Services (six pillars) ### 3.1 IT Consulting Strategic advisory to optimize processes, evaluate stack, and steer technology decisions — from roadmap to operating model. Engagements range from focused architectural reviews to full digital-transformation programs. ### 3.2 Software Development Custom web and mobile systems on modern stacks. From functional scope to production delivery, with documentation and automated tests. We do not ship "minimum viable" without telling you it is minimum viable. ### 3.3 IT Infrastructure Cloud computing, servers, networking, and provisioning. Scalable architecture, monitoring, backups, and operational continuity. Default cloud is AWS; on-premise and hybrid topologies supported when compliance or sovereignty demands them. ### 3.4 IT Outsourcing Specialized professionals allocated to short- or long-term projects with technical management and defined SLAs. Roles include backend, frontend, full-stack, DevOps, security engineering, and data engineering. ### 3.5 Information Security Data protection aligned with LGPD (Lei 13.709/2018), GDPR (Regulation EU 2016/679), and CPRA. Policies, audits, access control, and incident response. We treat security as a build-time discipline, not an audit-time scramble. ### 3.6 Business Intelligence Dashboards, reports, and integrations that turn data into strategic insight. Actionable operational indicators, not just charts. Heterogeneous-source consolidation: SQL, REST APIs, CSV, IoT. --- ## 4.
