AI-powered software, automation systems, and applications built to streamline real business operations
Many companies grow faster than their internal systems. Processes that once worked manually start becoming inefficient. Teams spend time entering data, responding to repetitive inquiries, or switching between disconnected tools.
I help businesses solve that problem by building AI-powered software, automation systems, and custom applications that connect workflows, automate tasks, and make operations more efficient.
My focus is on AI Voice Agents, AI chatbots, AI software, and AI automation systems that integrate with existing platforms such as CRMs, messaging tools, databases, and internal business systems.

I build AI voice agents and conversational AI systems that automate communication with customers, leads, and internal teams.
Services include:
• AI Voice Agents for inbound and outbound calls
• Conversational AI Chatbots for websites, WhatsApp, and messaging platforms
• Lead qualification and automated customer support systems
• Voice AI integrations using tools like VAPI and Retell AI
• AI agents that integrate with CRMs and internal databases
These systems allow businesses to respond instantly to customers while reducing manual workload.
AI Automation & Workflow Systems
I design and implement AI automation systems that connect tools and automate repetitive tasks.
• Workflow automation using n8n and Make
• Intelligent AI Agents that analyze data and trigger actions
• CRM automation and marketing workflow automation
• AI-driven reporting and operational insights
• End-to-end AI Automations that streamline internal processes
Custom AI Software & Platforms
Beyond automation, I build custom AI-powered software systems tailored to business operations.
• AI Software Development using Node.js and Python
• Custom AI Agentic Solutions for operational workflows
• Integration of OpenAI and Claude LLM models into software platforms
• Backend systems and API integrations
• AI Custom Solutions designed around real business use cases
These platforms help companies centralize their operations and eliminate fragmented systems.
Mobile Application Development
I also build mobile applications that integrate with backend systems and AI-powered services.
• Mobile Application Development for operational tools
• iOS application development and cross-platform solutions
• Field service apps for managing teams, jobs, and workflows
• Apps integrated with automation systems and databases
Real Systems Built for Real Businesses
I have built AI-powered platforms and automation systems for multiple companies including:
• So Special Mobile Mechanic – AI-infused mobile application and operational platform
• Al Arabi Company – dispatch system for operations and maintenance management
• Mystical Agency and Intero Digital – AI automation and proposal generation systems
• AI chatbot and WhatsApp automation systems for clinics and service businesses
These systems typically include AI agents, automation pipelines, mobile apps, dashboards, and backend integrations that help businesses manage operations more efficiently.
Technology & Tools
My systems are typically built using:
• Node.js and Python for backend development
• OpenAI and Claude for LLM-based AI systems
• n8n and Make for workflow automation
• VAPI and Retell AI for voice agents
• API integrations with CRMs, marketing tools, and databases
Ideal Clients
I work best with businesses that need to:
✔ Automate manual processes
✔ Build AI-powered applications or platforms
✔ Integrate systems across multiple tools
✔ Develop custom software or mobile applications
✔ Introduce AI into operations to improve efficiency
Most of my clients are companies whose operations have grown faster than their internal systems — and they need technology that can automate workflows, connect tools, and scale with their business.

I build AI agents, RAG systems, and LLM-powered automation, then wire them directly into production ERP systems. Top Rated Plus, 9+ years engineering experience specializing in AI + ERP/CRM, accounting, inventory, and helpdesk workflows.
Most AI engineers stop at a notebook demo. Most ERP developers can't build AI systems. I do both. I take an AI use case and ship it inside your actual business system, whether that's ERP, another CRM, or any backend, so it runs in production, not a sandbox.
⚡ WHAT I BUILD
🤖 AI Agents & Multi-Agent Systems: LangChain/LlamaIndex-based agents that take actions, not just answer questions. Lead follow-up, ticket triage, approval routing.
🔍 RAG & Knowledge Systems: vector search (FAISS) over live Odoo/CRM data, so answers come from current records instead of stale docs.
📄 AI Document Intelligence: LLM extraction pipelines that read invoices/PDFs and write structured line items directly into Odoo accounting records.
🔌 LLM Integration: OpenAI, Claude, Gemini, and self-hosted open-source models, with provider switching based on cost, privacy, or task requirements.
⚙️ AI + ERP Workflow Automation: LLM-driven decision logic triggering approvals, notifications, and record updates automatically inside ERP.
📈 PROVEN RESULTS
✅ AI invoice processing pipeline: cut manual AP entry time and reduced line-item errors on high-volume vendor bills in Odoo accounting.
✅ AI support agent for Odoo Helpdesk: reduced first-response time and ticket volume by auto-resolving common queries with order/ticket context.
✅ Multi-agent platform (sales + inventory + support): automated handoffs across Odoo ERP operations, one of the more advanced systems I've built.
✅ AI inventory forecasting: analyzed historical Odoo sales/inventory data to predict demand and recommend reorder points.
🛠️ TECH STACK
- AI/LLM: LangChain, LlamaIndex, RAG, AI Agents, Multi-Agent Systems, Vector Databases (FAISS), Embeddings, Prompt Engineering, Fine-Tuning
