I architect compliant agentic AI and FinTech platforms for enterprise transformation.

I've led solution architecture for digital banking, loyalty, HR, analytics, and FinTech programmes at Etisalat (e&), serving millions of users in highly regulated environments. I translate ambiguous business challenges into compliant platforms spanning mobile, web, backend, data, cloud, and enterprise integrations.

At PBC Systems & Solutions, I designed agentic AI workflows, LLM and RAG solutions, AI-driven analytics, and lakehouse data pipelines for FinTech and enterprise clients. My work has reduced deployment cycle times by 30%, unauthorised-access incidents by 40%, and improved transaction success rates by 20%.

Across 17+ years, I've built predictive churn and forecasting models, secure payment and banking integrations, conversational chat-with-data experiences, and scalable microservices. I work hands-on with Azure AI Foundry, OpenAI APIs, LangChain, Hugging Face, Python, cloud-native architecture, and governance frameworks that balance innovation with security and regulatory requirements.
