About
01Full stack developer with a strong backend focus, working on mission-critical SaaS platforms where performance, stability, security and data integrity are essential. My core stack is PHP, Laravel, TypeScript, Node.js and REST APIs — building scalable, resilient and secure solutions.
Security is my edge: I hold a Lato Sensu specialization in Cybersecurity and design with secure SDLC, software architecture, governance and risk management in mind — not as an afterthought.
I work across relational and NoSQL databases (MySQL, PostgreSQL, MongoDB, DynamoDB) plus Redis, and in cloud-native environments with AWS, Kubernetes and CI/CD. I'm also drawn to AI, automation and developer productivity — using technology to create real business value.
What I offer as a professional
02Backend-first full stack engineering, with application security as a differentiator. Here's where I create the most value — and the full toolset behind it.
Node.js & TypeScript
Type-safe services and modern JS/TS tooling, alongside a frontend with Vue & React.
Application Security
Secure-by-design with OWASP practices, authentication/MFA, LGPD and governance — backed by a Lato Sensu specialization in Cybersecurity.
Cloud & DevOps
AWS, Kubernetes, Docker and CI/CD pipelines for reliable, observable, production-ready systems.

02
Multifactor · 2023 Personal
Multi-factor authentication implementation in TypeScript — adding a strong second security layer to user sign-in.
03
Partner Integrations At work
High-criticality integrations on mission-critical SaaS — secure REST APIs and microservices connecting partners such as Conciliadora, PJBank, eNotas and Alterdata.
