Senior Solution Architect | Secure Web & Mobile Developer | ISO 27001

Build Secure, Scalable, and Business-Oriented Software. I am a Senior Software Architect and Information Security Expert with a background in leading complex technological projects for global players like Samsung and major financial institutions. Today, I am the Founder & CEO of DIGIKOI, a specialized software house. When you work with me, you get the personalized attention of a senior expert backed by the robust infrastructure and specialized team of my agency. Why partner with me? Most developers simply write code; I build business assets. My background combines deep technical engineering with Governance, Risk, and Compliance (GRC). This means I don't just deliver features; I ensure your product is secure (ISO 27001/GDPR ready), scalable, and built to last. My Core Expertise: Secure Software Development: Web Platforms, Custom Systems, and Mobile Apps (iOS/Android) built with a "Security by Design" mindset. Strategic Leadership: Acting as a Technical Partner or Fractional CTO to guide your digital transformation and architectural decisions. Cybersecurity & Compliance: Expertise in ISO 27001, PCI-DSS, GDPR/LGPD, and Risk Management to protect your IP and user data. What I bring to your project: - Full-cycle development (Design, Code, QA, DevOps). - Professional CI/CD pipelines and version control environments. - A focus on ROI and business impact, not just code. Whether you need to build a platform from scratch, secure an existing application, or scale your tech operations, I bring the maturity and structure necessary for success. Let's discuss how we can turn your complex requirements into an intelligent, secure digital experience.
