Bubble.io
Vobiz
The Problem
PSN Financial Services had no technical infrastructure - all HR, CRM, and payroll processes were manual. They needed a full enterprise SaaS built end to end with no internal tech team.
My Role — Sole architect and developer, 0 to production
The Solution
Built a React 19 + TypeScript SPA with feature-sliced architecture. Implemented dynamic RBAC using role_permissions tables + Supabase RLS + JWT custom claims. Integrated VoIP using Vobiz.ai + Supabase Edge Functions and Realtime. Deployed Flutter mobile apps (PSN Connector) to Play Store.
The Outcome
Live in production and actively used daily by the PSN Financial Services team. Replaced all manual processes across HR, CRM, and payroll.
