What I'm looking for

I'm seeking senior backend roles where I own Python API design-to-deployment, optimize async systems, and work with cloud (AWS/Terraform). I value collaborative teams, high SLAs, and opportunities for technical growth.

I am an experienced backend engineer with over 4.5 years working with Python, focused on performance, scalability, and clean architecture. I take ownership from initial design to deployment and long-term support, specializing in asynchronous processing and cloud infrastructure.

I scaled backend infrastructure across six AI-driven platforms, led async Celery pipelines reducing task lag by 50%, and managed AWS deployments via Terraform to meet high SLAs. I built and deployed LLM-based APIs with FastAPI, designed billing and multi-tenant APIs, and mentored junior developers while maintaining production-ready services.
