Hi! I'm a Full Stack Laravel & Vue/Nuxt Developer specializing in high-performance web applications and AI-driven automation. I combine the stability of the Laravel ecosystem with the speed of modern AI to build "smart" software that doesn't just store data, but actually works for you.
If your project needs:
๐ฅ๏ธ Smart SaaS Applications: End-to-end platforms built with Laravel 11 and Nuxt 4.
โ๏ธ AI Backend Orchestration: Robust Laravel backends that handle LLM calls, streaming responses, and vector embeddings.
๐ฆฟ Automated AI Workflows: Systems that automate content generation, lead scoring, or customer support using OpenAI, Claude, or DeepSeek.
๐ค Intelligent Chatbots & Agents: Custom interfaces for team collaboration or customer self-service with persistent memory.
๐ณ Database & Performance Optimization: Clean MySQL architecture designed for scale and lightning-fast queries.
I bridge the gap between traditional web development and the future of AI. I focus on delivering clean, best-practice solutions that are powerful enough for your business today and flexible enough for tomorrow.
๐ป Tools I use in my work:
๐ Backend: Laravel (10/11), PHP 8.5, RESTful & GraphQL APIs, Sanctum, Passport, Laravel Reverb (Real-time)
๐ Frontend: Vue.js 3, Nuxt 4, Pinia, TypeScript, Tailwind CSS, Nuxt UI

๐ Third-Party: Stripe (Payments), Twilio (SMS), Slack/Discord APIs, Webhooks
The principles I follow in every project:
๐ฆพ Scalable: I utilize modular architecture (Service/Repository patterns) so your app grows as your users do.
๐ Intelligent: I integrate AI natively into your business logic to automate repetitive tasks and reduce overhead.
๐ฆ Reusable: I build Vue/Nuxt components and Laravel packages that are easy to maintain and extend.
๐ผ Best Practices: I strictly follow SOLID principles, PSR standards, and modern testing with PestPHP.
โ๏ธ Sustainability: I design systems for minimal maintenance, with clear documentation and high-level diagrams provided for every solution.
My Top Talents:
โ End-to-End AI-SaaS Development: Building complete, secure products from the ground up.
โ AI-Powered Backend Tasks: Using Laravel queues to handle background AI processing like content tagging or summarization.
โ Performance Tuning: Optimizing slow MySQL queries and Nuxt hydration for a "snappy" user experience.
I donโt just write code; I listen to your vision to ensure the technical solution I build aligns perfectly with your business growth.
