Senior Full-Stack PHP Laravel Developer with 5+ years of experience building production-grade REST APIs, SaaS platforms, and multi-tenant systems across healthcare ERP, fintech, sports streaming, and e-commerce domains.
The most significant system I've engineered is a multi-tenant omnichannel healthcare communication ERP for Turkish healthcare clinics — handling 1M+ active chat rooms and 20M+ messages, integrating WhatsApp Business, Facebook Messenger, Instagram DM, Twilio SMS/voice, and OpenAI translation APIs into a single SPA dashboard. I architected the backend communication layer, implemented a custom multi-tenant authentication system to securely isolate clinic data and webhooks, built Laravel Queue workflows with custom pause/resume state mechanics for bulk imports, optimized critical MySQL queries from timeouts down to seconds using temporary tables and Redis caching, and managed AWS S3 storage across all tenants.
At Ventie 30 (Italy, Remote), I architected a multi-module sports ERP for the World Baseball Softball Confederation (WBSC) — with multilingual support, a Google Sheets API integration engine for dynamic permission and form field mapping, and high-performance RESTful APIs with async AJAX workflows.
At AppCrates, I contributed to a live sports streaming platform for football clubs, a sports podcast network (Sport-Social) with automated ingestion and per-user tracking, a Stripe-powered social commerce platform (Bell3) with WebSockets and Docker, and a multi-role marketplace (Caspers) with Firebase and full mobile APIs.
What I bring to a team:
→ Laravel architecture — Service, Repository, DTO, Action, Policy patterns
→ RESTful APIs with Sanctum, JWT, OAuth, Apple Sign-In, RBAC
→ Real-time systems — WebSockets, Pusher, Socket.io, Firebase
→ Multi-tenant SaaS with isolated data, webhooks, and traffic routing
→ Integrations: Twilio, Meta APIs, Stripe, Zoho CRM, OpenAI, AWS S3, Google Sheets API
→ MySQL, PostgreSQL, Redis — query optimization, composite indexing, N+1 elimination
→ PHPUnit, PHPStan Level 6, Laravel Pint, GitHub Actions CI/CD, Docker
→ Full-stack development — Vue.js 3, Composition API, Pinia, Vue Router, Inertia.js, JavaScript, jQuery, Axios
→ Agile remote collaboration — Git, GitHub, Jira, Bitbucket
