Marcos LeiteThe Full Stack Marketeer.
Brand strategy, product design, and the growth systems that sell them - under one roof. 13 years turning ideas into shipped, selling products.
About
Since 2013, I've worked the full stack of marketing - from hand-built brand identities to injection-molded product design to the campaigns that move them off the shelf. I approach every brand as one system: the object, the packaging, the page, and the campaign all have to agree with each other.
I plan the strategy and execute the campaign - the two rarely sit in different hands.
Positioning, creative direction, and identity systems - from first concept to signed guidelines.
Technical SEO, landing pages, conversion funnels, and the lifecycle email that turn attention into revenue.
Software built and shipped in-house with Claude and AI coding agents - scoped to the job, not licensed off the shelf.
"Never surrender. Every problem has a solution - you just haven't found the right angle yet."

Full Stack Architecture
Everything I'm able to cover, mapped like a codebase - one system, not five separate hires.
Brand, product, and growth usually sit in three separate hires who don't talk to each other. I run all three as one system - so nothing gets lost in the handoff, and you're not paying the coordination tax between departments.
Impact
The measurable side of building brand, product, and internal tools in-house.
Communication & sales output growth from the right platforms and AI agents
Less repetitive work across 6 automated department workflows
Saved in setup cost across the PIM, DAM, Ticketing, SAT & SRM suite
Saved every year versus buying a SaaS equivalent
AI Toolkit
Full-stack marketing now means full-stack AI fluency - the models and tools built into how I work. The real shift isn't which platform I use, it's that I build my own: Claude and AI coding agents as the engineering team, instead of a SaaS vendor.
