What I'm looking for

I seek backend/platform roles where I can architect scalable, reliable distributed systems, lead cloud-native initiatives, and integrate ML workflows in collaborative, growth-oriented teams.

I am a Senior Backend Software Engineer with 10+ years designing, building, and operating scalable, high-performance backend systems across enterprise, research, gaming, and media environments. I deliver secure APIs, high-throughput data pipelines, and microservices-based platforms using Python, Java, C#, Go, and TypeScript, with production experience supporting millions to billions of records and integrations with Google, Sony Interactive Entertainment, and Electronic Arts.

My work emphasizes reliability and maintainability: I architect distributed services, model strongly consistent schemas, and implement resilient patterns (asynchronous processing, idempotent writes, retries, backpressure). I have led migrations, reduced latencies and processing times, and developed AI-ready workflows and ML-augmented automation that improve operational efficiency and developer velocity.
