AI in Real Workflows

From Prompting to Agents

Oliver Mazariegos

πŸ‘‹ Before vs After AI

❌ Before

  • Manual coding
  • Debugging alone
  • Slow data exploration
  • Repetitive tasks

βœ… After

  • AI-assisted coding
  • Faster debugging
  • Rapid prototyping
  • Automation mindset

πŸš€ The Shift

I don’t code alone anymore.

I orchestrate AI.

🧠 How I Use AI

πŸ’» Coding Agent

πŸ“Š Data Work

  • SQL/NoSQL generation
  • Data cleaning
  • Analysis

πŸ€– AI Agents

  • Natural language queries
  • Retrieval + LLM
  • Production systems

πŸ’» AI as a Coding Agent

  • Write functions
  • Refactor code
  • Generate tests
  • Debug errors

Think: delegate, not write

⚑ Live Demo

Take messy code β†’ improve it

  • Refactor
  • Add tests
  • Explain logic

⚑ Live Demo

πŸ“Š AI for Data Work

  • Prompt β†’ SQL
  • Prompt β†’ Python
  • Prompt β†’ Insights

⚑ Live Demo

🧬 Real Example

β€œI need a F1 specialist (from zero to functional project)”

β€œI need to improve my code (from existing code to better code)”

πŸ€– AI Agents (Simple View)

User Question β†’ Search β†’ Context β†’ LLM β†’ Answer

πŸ”₯ Why This Matters

  • Works across industries
  • Scales your productivity
  • Reduces repetitive work

πŸ§ͺ Hands-On Exercise

Build Your AI Assistant

🧩 The Problem

You have messy data / task

Your goal: - Extract insights - Automate something

πŸ›  Prompt Framework

  1. Role
  2. Task
  3. Context
  4. Constraints
  5. Output format

❌ Bad Prompt

Analyze this data

βœ… Good Prompt

You are a data analyst. Analyze this dataset and return 3 key insights in bullet points. Focus on trends and anomalies.

πŸ§ͺ Your Turn

  • Pick a task from your field
  • Use the framework
  • Improve your prompt

🧠 Think Like This

How do I delegate this to AI?

βš™οΈ Optional Challenge

Build a Mini Agent

  • Ask questions
  • Refine answers
  • Chain prompts

πŸ’¬ Discussion

  • How would you use this at work?
  • What can you automate?

🧰 Your AI Toolkit

  • ChatGPT - Claude - Gemini - …
  • GitHub Copilot
  • Prompt frameworks
  • Agents mindset

πŸš€ Final Thought

AI won’t replace you.

But people using AI will.

πŸ™Œ Thank You
