LedgerLoop | Modular Social Media System for SaaS (Concept) A concept social media design system for a fictional fintech startup, built for brands that need consistency without looking boring. Instead of one-off posts, I created a flexible modular layout of rounded cards, geometric shapes and one hand-drawn accent per post, so the team can produce a month of on-brand content quickly. The 3-slide carousel shows a hook slide, a stat card and a free-trial call to action. Delivered as a 4:5 Instagram carousel (1080×1350) with a desk flat-lay mockup.
