Design, execute, and operationalize fine-tuning workflows for large language models (supervised, DPO, RLHF). Lead dataset curation, build scalable distributed training pipelines, optimize training stability and throughput, implement parameter-efficient tuning (LoRA/QLoRA), design evaluations and safety testing, operate GPU cluster jobs, manage model artifacts, and mentor engineers to productionize responsible LLM deployments.

Design and build high-performance backend services, Kubernetes-native applications, and infrastructure tooling in Go. Implement gRPC/REST APIs, messaging and datastore integrations, observability, testing, and performance optimization. Mentor engineers, lead reviews, contribute to shared libraries and documentation, and ensure production reliability and operational readiness.

Design and deliver multi-cloud strategy and reference architectures across AWS, Azure, GCP, and OCI. Define federated identity, cross-cloud networking, IaC/policy-as-code patterns, container/Kubernetes and serverless strategies, observability, security, FinOps, disaster recovery, and provide architecture artifacts and guidance to engineering teams.

Design, build, and maintain scalable Java/Spring Boot microservices and responsive React front-ends. Implement RESTful APIs, event integrations, automated tests, CI/CD pipelines, cloud deployments, performance tuning, and architecture improvements while collaborating in Agile teams.

Define and lead the enterprise data platform architecture across ingestion, storage, processing, governance, and consumption. Drive standards for data modeling, pipelines (batch & streaming), governance, security, cost optimization, disaster recovery, and platform enablement while mentoring engineers and partnering with ML/BI/product teams.
