What I'm looking for

I’m looking for a backend/architecture role where I can build secure, scalable microservices and real-time systems for SaaS/ERP—partnering with product and teams, owning technical direction, and continuing to modernize CI/CD and cloud delivery.

I’m a backend developer and technical architect focused on enterprise-scale microservices, SaaS platforms, and ERP systems. I lead architecture work with a strong emphasis on scalability, security, and real-time data synchronization.

At AITC (Veda Studios), I architect and lead Mercury 360, a SaaS-based ERP platform with integrated modules including ATS, HRMS/Payroll, file management, and workspace collaboration. I’ve implemented Keycloak for centralized user management and SSO, Tyk as an API gateway for unified routing and RBAC, and an event-driven CDC approach using Debezium and Kafka for real-time synchronization.

I bring polyglot performance to core services using NestJS for primary services and Go with Fiber (via Goca CLI) for high-performance microservices. I’ve also led backend for an art e-commerce platform with live bidding and secure wallets, and enhanced video conferencing using Mediasoup and WebRTC, while mentoring teams, running code reviews, and managing daily Scrum execution.
