Karthik VVS

I’m a Full Stack Developer with strong experience in building scalable SaaS platforms and ERP integration systems using NestJS, Flutter, PostgreSQL, and GCP. I’ve led projects end-to-end — from gathering requirements and architecting solutions to deploying stable, production-ready systems. My work spans backend systems with RBAC and multi-tenancy, to dynamic frontends with permission-aware UI.


I’ve also taken ownership beyond code by directly interfacing with clients, managing enhancement requests, handling production deployments, and guiding user acceptance testing. I thrive in roles that require both technical depth and the ability to collaborate across teams and with clients to drive real impact.
