At eSparkBiz Technology Pvt. Ltd., I optimized Node.js and PostgreSQL APIs, reducing average response time by 25% through query restructuring and indexing. I also designed PostgreSQL schemas and implemented dynamic permission management across client platforms.
On projects including KhmerHome, Pet App, Smackdab, and The ASL Shop, I developed backend features for SaaS platforms, including RBAC, data migration, and integrations. On Pet App, automated email reminders improved appointment compliance by 30%.
