Senior Backend Engineer | Java & Go | Distributed Systems · AI InfrastructureI sometimes write technical articles @ https://chkrishnatej.dev I build backend systems that enterprises depend on. The kind where reliability is the baseline, not a feature.Currently at IBM, working on the platform layer for IBM Spectrum LSF. REST APIs, CLI tooling, and hybrid cloud integration for distributed compute infrastructure, including AI and HPC workloads. Before this, I was at Oracle building backend services for a large-scale document management platform. Event-driven pipelines, microservices under real production load.Core: Java, Go, event-driven architectures, distributed systems and data pipelines. Increasingly focused on the infrastructure layer that makes AI workloads reliable at scale. Compute orchestration, resource scheduling, model serving infrastructure.

Experience

1. Senior Software Engineer

   IBM

   Jul 2024 — Present · Hyderabad, IN

   Architected and implemented RESTful APIs for IBM Spectrum LSF Web Services using a hybrid stack of Golang and Java (Spring Boot) to streamline job submission, monitoring, and integration with external automation systems.• Developed both backend services in Go and supporting components in Java to enable high-throughput, low-latency communication between on-premises LSF clusters and cloud platforms, ensuring seamless overflow job processing and dynamic workload balancing.• Designed and delivered a Golang-based CLI tool, empowering developers and SREs with fast, scriptable interfaces to interact with the LSF ecosystem, accelerating DevOps workflows.• Ensured secure, scalable, and observable service architecture using modern backend best practices—service orchestration, metrics instrumentation, and robust error handling.• Played a key role in modernizing legacy components, gradually transitioning workloads from Java to Golang where performance and maintainability could be significantly improved.• Implemented OAuth 2.0 authentication and authorization by integrating enterprise Identity Providers (IDPs) such as Okta/Keycloak, enabling secure, standards-compliant access control for internal APIs and tools.• Developed Role-Based Access Control (RBAC) mechanisms across both Java (Spring Security) and Golang services, ensuring consistent user permissions, session management, and auditability across distributed microservices.
