What I'm looking for

I am seeking a Senior Python/backend role where I can build scalable, reliable cloud-native APIs, optimize performance, and mentor teams in a collaborative, growth-oriented environment.

I am a Senior Python Engineer with over seven years of experience building scalable backend systems, microservices, and cloud-native APIs. I focus on performance, reliability and delivering production-ready systems using Django, FastAPI and Flask.

I have designed microservices and RESTful APIs consumed by millions, improved response times by 40%, and increased backend throughput by 50% through query optimization and caching strategies.

I deploy and automate services on AWS (ECS, Lambda, RDS) and implement CI/CD pipelines, reducing deployment cycles by 70% while maintaining 99.9% uptime. I also build ETL pipelines and integrate ML-ready APIs to support predictive analytics workflows.

I mentor engineering teams on best practices, testing and maintainability, and I seek to bring my backend systems, cloud and API optimization skills to a company focused on reliable, scalable software solutions.
