I design and evolve a high-performance SaaS Customer Engagement Center (CEC), turning product strategy into resilient, low-latency microservices. I lead architecture, reliability and end-to-end delivery to support global, real-time customer interactions at scale.

• Architected core services that process >1B messages, >30M attendances and >1B automations, ensuring stability under extreme load.
• Led development of the personalization/automation engine, enabling massive, reliable campaign orchestration and richer client engagement.
• Defined modular service boundaries and API contracts to improve scalability, fault isolation and developer velocity.
• Implemented CI/CD (Jenkins) and deployment best practices, increasing release safety and rollback speed.
• Hardened observability and SRE practices with Prometheus, Grafana, Jaeger and Fluentbit, reducing MTTR and accelerating RCA.
• Performed performance tuning and capacity planning across Java/Spring, Kafka, MongoDB, Redis and Kubernetes for low-latency SLAs.
• Mentored engineers, ran architecture reviews and coordinated cross-functional teams to deliver high-impact features.

Led 3 intensive cohorts (2 Java, 1 Web) delivering career-transition training and job-ready skills to diverse learners.

• Trained & mentored 150+ students in Java, HTML, CSS, JavaScript; focused on project-based learning and portfolio delivery.
• Designed inclusive, adaptive curriculum and assessments — ran a special cohort for professionals 50+, improving engagement and completion.
• Translated complex topics into practical exercises, prepared students for technical interviews and real-world development tasks.
• Key skills: Java, Spring, HTML, CSS, JavaScript, mentorship, curriculum design, career coaching, project-based learning.

Built and maintained scalable, secure services for BB Platform, a mission-critical system used by millions. Led architecture, delivery and incident response in a high-complexity, regulated banking environment.

• Delivered critical platform components that improved availability and security for millions of users.
• Optimized performance and stability, reducing production incidents and improving user experience.
• Implemented automated testing, CI/CD and architecture reviews to accelerate releases and lower risk.
• Aligned technical roadmaps with business and regulatory requirements to ensure compliance.
• Led incident resolution and legacy modernization efforts, increasing resilience and peak-load capacity.

Architected and delivered critical systems for CNPq, including an automated financial-batch pipeline for researcher payment cards, replacing manual, error-prone workflows with reliable automation.

• Built end-to-end pipeline using Spring Cloud Data Flow, cutting processing time and eliminating manual steps.
• Improved reliability with retryable, idempotent tasks and detailed observability, reducing incident impact.
• Delivered new features and performance optimizations across CNPq systems, boosting throughput and stability.
• Applied DDD, BDD, and Scrum to align technical solutions with business needs and reduce rework.
• Led containerized deployments and Kubernetes hardening to ensure scalability and secure releases.

Delivered full-stack web systems for public-sector clients (TRE-TO, TRE-AC, TRE-SC) and an international VAT-declaration platform for Angola’s Tax Authority, ensuring security, compliance, and scalability.

• Led architecture and delivery of a budget management system, improving auditability, compliance, and budget cycle speed.
• Developed and integrated electoral and tax systems with secure data handling and reliable reporting.
• Improved maintainability through modular architecture, API design, and coding standards.
• Implemented CI/CD pipelines and automated testing, reducing release risk and deployment time.
• Mentored engineers and ensured accessibility, auditability, and security in production-ready solutions.

Led the Systems Development Team delivering Java EE solutions for the real-estate sector and introduced agile practices to boost delivery speed and software quality.

• Architected and led qImob 2.0 (ERP) from design to production, automating workflows and improving client operations.
• Delivered mobile apps, real-estate platforms, and the qImob Portal, enhancing user experience and efficiency.
• Implemented Scrum/Kanban, code reviews, and automated testing, reducing rework and production defects.
• Mentored developers and standardized technical practices, increasing team alignment and delivery velocity.

During my internship at the Superintendência do Banco do Brasil, I worked with Java EE on internal software development projects. It was a valuable experience where I learned not only technical skills but also how to collaborate in a professional team environment.

I had the opportunity to follow agile practices, participate in project planning, and understand the importance of communication and organization in real development teams. This experience helped shape my foundation in both software development and team collaboration.

Implemented RM ERP modules (Financial, Projects, Contracts, Purchasing, Inventory) and developed custom features in ADVPL for Protheus.

• Led full-cycle ERP implementations, translating business needs into tailored solutions.
• Optimized client workflows, improving financial control and operational efficiency.
• Delivered customizations aligned with client processes while preserving system integrity.
