• Hands-on experience with AI-assisted development tools and coding agents (e.g., Cursor, kilo.ai, warp.dev, Claude Code, or similar), with the ability to integrate them effectively into real-world engineering workflows.
• Strong ability to apply AI to real engineering problems, especially in:
• Developer productivity (code generation, testing, documentation)
• Automation of engineering workflows
• Incident analysis and debugging support
• Deep expertise in software architecture, microservices, and cloud-based solutions in AWS.
• Using A.I Agents to build Test-Driven Development (TDD) and behavior-driven testing methodologies, ensuring robust, maintainable code.
• Deep understanding and practical application of Object-Oriented Programming (OOP) principles, including SOLID design, Clean Architecture, and advanced software design patterns.
• Advanced proficiency in Web/API environments, including:
• HTTP protocols
• Designing and consuming RESTful services
• Creating efficient, secure, and high-performance APIs
• Proficiency in database design and optimization (e.g., PostgreSQL, MySQL, or NoSQL databases).
