AI Fullstack Developer | Laravel Multi-Tenant SaaS Architect
100% Job Success
4.6  (8 reviews)
Ampara, Sri Lanka - 3:39 am local time
Need a scalable, multi-tenant SaaS platform integrated with advanced AI features? I build enterprise-grade web applications that combine robust Laravel backends with modern AI capabilities.

I specialize in the intersection of Full-Stack Development and Artificial Intelligence—building secure, tenant-scoped SaaS architectures and integrating them with LLMs, Voice Agents, and OCR tools.

---
EXPERTISE IN AI & SAAS ARCHITECTURE:
---
1. MULTI-TENANT SAAS & BACKEND
* Multi-Tenancy Scoping: Single-database scoping via global Eloquent scopes.
* Repository Pattern: Isolating database logic for clean, testable, and scalable code.
* Enterprise APIs: Developing secure RESTful APIs and webhook endpoints.
* Database Tuning: Advanced MySQL indexing, performance optimization, and query tuning.

2. AI INTEGRATIONS (Web & Voice)
* AI Voice Agents: Low-latency voice assistants using Vapi, Twilio, and Retell AI.
* AI-Based OCR: Extracting data from documents and images using vision models.
* LLM Features: Function calling, RAG (Retrieval-Augmented Generation), and custom prompts.
* Automation: Syncing web apps with GoHighLevel workflows.

3. MODERN FRONTENDS
* Laravel Blade + Alpine.js + Tailwind (for fast, lightweight, and low-data frontends).
* React, Next.js, and Vue.js (for dynamic, single-page application interfaces).

---
CORE TECH STACK:
---
* Backend: PHP (Laravel 10/11), Python (FastAPI), Node.js.
* AI / Telephony: Vapi, Twilio, Groq, Llama 3, OpenAI, EasyOCR.
* Frontend: Vue.js, React, Next.js, Angular, Alpine.js, Tailwind CSS.
* Infrastructure: Docker, MySQL, Redis, AWS.

If you want to build a secure SaaS platform with cutting-edge AI features, let's connect and discuss your architecture.
