[2026] Creating a Developer New Year Fortune Service with AI - AI Does the Development

💬 Are you having these concerns?

"I tried coding with ChatGPT... but is that all there is?" "People say to use AI, but what exactly am I supposed to build with it?" "I want to be recognized as a developer who uses AI well at my company..." "It would normally take a month to build a fortune-telling app, but is it really possible in 2 hours?"

You're not alone.

Most developers only use AI as "a faster copy-paste tool".

• Asking it to write a simple function

• Asking about error messages

• Getting code explanations

As a result, they reach the conclusion "I tried AI but it wasn't that great?"

🎯 In this live session...

In just 2 hours, I'll show you how to truly utilize AI.

1️⃣ Workflow Engineering (Workflow Design)

"From Planning to Design: Using AI as an Architect"

• Before: Asking questions in fragmented functional units, resulting in inconsistent code

• After (System Prompting): Inject the entire project context into the AI.

  • "You are a senior full-stack developer with expertise in infrastructure design."

  • "Based on Next.js (App Router) and Supabase, all infrastructure is automated with Vercel and GitHub Actions."

  • "Before implementing features, finalize the DB schema and API specifications first, then proceed."

• Result: 10x improvement in development productivity. Enables consistent development based on system architecture rather than simple coding.

2️⃣ Ensuring System Stability (Structured Reliability)

"Transform AI outputs into reliable system data"

• Problem: AI's free-form responses can cause runtime errors in programs.

• Solution (Structured Output): Combines AI responses with a strong type system (TypeScript).

  • JSON Schema Enforcement: Configure AI to respond only with defined data structures (schemas), fundamentally preventing data parsing errors.

  • Type-Safe Integration: Match AI-generated data 1:1 with DB schema to ensure stability that won't break even in production environments.

• Effect: Reduces manual validation steps and builds automated data pipelines.

3️⃣ Infrastructure Automation and Deployment (Infra-as-Code & Deployment)

"Accelerate from Infrastructure Setup to CI/CD Implementation with AI"

• IaC Implementation: Design Terraform or Vercel Configuration with AI to build identical development and production environments.

• CI/CD Cycle: Create a GitHub Actions workflow so that the moment you push code, an automated cycle of build → test → deploy happens all at once.

• Result: Infrastructure capable of serving globally is completed in 5 minutes without complex server configuration.

📊 After Deployment: Data-Driven Sustainable Operations (Monitoring)

Deployment is not the end, but the beginning of a new cycle. Monitor real-time metrics and feed them back into the AI workflow.

• Vercel Analytics & Speed Insights

  • Monitor user traffic sources and performance bottlenecks in real-time.

• Supabase Database Health

  • Track DB query performance and API call frequency to optimize infrastructure costs.

• Claude API Usage Monitoring

  • Analyze LLM call costs and token efficiency to use as a basis for improving prompts.

💡 Real-time Dashboard

• "Based on current traffic, DB query response time maintained at 0.8 seconds"

• "User pattern analysis shows API call surge during specific time periods → Infrastructure expansion needed"

• "LLM response accuracy achieved 99%, cost-performance optimization complete"
