Portfolio/// no fluff, real work

I do marketing, branding and advertising, combined with AI systems.

01 — About me

I help companies with communication, marketing and brand — and I use AI to execute it at another scale.

My base is communication, marketing, branding and advertising: I understand strategy and how to grow a brand. AI comes after — it's the tool I use to execute all of that faster and at greater scale, without losing the human judgment where it matters. Idea and strategy first; then AI to take it further.

How I work

I don't just use AI — I build the systems that make it useful.

I come from communication, marketing, commerce and advertising: I understand strategy, and I've studied how to keep a company running and grow it. Before I touch anything, I learn its situation, its needs and its goals, and I use that to build the base the AI will work on. I don't let it write the strategy or do the research for me — I find that pointless, almost foolish, and I won't have it: the moment you hand it everything, it's the one running you. You have to be at its level and work with it to stretch your own abilities and get the most out of them. From there I build large pipelines where I decide which tool comes in at each step, encode the brand once, and let the system run. When AI gets it wrong, it's almost always because you're not at its level — so I work every detail and place human checks exactly where they matter, checks that make it more autonomous over time. I keep a person on whatever has to feel human and automate the rest, with one goal: more efficiency, less wasted time.

01

Briefing

AI doesn't write the brief — it writes around it, faster than you can read. I analyze the company, build a real base, and generate from there.

02

Prompting

I encode the strategy into its parts — voice, brand, mission, values… — get it all ordered, and with that base I start the pipelines.

03

Pipelines

I wire Claude, image/video models and my own MCP tools into a repeatable flow — brief in, on-brand assets out.

04

Evals

Nothing ships without passing the filter: every piece is checked against a checklist, and if it smells like AI, it doesn't go out. I'd rather lose a day than publish something that looks fake.

05

Handoff

I deliver communication and AI systems built for the company: I bring the AI of the moment to the real need they have right now, ready for the team to use.
