At Moder, I build agentic AI automation workflows for enterprise clients using Playwright, Python, FastAPI, React, and AWS services including Lambda, Bedrock, S3, EC2, CloudWatch, and RDS.

At Plusspay, I built and maintained fintech applications supporting 5,000+ monthly transactions. I integrated WhatsApp, Gemini, Binance, and Google Cloud APIs through REST, GraphQL, and WebSockets, bringing generative AI to customer-facing services.

Previously, I delivered scalable Django and Wagtail CMS applications for local customers, taking business and content-focused sites from backend development through deployment.
