I own the whole path: idea → architecture → frontend → backend → integrations → cloud → production. My focus is systems that stay reliable under real use: auth, payments, scheduling, async workflows, and AI features that are wired into the product instead of bolted on.

A SaaS platform designed to simplify invoicing for freelancers and agencies while automating repetitive payment workflows. Instead of behaving like traditional accounting software, PaperChai focuses on speed, automation and payment intelligence.
|
A reusable authentication and authorization platform designed for SaaS applications that need organizations, users, applications and isolated tenant access. The goal is to move authentication infrastructure outside individual products so multiple applications can share a consistent identity platform.

A cross-platform billing application built with a separate mobile frontend and backend API architecture. The project separates presentation, business logic and persistence instead of treating the mobile application as a standalone client. |
