Senior Laravel Developer | SaaS, APIs, PostgreSQL, AWS & Vue.js

Senior Laravel developer with 10+ years of experience building, scaling, upgrading, and maintaining SaaS platforms, marketplaces, REST APIs, and complex business applications. I specialize in Laravel, PHP, PostgreSQL/MySQL, Redis, Docker, AWS, REST APIs, Vue.js, performance optimization, third-party integrations, and modernization of existing applications. How I can help you: • Build and extend Laravel SaaS applications • Take over and improve existing Laravel projects • Develop REST APIs, webhooks, and third-party integrations • Upgrade legacy Laravel/PHP applications to modern versions • Diagnose and fix complex backend bugs • Optimize PostgreSQL/MySQL queries and application performance • Implement Redis caching, queues, and background processing • Build Vue.js dashboards, admin panels, and business interfaces • Deploy Laravel applications using Docker, AWS, Nginx, and CI/CD • Improve application architecture, automated testing, and production reliability Existing Laravel Applications A large part of my work involves joining existing projects and quickly understanding complex codebases. I can help stabilize an application, fix long-standing issues, add new functionality, improve architecture and performance, or modernize an older Laravel system without rebuilding everything from scratch. SaaS & Business Applications I have experience working on SaaS platforms, marketplaces, ERP and retail integrations, analytics and reporting systems, multi-role admin panels, notification systems, search, payment and authentication flows, and applications with complex business logic. APIs & Integrations I build and maintain REST APIs and integrate Laravel applications with third-party services including AWS, Google services, OAuth providers, payment systems, webhooks, email services, and external business systems. Databases & Performance I work extensively with PostgreSQL and MySQL, including database design, migrations, indexing, query optimization, debugging slow queries, and improving application performance with Redis, caching, queues, and background jobs. Production & Infrastructure My production experience includes Docker, AWS, Nginx, Redis, PostgreSQL/MySQL, Laravel queues and workers, CI/CD pipelines, automated testing, monitoring, and troubleshooting production environments. Core technologies: Laravel • PHP • PostgreSQL • MySQL • Redis • REST API • Vue.js • JavaScript/TypeScript • Docker • AWS • Nginx • Git • PHPUnit • CI/CD I focus on maintainable solutions rather than quick patches. If you have an existing Laravel application that needs an experienced developer to fix problems, add features, improve performance, integrate external services, or prepare it for production, I'd be happy to discuss your project.
