Senior Platform Engineer and Software Architect with 7+ years of experience designing, building, and operating production-grade cloud-native SaaS platforms.
My experience spans the full software delivery lifecycle—from architecture and backend engineering to cloud infrastructure, DevOps, and distributed systems. Throughout my career, I have led the technical delivery of products from Pre-MVP to production, building scalable platforms used by enterprise customers across multiple industries.
Currently serving as Chief Technology Officer at Otraverse, where I lead the architecture and engineering execution of a multi-tenant immersive commerce platform across backend engineering, cloud infrastructure, DevOps, distributed systems, and platform architecture.
I enjoy building production systems that are scalable, observable, resilient, and designed for long-term maintainability.
