What I'm looking for

I'm looking to lead the architecture and delivery of mission-critical distributed platforms, partnering across product and operations to solve complex global-scale problems and build high-performing engineering teams.

At Multiplier, I lead the technical delivery of a global payroll platform, transforming a tightly coupled system into domain-driven microservices orchestrated by state-machine workflows. I direct a seven-engineer team delivering provider integrations, reconciliation pipelines, and automated statutory document distribution.

Previously at Amazon, I built a serverless real-time streaming platform that reduced data latency from roughly 48 hours to under five seconds. I also delivered fraud-prevention services that saved more than $50M annually and a dynamic purchase-limit platform that drove over $10M in savings.

I've also modernized integrations at Aircall and led teams building IoT automation, edge-to-cloud gateway, and Voice of Customer analytics platforms at Nagarro. I work across Kotlin, Java, Go, Python, AWS, Kafka, and high-concurrency event-driven architectures.
