What I'm looking for

I'm looking to build production backend, AI, data, and cloud-native platforms where I can own architecture through delivery, improve complex operational workflows, and collaborate across engineering, product, QA, security, and infrastructure teams.

At IBM Consulting, I build cloud-native order management, billing, AI-assisted knowledge, and reporting platforms for healthcare, fintech, and e-commerce clients. I’ve improved high-traffic transaction workflows by 30-40%, introduced Kafka event processing for hundreds of thousands of daily events, and built RAG search systems that reduce operational research from tens of minutes to a few minutes.

I build production services with Python, FastAPI, Django, PostgreSQL, Redis, Kafka, Celery, AWS, Kubernetes, and Terraform, alongside React and TypeScript interfaces that help operations teams manage complex workflows independently.

Previously at Visa and Clevertech, I delivered payment operations, reconciliation, healthcare portal, and reporting systems. I enjoy owning work from architecture through testing, deployment, production support, and mentoring engineers across distributed teams.
