Ragulan Gopalapillai

I’m a Tech Lead with 6+ years of experience designing high-availability, cloud-native systems across e-commerce, PropTech, and IoT, with a proven focus on turning complex business needs into scalable, revenue-driving solutions. I lead cross-functional efforts to deliver secure, stable architectures, especially around OAuth2/SSO identity management and gRPC-based microservices.

At Mobile App Mart, I led development for ConferWith and Filey Property, engineering scalable architectures that resolve complex design bottlenecks to improve system stability. I architected and implemented centralized Authentication and Authorization frameworks to secure cross-platform services, translated product requirements into technical roadmaps with product teams, and built quality engineering practices with rigorous code review standards and automated testing to ensure 99.9% deployment reliability.

Earlier roles strengthened my end-to-end delivery and security depth: I re-engineered a multi-tenant B2B platform into a scalable B2C architecture, designed advanced OAuth2 authentication and authorization protocols, and optimized performance for high availability. At Sysco LABS and Pagero, I oversaw full-stack delivery, conducted root cause analysis to improve reliability and standards compliance, and built secure integrations using Single Sign-On (SSO), Multi-Factor Authentication (MFA), gRPC microservices, RabbitMQ messaging, and Cloud Foundry with Docker—supported by strong engineering leadership with Product Owners to define MVP requirements.
