- Translate business and architectural requirements into detailed technical designs and implementation approaches.
- Provide technical direction to developers throughout design, development, testing, implementation, and production support.
- Lead technical-design and code-review sessions and ensure solutions follow established engineering standards.
- Develop complex SQL queries, stored procedures, data-access components, and database integrations. Expertise in Microsoft SQL Server, Oracle Database or PostgreSQL.
- Review and diagnose query-performance problems and perform SQL performance tuning and optimization for scalability, supportability, and maintainability.
- Develop reusable components, frameworks, utilities, and engineering patterns where they can improve consistency and development efficiency.
- Troubleshoot end-to-end application performance issues across the API, application, data-access, and database layers.
- Use GitLab for source-code management and team development workflows.
- Develop, maintain, and continuously improve CI/CD pipelines supporting application build, testing, validation, and deployment processes.
