Description

- Architected the backend (FastAPI microservices) and frontend (Next.js / React). - Designed the PostgreSQL schema and migration pipeline. - Integrated Stripe for tiered subscriptions and built all webhook flows. - Orchestrated multiple AI providers (Midjourney, Imagen, OpenAI, custom Stable Diffusion via ComfyUI). - Implemented Figma designs and established CI/CD, observability, and production hosting.

Solutions

- High-performance image pipeline: Composed asynchronous jobs in ComfyUI with Flux-Stable-Diffusion models, added GPU caching, and background queues to slash latency.

- Multi-provider AI orchestration: Wrapped Midjourney, Imagen, and OpenAI behind a LangChain abstraction for dynamic provider selection.

- Subscription & billing layer: Deployed Stripe Checkout and Customer Portal with automated retries, proration, and usage metering; secured events via signed webhooks.

- Secure identity: Adopted Auth0 (PKCE SPA flow) with role-based access control for admins and creators.

- Search & inspiration: Integrated Bing Image Search for reference discovery and Storyblok-powered blog content for prompt-writing tutorials.

- Real-time UX: Added WebSockets plus TanStack Query for live render progress, Tailwind-styled components, and Sharp-based on-the-fly thumbnailing.

- Dev Ops: Dockerized services, set up GitHub Actions CI and Terraform IaC, and instrumented Sentry / Grafana Cloud for monitoring.
