Built the full stack including authentication, role-based access control, organization isolation, database architecture, realtime messaging, and core CRM workflows.
Built the application end-to-end, including authentication, role-based access control, organization-level data isolation, database architecture, REST APIs, realtime messaging, subscription management, and core CRM workflows.

About
I'm a full-stack developer who learned by building things from the ground up. What started as curiosity about how software works turned into building complete applications. From React and TypeScript interfaces to Node.js APIs, PostgreSQL databases, authentication, and multi-tenant systems.
I enjoy taking an idea and turning it into something real. My main project is a SaaS CRM that I built and evolved across the entire stack, which taught me as much about architecture, debugging, deployment, and product decisions as it did about writing code. I care about understanding what I build, not just making it work.
