What I'm looking for

I seek roles where I can design cloud-native, scalable systems, lead engineering teams, integrate AI into production, and drive DevOps best practices in a collaborative, growth-oriented company.

I am a Senior Systems Engineer and Software Developer with 15+ years delivering high-performance software across fintech, manufacturing, government, and education sectors.

I architect and implement full-stack solutions using Java, Python, C++, and C#, and design cloud-native platforms on AWS and Azure with Terraform, Docker, and Kubernetes.

I have led migrations, modernized legacy systems, and integrated AI models (PyTorch, TensorFlow) into production, achieving measurable improvements in cost, performance, and availability.

I mentor teams, drive DevOps and CI/CD practices, and bring deep domain knowledge in trading systems and FIX Protocol to build secure, low-latency platforms.
