What I'm looking for

I'm looking to build reliable, high-scale backend and payment infrastructure, with ownership of distributed workflows, event-driven systems, and products that deliver measurable customer and business outcomes.

At Aspire, I build payment infrastructure including distributed orchestration workflows, ACH, Wire, and Check integrations, and an FX routing engine that improved success rates by 40% while reducing transaction costs by 18%.

Previously at Factors.AI, I built real-time anomaly detection processing 2M+ events daily for 250+ SaaS companies, usage-based billing that contributed to 2x MRR growth, and enterprise authentication that reduced onboarding time by 70%.

I've also built telemetry, ranking, and collaboration integrations, along with Behavix, an event-driven AI product analytics platform handling 1M+ events per day. I work across distributed systems, microservices, Kafka pipelines, cloud infrastructure, and reliable workflow automation.
