Challenges I Faced
Implemented a 'repair-and-retry' resiliency layer with jsonrepair to handle malformed LLM JSON outputs.
Built a custom exponential backoff strategy to manage API rate limits during bulk generation.
Enforced strict type-safety across the stack, ensuring AI output schemas mirror the Prisma database model.
How I Overcame Them
Mastered prompt engineering to direct AI personas and enforce strict schema adherence.
Gained expertise in building robust, error-tolerant backend systems for long-running AI processes.
Leveraged Next.js 16 and Tailwind v4 to implement bleeding-edge frontend standards.
