What I'm looking for

I seek a role focused on scalable backend systems and DevOps, where I can lead engineering initiatives, optimize performance, and build reliable, cost-efficient cloud platforms.

I am a Senior Software Engineer with 10 years of experience building scalable backend systems using Python, Django, Flask and cloud-native architectures. I lead architectural design, performance optimization and CI/CD automation, and have reduced latency and infrastructure costs while improving testing coverage and reliability.

I have managed small engineering teams, introduced DevOps practices with Terraform and AWS, and contributed to high-scale SaaS platforms used by thousands of users. I am keenly interested in DevOps and Golang and consistently deliver measurable improvements in throughput, deployment speed, and system cost.
