What I'm looking for

Looking for a remote Senior DevOps or Platform Engineering role where I can design and scale cloud-native infrastructure, improve deployment pipelines, and drive automation, reliability, and observability across engineering teams. Prefer product-oriented teams with mature tech culture and clear ownership.

DevOps Engineer with over 10 years of experience, a strong passion for technology, and a commitment to continuous professional growth. My expertise spans areas such as bare-metal and cloud infrastructure, orchestration, containerization, CI/CD pipelines, Infrastructure as Code (IaC), observability, and database management.

I excel in both collaborative and independent tasks, with extensive experience in industries such as e-commerce, fintech, video broadcasting, system integration, and game development.

Key Highlights:

- Designed and implemented a multi-region fault-tolerant infrastructure supporting around 8,000 CCU, ensuring high availability and low latency for real-time workloads.

- Migrated projects to Kubernetes, reducing deployment time from several days to 5–10 minutes

- Enhanced observability and scalability using stacks such as VictoriaMetrics, Prometheus, EFK, DataDog, Sumo Logic, and New Relic, ensuring proactive incident management and seamless scaling during peak loads.

- Migrated databases to managed solutions like MongoDB Atlas and ElastiCache, improving reliability and reducing operational overhead.

- Delivered cost-optimized cloud solutions, enhancing performance while maintaining budget efficiency.

I firmly believe that well-implemented DevOps practices not only accelerate product delivery but also foster stronger team collaboration, improved workflows, and long-term business success.
