What I'm looking for

I seek senior engineering roles building scalable backend and ML/AI systems in cloud-native teams with strong DevOps, mentorship, and impact opportunities.

I am a Senior Python developer with 11+ years designing and delivering scalable, high-performance enterprise applications across cloud-native and distributed environments. I build robust backend systems and RESTful APIs using Django, Flask and FastAPI, and architect microservices deployed on Kubernetes and AWS.

I have extensive experience in data processing, ML/AI and NLP—designing, training and deploying models with TensorFlow, PyTorch, Hugging Face, and LLM/RAG pipelines, and operationalizing them with PySpark, Airflow and SageMaker. I also develop responsive front ends with React and TypeScript to surface model insights and user-facing features.

I champion DevOps practices, CI/CD, observability and performance optimization (Terraform, Docker, Jenkins, CloudWatch, ELK), mentor teams in Agile/Scrum settings, and drive architectural and testing improvements that measurably increase reliability and performance.
