02 / About

I build systems that scale, AI that talks,
and interfaces that handle real load.

Software Engineer with production experience across distributed microservices, multi-tenant SaaS platforms, and real-time AI voice agents. I've built systems integrating Twilio telephony, SAP ERPs, Salesforce, and AI providers including OpenAI, Gemini, Groq, and Claude, shipping Arabic-language voice agents and RAG-powered chatbots for enterprise clients, and migrating high-scale data infrastructure.

Currently at Klenka IT Solutions, building Chameleoni: a multi-tenant recruitment CRM serving hundreds of isolated PostgreSQL databases.
