• • Designed and implemented centralized technology architecture on local server (Proxmox) for managing multiple points of sale, including Dolibarr ERP/CRM administration to digitize sales, inventory, purchases, and cash flow.

• • Developed AI agents with Python and FastAPI integrated with DeepSeek API for automation of operational processes: automatic generation of production batch tickets, real-time inventory updates, and natural language processing for data recording by operators.

• • Implemented automation of business communications using Evolution API + WhatsApp Business, connected to the ERP for automatic order notifications, inventory alerts, and customer service.

• • Configured secure private networks with WireGuard for remote connection between distributed points of sale.

• • Managed server infrastructure with 24/7 monitoring, automated backup, and high availability, ensuring business operational continuity.

• • Developed high-performance applications with Java 17 and Spring Boot, using asynchronous programming with CompletableFuture and Spring Batch for processing large volumes of data.

• • Implemented messaging with Apache Kafka and distributed caching with Redis for event-driven architectures.

• • Designed and optimized Oracle databases including triggers, stored procedures, and indexes.

• • Managed deployments with Docker and Kubernetes: building manifests and managing images in private registries.

• • Automated CI/CD pipelines with Jenkins integrated with GitLab for continuous delivery to production.

• • Ensured code security through static analysis with Checkmarx and quality with SonarCloud.

• • Developed frontend components with Angular, TypeScript, HTML5, CSS, and Bootstrap.

• • Documented user stories, technical documentation, and ticket handling in production environments.

• • Integration of generative AI in development: use of Claude API, GitHub Copilot, and LLM APIs for code generation and optimization, process automation, and building intelligent features in backend applications.

• Designed and implemented microservices and distributed architectures with Spring Boot, MySQL, MongoDB, and DynamoDB on AWS infrastructure, defining integration contracts between services.

• Managed infrastructure and servers on AWS: RDS, Elastic Load Balancing, API Gateway, Step Functions, Fargate, and Lambda (serverless), governing the design of RESTful APIs exposed through API Gateway.

• Implemented Infrastructure as Code (IaC) with AWS CloudFormation and Terraform for automated provisioning of servers and cloud environments.

• Participated in end-to-end DevOps practices: continuous integration and delivery (CI/CD), adapting environments for microfrontends, continuous scanning, and unit testing.

• Used Amazon SNS for failure notification and CloudWatch/Dynatrace for monitoring critical applications.

• Designed high-availability RESTful and SOAP API contracts (OAS definition, versioning), collaborating with frontend teams on their integration.

• Developed serverless functions with Node.js like AWS Lambda and maintained Angular components in legacy application modernization projects.
