Software development with security.
I specialize in mobile software development focused on security and fraud prevention. I build complete mobile, web and backend applications, as well as anti-fraud SDKs, and provide technical consulting.
Services
Development and consulting
Complete application and SDK projects, or consulting for the software your team already develops.
Development
Complete applications
I develop web, mobile and backend applications, from planning to release. I also modernize existing systems and migrate legacy code to newer technologies.
Possible scope: Complete applications
- Interface, business logic and APIs
- Testing, documentation and production preparation
Anti-fraud SDKs
I build SDKs that identify device risk signals and support fraud prevention decisions. The project can include integration with the fraud prevention services already used by your company.
Possible scope: Anti-fraud SDKs
- Tampering detection and device signal collection
- iOS and Android distribution, versioning and integration guide
Consulting
Software architecture
I help your team address maintenance, integration and scaling problems. I also support the planning and implementation of legacy code migrations to newer technologies.
Possible scope: Software architecture
- Architecture assessment, modularization and technical standards
- Incremental migration roadmap and technical guidance for your team
Digital channel security
I assess risks in your apps, websites and APIs and work with your team to fix the most critical issues.
Possible scope: Digital channel security
- Authentication, session and sensitive flow review
- Threat modeling and remediation priorities
SDK integration and evolution
I review in-house or third-party SDKs to simplify integration and reduce performance, compatibility and maintenance problems.
Possible scope: SDK integration and evolution
- API, dependency and app impact assessment
- Guidance on distribution, updates and documentation
Technical improvements for LGPD compliance
I review how the application handles personal data and recommend software changes to improve compliance with Brazil’s LGPD.
Possible scope: Technical improvements for LGPD compliance
- Mapping of data collection, storage and access
- Data minimization, retention and protection recommendations
Scope and deliverables are agreed in the proposal based on the project’s needs.
About me
