What I'm looking for

I seek senior backend or cloud roles where I can design scalable microservices, lead teams, improve CI/CD and observability, and integrate ML or blockchain solutions.

I am a Senior Python Engineer with 15+ years designing and developing scalable microservices and distributed systems using Django, Flask, and FastAPI. I build resilient REST and gRPC APIs, event-driven architectures with Kafka and Pub/Sub, and migrate monoliths to microservices using DDD and Clean Architecture while ensuring secure, compliant systems.

I have extensive cloud-native experience on AWS and GCP, automated infrastructure with Terraform and Ansible, containerized and orchestrated workloads with Docker and Kubernetes, and integrated ML and blockchain solutions. I lead Agile teams, mentor engineers, drive CI/CD and observability best practices, and focus on performance optimization and secure data handling.
