What I'm looking for

I seek roles where I can build production AI-enabled backend systems, mentor engineers, and drive scalable, secure cloud-native solutions with strong observability and continuous improvement.

I am a Senior Python Backend Engineer and AI/ML practitioner with 10+ years building scalable, high-reliability backend systems and AI-enabled products for healthcare and logistics. I specialize in Python (Django, FastAPI), microservices, distributed systems, and cloud delivery on AWS and Azure, and I have production experience delivering NLP and LLM/RAG features with evaluation, monitoring, and safety guardrails.

I have led teams and projects deploying ML pipelines, entity extraction, embeddings and vector search, drift monitoring, and secure APIs across Kubernetes and serverless platforms. My measurable impacts include large-lift performance and availability improvements, optimized database performance, reliable event processing with Kafka, and mentoring engineers on testing, observability, and AI integration.
