Backend engineer building SaaS and AI products, including multi-tenant services and LLM workflows.

In my current SeniorBackendAIEngineer contract, I build Node.js and Express services for scalable SaaS applications and AI-powered workflows. I’ve improved API response performance by 30%+ and developed OpenAI and Gemini workflows with routing and fallback logic.

At Adology.AI, I worked on an AI advertising and marketing intelligence platform, improving data-retrieval performance by 24% and developing RAG workflows that kept tenant information separated. Earlier, I built backend features and integrations at CKAN and MuhammadLabsLTD, and I’ve also built projects including an esports platform, an AI photo analysis platform, and a financial analytics platform.
