$ architecture

.NET backend with domain-separated Clean Architecture and an Angular frontend. Issuances processed asynchronously via queues, multi-tenant isolation and Azure deployment with CI/CD pipelines.

! attention points

• ▸High volume of concurrent issuances requiring idempotency and safe reprocessing
• ▸Unstable tax-authority integrations — retries, queues and circuit breakers
• ▸Data isolation between tenants without hurting performance
• ▸Auditing and traceability of every issued document

$ architecture

API standardization across React, Angular, Node, Java and .NET services. DevOps architecture with pipelines, containers and cloud infrastructure management, with technical specs written before implementation.

! attention points

• ▸Heterogeneous stacks and teams requiring common standards
• ▸Integrating legacy systems without disrupting operations
• ▸Observability and traceability across services
• ▸Cost predictability on cloud infrastructure

$ architecture

React frontend consuming Node and Java APIs, legacy module refactoring, component standardization and continuous delivery via pipelines.

! attention points

• ▸Performance under heavy user load
• ▸Legacy refactoring without introducing regressions
• ▸Constant alignment between frontend and backend teams

$ architecture

React and React Native applications integrated with Node services, with user controls and C#/Java library integrations with Genexus, plus requirements analysis and technical planning.

! attention points

• ▸Integrating native C#/Java libraries with Genexus
• ▸A shared common base across web and mobile
• ▸Evolving requirements with constant validation
