• Own technical decision-making across the stack, ensuring alignment with long-term architectural strategy.
• Optimize application reliability, security, scalability, and performance across mobile and backend systems.
• Lead refactoring efforts and drive continuous improvement initiatives to enhance code quality and maintainability.
• Guide implementation of responsive user interfaces that support a varied audience, from field technicians on phones to customers on tablets.
• Troubleshoot and resolve complex technical issues across environments.
• Oversee CI/CD pipelines, deployment strategies, and DevOps best practices.
• Evaluate and introduce emerging technologies, tools, and frameworks to improve development efficiency and product quality.
• Participate in Agile development methodologies and help drive estimation, sprint planning, and technical backlog refinement.
• Provide technical input into roadmap planning and long-term product strategy.
• Occasionally travel to well-sites, trade shows, and customer offices to better understand user needs and support solution delivery.
