Senior Full-Stack Developer – TikTok SaaS Platform

We are seeking an experienced Senior Full-Stack Developer or small development team to build a professional SaaS platform designed for TikTok LIVE creators. The platform will enable creators to connect their accounts and automatically trigger visual effects, animations, sounds, alerts, overlays, and interactive actions based on real-time events during LIVE streams. The system must process live events in real time and allow creators to establish custom rules such as triggering effects when specific gifts are sent, displaying animations on follows, playing videos or sounds when certain gift thresholds are met, and displaying overlays during battles or PK events. The platform should detect and process gifts, gift quantities, gift sender information, and other relevant live stream events while adhering to technical and legal requirements. The goal is to develop a reliable, scalable, and professional platform with independent UI/UX, codebase, infrastructure, and branding that can be offered commercially as a subscription-based SaaS. This is a fixed-rate project valued at $2500, open to remote developers globally.
