01 / The Challenge

What needed to be solved

Media-heavy platforms often become slow and expensive to run as user activity grows. Traditional database setups make dozens of separate requests just to load a single home feed—fetching posts, user profiles, media galleries, likes, and saved states separately—leading to sluggish page loads and laggy messaging.

02 / Our Solution

How we engineered the platform

We engineered Zeloria around a streamlined Next.js App Router frontend paired with a custom PostgreSQL database layer on Supabase. By consolidating feed assembly into a single optimized database function and pairing it with cursor-based pagination and live WebSocket channels, the platform loads complex media feeds in a single roundtrip while supporting instant messaging and database-enforced account privacy.

03 / Key Deliverables

Core features shipped to production

Single-Roundtrip Feed Engine

Replaced slow multi-query waterfalls with a unified PostgreSQL function that returns posts, profiles, media, and engagement states in one fast request.

Real-Time Messaging & Presence

Built live direct messaging, active user status indicators, and instant activity notifications powered by real-time database triggers.

Database-Enforced Privacy Controls

Implemented public and private account permissions directly at the database security layer so sensitive content is protected by default.

Adaptive Desktop & Mobile Experience

Designed a responsive navigation rail for desktop users and a streamlined mobile dock with zero-flicker theme switching.
