About Gabriel

I help SMEs, training organizations, and sales teams transition to AI in a practical way: ChatGPT/Claude training, business use cases, AI agent design, and initial operational systems.

My background is from the field: before founding Optia, I spent nearly 5 years in business development and sales management. I saw firsthand what hinders a team: lack of visibility, poorly used tools, repetitive tasks, scattered data, decisions made too late.

Today, I use AI to solve these problems simply and effectively.

I undertake three types of missions:

1. Practical AI Training
ChatGPT, Claude, and Generative AI workshops to help your teams save time on their real tasks: writing, summarizing, research, prospecting, customer support, reporting, meeting preparation, content creation, or training materials.

2. Business AI Agent Design
I help you identify the right use cases, define the agent's operation, write its instructions, structure its knowledge, test its responses, and make it usable in your daily work.

3. No-code / AI Prototyping
When relevant, I build initial simple systems using tools like Claude, ChatGPT, Airtable, Make, n8n, HubSpot, or APIs. The goal is not to pile on tools, but to deliver something that works.

What sets me apart:
- genuine business and sales experience,
- a usage-oriented approach, not a gimmick,
- the ability to train, frame, and build,
- an understanding of SME challenges: time, clarity, adoption, ROI.

I can be involved for short training sessions, an acculturation workshop, AI coaching, or the design of an initial business agent.
