Matheus Mendes

Software Engineer

I solve business problems with software. I start by understanding the problem, then pick the right solution and technology for it — from interfaces and integrations to performance and technical SEO — and ship products that are fast, easy to maintain and built to evolve.

What I solve

Services

Custom products

Software built around your business — not a generic template with your logo on it.

Architecture, components and content management designed around what you need, with the right technology for the job.

E-commerce

An online store that works beyond the checkout page.

Catalog, payments, integrations and a back office your team can actually manage.

Design → code

Have a design? I'll turn it into a real, responsive, maintainable product.

Faithful implementation, reusable components and real responsiveness.

Performance

Slow website? Let's find and fix the actual cause.

Diagnosis, asset and caching optimization, code improvements and Core Web Vitals.

Ongoing evolution

Someone to keep your product working and evolving after launch.

Updates, fixes, improvements and ongoing technical support.
