Android Engineer
About Me
I am a Software Engineer with strong experience building Android applications, scalable systems, and high-criticality digital products across technology companies, startups, and major financial institutions.
I have worked extensively with native Android development, Kotlin, Java, software architecture, systems integration, performance, security, scalability, and product evolution, with a consistent focus on delivering robust and sustainable solutions.
My career began with web projects and enterprise systems, where I contributed to portals, e-commerce platforms, campaign platforms, gamification, ERP, BI, inventory, and integrated services for well-known brands.
I later expanded into startup and international product work, helping drive the digital transformation of the equipment rental market in Brazil and contributing to Android products for heavy equipment management and machinery rental.
A major part of my background is in the financial sector, where I worked on mission-critical solutions for payments, financial transactions, digital banking services, reliability, security, and user experience.
I am a hands-on engineer with strong technical ownership and the ability to move across architecture, development, and product vision. I enjoy building solutions that create real business impact and support long-term product sustainability.
