I’m a Full-Stack Software Engineer with 3+ years building multi-tenant retail CRM and marketing-automation SaaS at scale. I specialize in TypeScript / Node.js backends and React frontends, with hands-on data engineering across Kafka and ClickHouse. I’ve delivered measurable impact in fast-paced Agile teams, including 10x campaign throughput, real-time data synchronization, and CPaaS/WhatsApp integrations. I enjoy designing systems that stay reliable under load—especially in shared, multi-tenant environments. At Casa Retail AI, I developed a PIM system with bi-directional POS integrations (SAP, Wondersoft), syncing per-tenant products, inventory, and variants across PostgreSQL and ClickHouse. I also built tenant-level parallel job limiting to prevent queue starvation in a shared background job system. On the product side, I architected the concurrent dispatch layer for campaign messaging, built a multi-tenant Ticket Desk (CRM helpdesk) with omnichannel tickets and tenant-isolated SLA tracking, and shipped CPaaS / WhatsApp integrations across 4+ providers. I bring strong end-to-end ownership—from Kafka-driven real-time/nightly batch sync to a customer-facing React dashboard with cohort and journey rules.
