What I'm looking for

I’m looking for a senior individual-contributor role in a mature engineering team, focused on Linux and platform infrastructure, CI/CD, observability, and AI systems. I value clear ownership, documented operations, sustainable on-call practices, and opportunities to deepen my hands-on Kubernetes, cloud, and Infrastructure as Code experience.

I am a Senior DevOps and Platform Engineer with extensive production experience in Linux infrastructure, CI/CD automation, enterprise systems, databases, distributed platforms, observability, networking, and incident troubleshooting.

In my current role, I support infrastructure and deployment automation for 30+ services across 10 test and 12+ production customer environments. I build and maintain CI/CD using Jenkins, GitLab CI/CD, Azure Pipelines, and Ansible.

My production experience includes Oracle, PostgreSQL, Kafka, Cassandra, Keycloak, Prometheus, Grafana, OpenTelemetry, TLS/PKI, backup and disaster recovery, and troubleshooting together with customer infrastructure, database, network, and security teams.

I also independently designed and built a fully local Voice AI system running on NVIDIA Jetson. It combines wake-word detection, speech recognition, local Gemma inference with llama.cpp, tool execution, text verbalization, Ukrainian stress assignment, and TTS. The platform includes a FastAPI inference router with REST, SSE, WebSocket, authentication, idempotency, and Prometheus metrics.

I am interested in remote Senior DevOps, Platform Engineering, AI Infrastructure, Edge AI, and systems-oriented MLOps roles. I am based in Kyiv and available for full-time remote B2B cooperation from Ukraine.
