What I'm looking for

I'm looking for remote backend or full-stack work where I can build AI platforms, enterprise software, high-load systems, and secure production infrastructure.

I've built secure AI transcription and voice automation products at Secreton, rewriting Flask into asynchronous FastAPI microservices with RabbitMQ and delivering blue-green deployments in under two minutes. I also built the Svelte and Astro frontend, integrated payments, and implemented workload-based GPU provisioning to eliminate idle GPU costs.

At Marketplace Trading Center LLC, I led a two-developer team and built an Asterisk outbound platform handling 12,000 calls per hour, reducing lead-generation costs by 45%. I also developed CRM, warehouse automation, marketplace integrations, self-hosted VPN infrastructure, and secure systems across Python, Java, Rust, PostgreSQL, Linux, and CI/CD.
