WORK HISTORY
Software Development Engineer @Amazon
Vancouver, BC, CA
Facilitated deprecation of monolithic recruiting system by extracting services responsible for personal data, candidate notes and document attachments, coordinating data migration of 500M+ records across multiple datasets while maintaining system availability. Initiated and lead efforts of regionalization of Amazon hiring systems infrastructure which reduced P90 latency for globally distributed users by 2-4 seconds (~20-30%, page-specific) and increased availability from ~99.7%(downtime of 26 hours/year) to ~99.97 (2.6 hours/year). Implemented a set of improvements to operational excellence SoP for customer onboarding, handling client requests and ticket resolution (including GenAI via AWS Bedrock) that cumulatively freed up to 5 developer/days per month for a team of 6 and further was extended to other teams in the org.
