AI Integrations Expert | Laravel Multi-Tenant SaaS Architect

Job Success
Ampara, Sri Lanka - 8:28 pm local time
With a decade of full-stack engineering experience, I build enterprise-grade web applications that combine robust, secure backends with modern artificial intelligence. I don't just write code; I architect solutions that automate workflows, reduce overhead, and scale seamlessly as your user base grows.
Whether you are launching a micro-SaaS, integrating a low-latency AI voice concierge for automated bookings, or building complex document processing tools, I deliver clean, testable, and production-ready applications.
WHAT I CAN BUILD FOR YOU:
Multi-Tenant SaaS Platforms: Secure, single-database scoping via global Eloquent scopes and isolated repository patterns.
AI Voice Agents & Telephony: Low-latency conversational agents for reservations and customer support using Vapi, Twilio, and Retell AI.
AI-Driven Document Processing: Intelligent analyzers and OCR tools capable of extracting and structuring data using vision models, OpenAI, or Gemini.
High-Performance Web Portals: Lightning-fast directories, interactive mapping integrations, and dynamic dashboards.
MY TECHNICAL ARSENAL:
Backend & API Architecture: PHP (Laravel 11/12), Python (FastAPI), Node.js.
Artificial Intelligence: OpenAI, Llama 3, Groq, EasyOCR, RAG pipelines, and custom prompt engineering.
Modern Frontends: Vue.js, React, Angular, Alpine.js, and Tailwind CSS.
Infrastructure & Database: Docker, MySQL (advanced indexing & query tuning), Redis, AWS.
Workflow Automation: GoHighLevel syncs and custom webhook endpoints.
WHY WORK WITH ME?
I specialize in the intersection where traditional software architecture meets the new wave of AI. You get a developer who understands modern frontend ecosystems, deep backend optimization, and the strict security requirements of tenant-scoped data.
