  • Technical Leadership & Mentorship: Conduct rigorous peer code reviews, enforce coding standards and security best practices, and actively promote best practices amongst the team.
  • DevOps & Release Management: Drive modern Application Lifecycle Management using Git, Salesforce DX (SFDX), and CI/CD deployment pipelines across multi-tier sandbox topologies.
  • Solution Strategy: Evaluate client requirements to balance declarative (“clicks”) and programmatic (“code”) approaches, ensuring solutions are performant, maintainable, and aligned with standard platform capabilities.
  • Client Engagement: Participate in client workshops, technical discovery sessions, and solution demos, translating complex technical concepts into clear business language for stakeholders.
