- Thorough knowledge of secure application development, OWASP Top 10 vulnerabilities, DevSecOps practices, CI/CD concepts, testing practices, responsible AI-assisted development practices, and approved technology standards.
- Knowledge of translating legacy business rules, workflows, data dependencies, and domain concepts into modern technical requirements, domain models, and implementation designs.
- Strong skill in reading, reverse-engineering, documenting, and assessing undocumented legacy application structures, data flows, business rules, domain boundaries, and tightly coupled code paths.
- Strong skill in applying domain-driven design concepts to refactor and rewrite legacy business logic into modular, maintainable, secure, AI-ready, and cloud-ready application components and services.
- Strong skill in troubleshooting application defects, integration issues, performance constraints, runtime environments, and service-to-service communication errors.
- Skill in using AI-assisted engineering tools responsibly to accelerate code understanding, pattern identification, documentation, modernization planning, and developer productivity while validating outputs for accuracy, security, and compliance.
- Ability to develop modernization blueprints, domain models, technical documentation, architecture mappings, and implementation guidance that describe how legacy systems will transition to modern platforms.
- Ability to translate legacy business processes, system behavior, and domain concepts into clear technical requirements, design options, integration patterns, modernization work items, and services aligned to business capabilities.
- Ability to collaborate with architects, engineers, security, cloud, data, AI, vendor, and program teams; provide technical guidance; and support modernization decisions during planning and implementation.
