Understand before building
Strong solutions begin with the problem, the domain, and real-world constraints.
01 Backend software engineer
I build what
makes things work.
I'm Luan Bonifácio. I build backends, APIs, and integrations — with hands-on experience in payments and a keen interest in everything between code and production.

About me
More than a language.
The whole system.
Backend development is my foundation. For nearly five years, I have worked with business systems, REST APIs, databases, webhooks, and external integrations — including real-world Pix flows and a full PSP migration.
I also care about where applications live: containers, Linux servers, Nginx, DNS, SSL, and deployments. I am now growing toward cloud and DevOps while staying grounded in what brought me here: building useful, reliable, and maintainable software.

How I work
Think beyond localhost
Logs, security, deployment, and maintenance are part of engineering too.
Grow with intention
Backend first. Cloud, automation, and distributed systems as the next step.
