- Architect and develop APIs, services, and microservices with REST and/or GraphQL.
- Build and manage CI/CD pipelines and ensure DevOps best practices are followed.
- Lead code reviews, mentor team members, and foster a culture of engineering excellence.
- Collaborate with cross-functional teams to drive product innovation and improve UX/UI.
- Identify performance bottlenecks, security vulnerabilities, and scalability issues.
- Champion test-driven development (TDD), code quality, and maintainable codebases.
- Stay current with industry trends and contribute to technology roadmaps.

- Solid understanding of containerization (Docker) and orchestration (Kubernetes).
- Familiarity with security best practices, performance optimization, and scalability.
- Excellent communication skills and a proactive mindset.
