AI/ML REST Services Deployment

Build, expose, and scale model inference APIs (REST/GraphQL) and microservices; validate endpoints and automate documentation (VDD, release notes) for production deployment.

Cloud Services & DevSecOps

Design and manage AWS workloads (EC2, EKS, Lambda, S3, CloudWatch, SNS/SQS) and containerized deployments (Docker/Kubernetes) within CI/CD toolchains (Jenkins/GitHub).

Apply infrastructure‑as‑code (Terraform/CloudFormation/Ansible) to deliver repeatable, compliant environments with shift‑left security and automated evidence for ATO.

Artificial Intelligence & Machine Learning

Lead model selection, training, tuning, and evaluation (supervised, unsupervised, reinforcement learning); apply NLP, computer vision, and agentic/GenAI approaches to mission use cases.
