ๐—ถ๐˜‡๐—ฎ๐˜๐—ถ๐—ผ๐—ป: Database and system improvements delivering hours-to-minutes performance gains. โ€ข ๐—œ๐—ป๐—ป๐—ผ๐˜ƒ๐—ฎ๐˜๐—ถ๐—ผ๐—ป ๐˜„๐—ถ๐˜๐—ต ๐—ฃ๐˜‚๐—ฟ๐—ฝ๐—ผ๐˜€๐—ฒ: Building AI that genuinely improves user experiences while driving cost savings. โ€ข ๐—ง๐—ฒ๐—ฐ๐—ต๐—ป๐—ถ๐—ฐ๐—ฎ๐—น ๐—Ÿ๐—ฒ๐—ฎ๐—ฑ๐—ฒ๐—ฟ๐˜€๐—ต๐—ถ๐—ฝ: Cross-functional migration projects with quantifiable business outcomes. ๐—ง๐—ฒ๐—ฐ๐—ต๐—ป๐—ผ๐—น๐—ผ๐—ด๐—ถ๐—ฒ๐˜€: Python, Java, Kotlin, AWS, Machine Learning, NoSQL, Kafka, Spark, Typescript I thrive on solving complex technical challenges that drive real business value.
