Rafi Ubaid Putra
Fullstack developer specializing in AI-powered SaaS
New to Contra
Rafi is ready for their next project!
Built a multi-model generative AI platform for text, image, music, and video workflows with a structured orchestration system behind it. IMAGENA uses an orchestrator-worker architecture where a primary model coordinates specialized workers, routes requests
based on context, and executes parallel subtasks when needed.
Combined with RAG pipelines, OCR workflows, vector memory, and Redis-backed system logic, the platform was designed as a scalable fullstack AI product beyond a standard single-model chat experience.

It includes a student dashboard, online exam flow, score tracking, history review, subscriptions, and an admin panel for managing users, subjects, tryouts, and questions. I handled both frontend and backend development using Next.js, React, TypeScript, Tailwind CSS, PostgreSQL, Redis, Drizzle ORM, and Better Auth.
