Role
Solo Full-Stack Developer
Shopify merchants who want to advertise properly run into the same wall repeatedly: platform-specific creative needs a designer, video (the format that actually converts) needs a production budget, copy needs rewriting per niche, and Facebook and TikTok each demand their own dashboard. Finding UGC creators who understand the product is its own manual, scattered process.
An end-to-end platform, architected and built solo across four coordinated applications — a NestJS backend, a merchant dashboard, a creator dashboard, and a Shopify-embedded app. A merchant connects their store and picks a product; the platform generates ad images through a custom Gemini-based creative pipeline, produces 30-second vertical video ads through a three-segment Veo-3.1 pipeline, writes niche-aware copy with GPT-4, and pushes the finished campaign straight to Facebook and TikTok's ad APIs. A "Growth Mode" layer watches live performance and automatically regenerates underperforming variants on its own schedule.
Alongside the ad engine sits a full UGC marketplace: creators list services and a portfolio, merchants hire and pay through Stripe Connect, and the two sides coordinate through real-time chat and a formal order-revision workflow.
20+ backend modules, 120+ API endpoints, and two production dashboards, shipped and iterated over eight months of continuous solo development. The platform runs the full loop — creative generation, campaign launch, performance monitoring, and creator payouts — without requiring the merchant to leave the dashboard.
