Principal Solutions Architect | AI-Driven DevSecOps | Cybersecurity & Enterprise Systems

I conceived and built an enterprise AI software development framework using offline LLMs, including Ollama and Qwen, to perform automated security audits, code-quality scanning, and code remediation across multi-language repositories without exposing intellectual property to public clouds.

I designed end-to-end FinTech architecture for E-Cobro and TCash Argentina using .NET C# and Flutter, including payment gateways, digital cash operations, virtual credit cards, crypto trading, Central Bank compliance, and observability through OpenTelemetry and Grafana.

I delivered secure Spring Boot and Liferay backends, GitLab CI/CD pipelines with SonarQube quality gates, penetration testing, load testing, and industrial IoT Android systems integrating OTG/OBD2 vehicular telemetry and real-time GPS routing.

I established and led the in-house IT and Software Engineering division for a long-standing retail chain, managing a team of six engineers and analysts responsible for ERP, POS desktop applications, and infrastructure.

I architected a Java microservices backend using WildFly, Hibernate, and Jersey to support sales tablets, POS cashiers, an e-commerce platform, and proprietary iOS and Android customer applications.

I provided senior mobile and systems consulting across Webmotors, iMonitore/Tecnowise, and STP/Petroplus. At Webmotors, I overhauled a B2B dealership mobile application, resolved legacy defects, completed milestones within 30 days of onboarding, and reduced testing cycles by 80%.

I engineered Android biometric systems using OpenCV facial pattern recognition and .NET REST APIs for driver examination compliance. I also redesigned mobile sales telemetry using Google Fused Location API and offline synchronization, delivering more than 42 structural performance improvements within 60 days.

I delivered mobile solution architecture for consumer applications, including projects for SKY Consumer, Discovery Kids Brasil, and Vagas.com, using Android and Windows platforms.

I authored technical curricula and delivered more than 3,000 hours of specialized instruction in programming logic, Java, C#, and native mobile architecture.

I directed two engineering teams responsible for ERP systems supporting international customs brokerage, bonded-terminal logistics, forward transport management, and financial billing.

I coordinated software delivery across operational and financial systems in a port logistics and customs environment.

I reported to the CTO and managed a team of nine software and architecture specialists.

I implemented a corporate architecture practice, enterprise service bus integrations, and secure coding compliance for enterprise SaaS clients.

I architected Bradesco's digital contract-signing portal and Itaú's enterprise product architecture using .NET Enterprise Library and XML digital signatures for electronic invoicing. I also implemented application-security frameworks aligned with OWASP, DoD, NSA, and NIST guidelines.

I architected security and integration layers for Itaú Bankline retail and corporate platforms and served as lead developer for the Itaú Shopline payment gateway.

I established Secure SDLC training covering cryptography and forensics, represented BankBoston in FEBRABAN PKI and digital-security committees, developed an internal Certificate Authority, and implemented Six Sigma and CMM practices.

I performed information security consulting for major financial institutions, including Unibanco and Orbitall.

My work included ethical hacking, penetration testing, secure code assessments, and information security policy design.
