What I'm looking for

I seek senior engineering roles building scalable, cloud-native systems with strong DevOps practices, emphasis on reliability, security, and measurable performance improvements.

I am a senior full-stack engineer with extensive experience designing and delivering scalable, cloud-native systems across fintech, media, and government procurement domains.

I have engineered high-throughput backend services using Java (Spring Boot), Python (Django, FastAPI, Flask), Node.js (Nest.js), and C# (ASP.NET), achieving low latency and high availability in production environments.

I lead projects that integrate distributed data platforms, real-time messaging, and DevOps automation — migrating large datasets, implementing RBAC and OAuth2/JWT security, and automating infrastructure with Terraform, Docker, and Kubernetes.

I focus on measurable outcomes: improving performance, reducing costs with serverless and automation, increasing uptime to 99.99%, and streamlining incident response and monitoring to meet strict SLAs.
