Full Stack & Systems Developer

Karachi, Pakistan

Building multi-tenant business systems and developer tools.

I'm a full-stack developer building multi-tenant SaaS platforms — venue management, inventory tracking, and financial tools that need to handle money correctly.

My current stack is .NET 10 with FastEndpoints on the backend, SvelteKit with Svelte 5 on the frontend, and PostgreSQL.

Deployed with Podman containers and Caddy as the reverse proxy.
