What We Do
From the first technical decision to production, we cover the full lifecycle of your product.
Tailored systems built around your business rules — reliable, maintainable, and designed to scale with your operation.
Modern, fast, and responsive web platforms and mobile apps — from marketing sites to complex products with real users.
CI/CD pipelines, cloud architecture, containers, and observability — infrastructure that deploys confidently and stays up.
Senior guidance on system design, technology choices, code reviews, and technical due diligence before you invest.
Have an idea but no technical team? We scope, plan, and build a focused first version that validates your product fast.
Extend your team with senior engineers who integrate into your workflow — your process, your repos, our tooling.
Who We Are
MARTUZZI TECH was founded by João Martins and Rafael Bertuzzi — software engineers with deep backgrounds in product development, cloud infrastructure, and mobile, who have delivered software for companies in Brazil and around the world.
Co-Founder · Full-Stack & Cloud Engineer
Software engineer with 8+ years of experience delivering digital products and consulting projects for companies in Brazil and abroad. Works across web applications, backend systems, cloud infrastructure, and complex integrations, with a focus on building scalable technology that solves real business problems.
Co-Founder · Frontend & Mobile Engineer
Software engineer with 7+ years of experience building web and mobile products for companies in Brazil and international markets. Specialized in modern frontend architecture, React, React Native, and TypeScript, with a strong focus on product quality, maintainability, and creating polished digital experiences.
The Model
Traditional consultancies price by the head: a rate card per seniority level, a change order when the work needs a different skill, and account managers in between. We work the other way round. One flat monthly rate gives you the whole team — whichever discipline your product needs that month.
AI-accelerated delivery means more shipped every month — at the same flat rate.
AI, Handled
Bringing in an outside team usually means provisioning seats, sharing API keys, and adding other people's tooling to your billing. Not here. Our engineers arrive with their own enterprise AI tooling — licensed, paid for, and configured by us.
Our AI tooling is licensed under our account. It never appears on your invoice, and you are not asked to provision anything for us.
We never ask for your API credentials or provider accounts — so there is nothing of yours to rotate, audit, or revoke when the engagement ends.
We work on enterprise tiers configured so your code is not retained or used for training. Your IP stays yours, and we sign your NDA before we see a repository.
AI makes us faster, so a small senior team delivers the output of a much larger one. Your flat monthly rate does not move because of it.
How We Work
A call with both founders to understand your goals, constraints, and technical landscape.
A clear scope, architecture plan, timeline, and one flat monthly rate — no surprises.
Iterative development with regular demos and direct access to the engineers doing the work.
Deployment to production, monitoring, and ongoing support as your product grows.
Tell us about your project — a product built from scratch, or senior engineers to strengthen your team. The first conversation is free, and it is with an engineer, not a salesperson.
We reply to every enquiry within one business day.
