Software Engineer @ Samsung R&D \| Backend & Distributed Systems \| Java \| Spring Boot \| AWS \| Kubernetes ## About I build backend platforms that scale, ship reliably, and make engineering teams faster\. I’m a Senior Software Engineer at Samsung R&D Institute, Bengaluru, with hands\-on experience across backend engineering, distributed systems, DevOps, cloud infrastructure, CI/CD automation, observability, and data platforms\. My work sits at the intersection of product engineering and platform reliability\. I’ve built and optimized systems that process 80M\+ audio samples, migrated 12 critical Spring Boot microservices from EC2 to AWS EKS, enabled zero\-downtime deployments, reduced rollback time by 70%, improved API latency by 30%, and helped platforms reliably support 100K\+ concurrent users\. Technically, I specialize in: Backend Engineering: Java, Spring Boot, REST APIs, gRPC, microservices, Kafka, Redis Cloud & DevOps: AWS, EKS, Kubernetes, Docker, Helm, ArgoCD, GitHub Actions, GitOps Data & Storage: PostgreSQL, MySQL, Elasticsearch, Redis, schema optimization, GIN indexing Observability: Prometheus, Grafana, Loki, Tempo, Mimir, alerting, distributed tracing Engineering Ownership: architecture, deployment automation, performance optimization, production reliability What differentiates me is that I don’t just write services, I take ownership of the full engineering lifecycle: architecture, implementation, testing, deployment, monitoring, and reliability\. I enjoy solving ambiguous backend problems, simplifying complex systems, and building tooling that improves developer velocity\. I’m currently targeting SDE\-2/Senior Software Engineer/Backend Engineer/Platform Engineer roles where I can build scalable backend systems, own high\-impact end\-to\-end services, and contribute to engineering cultures that value ownership, craftsmanship, and reliability\. ## Location Bengaluru ## AI stack claude code codex gemini Cline ## Work experience Senior Software Engineer at Samsung R&D Institute India \- Bangalore, Mar 2023 \- Present · 3 yrs 8 mos, Project: Bixby ASR — Automatic Speech Recognition – Redesigned the ASR inference serving architecture by integrating NVIDIA Triton with the Java\-based ASR Engine and evaluating in\-process and vLLM sidecar deployments, achieving up to 3x faster batch inference, 5% lower streaming latency, and 2x concurrent request capacity\. – Integrated an internally trained SLLM into the production serving architecture, improving time\-to\-first\-token \(TTFT\) by 8% while maintaining the existing Java\-based inference workflow\. – Architected a high\-scale metadata platform for 80M\+ audio samples, designing optimized PostgreSQL schemas and GIN indexes with Elasticsearch integration to enable efficient dataset discovery, filtering, and retrieval\. – Led ASR model deployment and lifecycle management on AWS EKS, driving improvements across model release pipelines, deployment automation, and operational reliability for production ML workloads\. – Automated model release workflows using Python, Shell, CI/CD, and GitOps, reducing manual deployment and release effort by 50% through reproducible, version\-controlled deployments\.
