I help companies build robust, modern web applications. While my career spans 18 years of full-stack evolution, my daily workflow is strictly focused on the speed and elegance of modern Laravel and Vue 3. Why hire me? - Architectural Depth: I’ve been building database-driven apps since before most modern frameworks existed. I write code that lasts. - Laravel Mastery: Advanced Eloquent, Service Patterns, and complex API integrations. - Vue.js Specialist: Expert in state management, component architecture, and high-performance frontends. - Full-Cycle DevOps: I handle the app from the first line of code to the Dockerized deployment on AWS/GCP. Technical Snapshot: - Core: Laravel, Vue.js, Node.js, MySQL. - Tooling: Vite, Tailwind, Docker, Gitlab/Github CI/CD. Specialized Capabilities: - Interactive Mapping: Expert implementation of complex geospatial data using Mapbox GL JS and Google Maps. - Real-Time Connectivity: Building low-latency communication via WebRTC and Sockets. - Digital Transformation: Rescuing and refactoring legacy systems into modern, maintainable Laravel architectures.
