This is a senior, hands-on leadership role requiring 10+ years of experience in building and operating scalable web applications in production environments.

• Oversee frontend integration within a micro-frontend setup (SingleSpa), ensuring seamless performance and UX consistency

• Expert proficiency in PHP (8.x) and Laravel (including Middleware, Queues, Events, Gates/Policies), along with strong experience in Vue.js 3, TypeScript, and modern state management (e.g., Pinia)

• Deep architectural expertise in designing secure, multi-tenant, and distributed systems, with strong understanding of SOLID/DRY principles and long-term maintainability

• Advanced database and performance engineering skills (MySQL/RDS, complex schema design, indexing strategies, Redis caching) in high-traffic environments

• Proven ownership of DevOps-adjacent responsibilities, including Docker-based environments, CI/CD pipelines, semantic versioning, AWS infrastructure awareness, and production monitoring/alerting
