We are seeking a high-caliber Senior Full-Stack Developer to lead the comprehensive rebuild of a production system. This project involves migrating and optimizing a platform with deep third-party API integrations. The ideal candidate is a "polyglot" engineer—equally comfortable architecting Laravel backends as they are building high-performance UIs in Next.js or Vue.js, all while maintaining a secure, high-availability AWS environment. Technical Requirements: Backend Expertise: Mastery of Node.js (MERN/MEAN stacks) and PHP (Laravel). You should be able to architect RESTful APIs, manage complex database schemas (MongoDB/MySQL), and handle server-side logic with precision. Frontend Proficiency: Extensive experience with Next.js (SSR/SSG) and Vue.js. You understand component-based architecture, state management, and building responsive, SEO-friendly interfaces. AWS & DevOps: Proven experience in AWS VPC configuration, including subnets, security groups, and NAT gateways. You must be skilled in resource optimization (caching, load balancing, and instance right-sizing). API Integration: Expert-level skill in integrating, securing, and troubleshooting complex third-party APIs. Troubleshooting: An "outstanding" debugger. You can trace issues across the entire stack, from frontend state to server logs and network bottlenecks.
