Summary

Senior software engineer with deep experience in distributed systems, event-driven architecture, and GenAI automation. Currently at Salesforce Hyperforce AI, building agentic SDLC tooling and IDE plugins. Previously nearly 6 years at Amazon (FAANG / Big Five) Finance Automation — one of the most demanding engineering environments in the industry — where he co-architected a large-scale event-driven vendor-payments platform, built a self-service rule engine, and shipped a production LLM-driven reconciliation engine. Strong hybrid profile: can both design high-throughput distributed systems and ship production GenAI inside them.
