• Communicate technical concepts clearly to non-technical stakeholders, fostering alignment and understanding.
• Identify opportunities to modernize legacy systems and improve overall application performance and maintainability.
• Research and recommend emerging technologies that can enhance development efficiency and user experience.
• Champion a DevOps culture and advocate for automation, monitoring, and proactive application management.

Technical Leadership & Hands-On Development

• Lead design and development of custom web and enterprise applications, including both front‑end and back‑end components.
• Write clean, maintainable, and efficient code using modern technologies and frameworks (e.g., specific tech skills we are looking for)
• Provide technical mentorship and code reviews to other developers, promoting continuous learning and adherence to standards.
• Drive solution design sessions, reviewing architecture and ensuring that implementations meet design and performance requirements.
• Lead troubleshooting and root analysis for complex system issues.
