01 / SELECTED WORK
Selected contributions across healthcare and AI.
AGENTIC AI · PRODUCTION OPERATIONS
Built an internal AI copilot that correlates technical documentation, user journeys, runtime data, and client-side errors to support production investigations.
30% less investigation time
SEMANTIC SEARCH · DISCOVERY
Designed semantic influencer search using vector embeddings, replacing rigid filters with natural-language retrieval.
~7 minutes → under 1 minute
CONVERSATIONAL AI · VIDEO WORKFLOWS
Built a conversational video-editing chatbot for natural-language changes, including lip-sync adaptation to new scripts and product replacement in existing influencer videos.
02 / EXPERIENCE
From mobile interfaces to cloud infrastructure.
From individual contribution to team leadership.
MAR 2025 — SEP 2026
Senior Software Engineer · Cloud & Distributed Systems
Contributed to the transition from a monolithic healthcare platform to independently deployable microservices with service-owned data. Built AWS infrastructure with CDK and asynchronous workflows using queues and WebSockets.
DEC 2021 — MAR 2025
Hands-on Tech Lead · AI & Full Stack
Built and led development of a cross-platform app covering the influencer campaign lifecycle, plus a shared web and mobile admin platform. Led and mentored three engineers through architecture decisions, code reviews, and technical guidance.
FEB 2019 — DEC 2021
Full Stack Software Engineer
Built enterprise web and mobile applications for a major insurer, spanning payments, renewals, reporting, and operations. Helped automate approximately 30% of manual processes across applications serving thousands of users.
