📋 Description

• Leadership and Mentoring: Provide technical leadership to the engineering team by reviewing solutions, guiding developers, and promoting software design best practices. • Architectural Modernization: Drive the evolution of monolithic systems to microservices, assessing trade-offs between refactoring, rewriting, and decoupling systems. • Integration Bridges: Enable interoperability of complex systems via REST APIs, legacy SOAP services, and high-performance messaging. • Operational Reliability and Quality: Investigate technical bottlenecks, contribute to resolving production incidents, and support the definition of code quality standards. • Cross-functional Alignment: Translate complex technical decisions for diverse audiences and lead strategic alignments with Architecture, Security, Infrastructure, and Product teams.
