• Evolve LeadExpert - build new features, enhance existing modules, and safeguard overall system performance.
• Bug-fixing & continuous improvement - resolve "small" issues efficiently, identify root causes, and implement lasting structural fixes.
• Backend & frontend development - PHP/MySQL on the server side; HTML, CSS, and JavaScript (jQuery) on the client side.
• Integrations & automation - handle API integrations, webhooks, cron jobs, and queues with clear logging and monitoring.
• Structure & follow-through - manage tasks via tickets/boards, maintain clear documentation, and deliver predictable, high-quality releases.
• Explore AI opportunities - contribute ideas and code for practical AI applications within our workflows and in LeadExpert.
