I’m a backend software engineer with 5+ years of experience building event-driven microservices and REST/gRPC APIs across fintech and cloud platforms, including Coinbase. I focus on backend automation, performance optimization, and operating reliable distributed systems at scale.

At Hewlett Packard Enterprise, I developed REST APIs in Go for HPE GreenLake’s webhook notification platform, powering core registration, ingestion, and delivery services supporting 100K+ CloudEvents daily. I designed proactive webhook health monitoring to detect unreachable endpoints and automate state transitions to prevent delivery attempts to failed endpoints. I also built AWS Lambda-based mock webhook endpoints to remove third-party dependencies, reduced integration testing time by 60%, and improved event delivery reliability and reduced latency by 25% using sharding, exponential backoff retry logic, and Redis caching.

At Coinbase, I developed and owned a gRPC-based Transaction and Wallet service for Coinbase Prime, migrating 15 legacy Ruby endpoints into a consolidated Golang microservice. I reduced API response time by 70% while supporting deposits, withdrawals, transfers, and balance checks for institutional clients serving $100B+ in assets. I served as primary on-call for Settlements and Transfers, triaging 10+ production incidents, and delivered a time-critical ETH migration killswitch to ensure zero-downtime blockchain transition.

I’m now expanding into AI-adjacent backend development, focusing on LLM APIs and agentic workflows. I bring a systems mindset from backend automation and distributed operations work, with a track record of mentoring and cross-team collaboration.
