I've spent my continuous tenure since 2021 building retail technology across Casa Retail AI and BillingStudio, from CRM event infrastructure to an offline-first point-of-sale platform.
At Casa Retail AI, I architected a Kafka-to-ClickHouse pipeline processing millions of events daily with sub-second latency for 100+ retail tenants. I also built CRM services, campaign execution, Commerce Connect integrations, Shopify flows, and a highly available ClickHouse cluster.
As BillingStudio's lead and founding engineer, I architected a multi-tenant POS platform with OAuth2/OIDC, Kafka streaming, location-scoped access control, offline synchronization, and cloud-to-edge catalog syncing. I built its Electron desktop POS, React admin console, real-time dashboard APIs, and receipt-template engine.
I enjoy designing systems from scratch and making complex data, sync, and operational workflows reliable at scale. My work spans Node.js, NestJS, React, Scala, Kafka, ClickHouse, PostgreSQL, Docker, and offline-first architecture.
