At Demandbase, I designed and built an in-house email delivery microservice that replaced SendGrid and Mailgun, saving $1,000+ per month. I also architected an asynchronous pipeline with Amazon SQS and Amazon SES, and implemented reliability controls and production monitoring.

At Housing.com, I optimized property listing APIs to reduce response time by 40% and built a fraud detection and scoring engine that reduced fraud reports by 70%. I also reduced P99 latency for create workflows by 81% and mentored two engineers.
