Cloud architecture with operating discipline

Infrastructure that is reusable, secure, observable, and ready for real teams.

I am a senior cloud engineer who turns complex infrastructure needs into secure, automated, and dependable cloud systems. My work blends platform governance, infrastructure as code, automation, AI cloud integrations, serverless architecture, cost optimization, and hands-on operations across AWS, Azure, and GCP.

This portfolio highlights the kind of real-world cloud solutions I build: repeatable platforms, Bedrock-powered integrations, modernized APIs, resilient workloads, delivery pipelines, and operational controls that teams can confidently run and scale.

Selected project case studies

Cloud work with architecture, governance, and delivery baked in.

AI cloud integration

Bedrock Enterprise AI Assistant

A governed AWS Bedrock and Claude integration pattern for enterprise knowledge workflows, secure data access, vector search, prompt controls, and measurable model evaluation.

  • Integrated Bedrock, Claude, vector databases, S3, Secrets Manager, and API-backed workflows.
  • Applied prompt engineering, guardrails, evaluation loops, and least-privilege access controls.
  • Designed for production stakeholders who need AI capability without losing governance.

Enterprise platform

Enterprise Cloud Landing Zone

A governed AWS, Azure, and GCP foundation with identity controls, tagging standards, cost visibility, account guardrails, and repeatable infrastructure patterns.

  • Built around Terraform, CloudFormation, IAM, org policies, and access governance.
  • Reduced manual provisioning with AWS CLI, Azure CLI, PowerShell, and Python automation.
  • Designed for enterprise stakeholders, vendors, architects, DBAs, and delivery teams.

Serverless integration

Enterprise API and Data Modernization

A cloud-native API layer using AWS API Gateway and Lambda to integrate business workflows with Oracle, SQL Server, Redshift, and downstream enterprise systems.

  • Modernized core services without forcing large database rewrites.
  • Added secure IAM boundaries, Secrets Manager patterns, and environment separation.
  • Partnered with architects, DBAs, and developers from design through delivery.
API Gateway Lambda Oracle Redshift

Reusable infrastructure

Terraform Module Factory

A version-controlled module library for provisioning Lambda, API Gateway, IAM, S3, EventBridge, VPC peering, and security groups with consistent patterns.

  • Standardized infrastructure delivery across projects and environments.
  • Made reviews easier by replacing one-off templates with reusable building blocks.
  • Improved onboarding and delegation for junior engineers and implementation teams.

Migration and modernization

Media Transfer Cloud Redesign

A modernization effort for file and media transfer workloads, moving brittle manual operations toward cloud-native storage, automation, and monitored execution.

  • Assessed current workflows, dependencies, operational risks, and target cloud patterns.
  • Reframed manual transfers into repeatable, observable pipelines.
  • Prepared the system for future integrations with vendor and core business systems.
AWS S3 Automation Monitoring

Security automation

KMS and IAM Access Control Framework

A secure access model for cloud services using IAM roles, resource policies, KMS keys, security groups, IP allowlisting, VPN patterns, and network controls.

  • Managed cryptographic keys for controlled access to AWS services and workloads.
  • Created least-privilege IAM patterns for users, groups, roles, and policies.
  • Supported compliance audits, secure vendor connectivity, and cloud hardening practices.

Cloud financial operations

Cost Intelligence Workbench

A cost analysis workflow using AWS Cost Explorer, CUR, Azure Cost Management, Resource Graph, and custom scripts to expose savings opportunities.

  • Mapped spend trends across AWS and Azure resources for operational decision-making.
  • Identified underused services, tagging gaps, and governance improvements.
  • Turned cost reviews into repeatable reporting instead of occasional manual checks.
Cost Explorer CUR Azure Cost Resource Graph

Resilient web platform

High-Availability LAMP and WordPress Stack

A fault-tolerant AWS web hosting pattern using EC2, RDS, Auto Scaling, Elastic Load Balancing, Apache, Nginx, and hardened Linux hosts.

  • Provisioned VPC networking, local and external databases, EC2 hosts, and RDS instances.
  • Configured Auto Scaling and load balancing for resilience and availability.
  • Supported deployments through Git and team-based release processes.

Observability

Compliance and Monitoring Control Room

A monitoring approach for cloud resources using CloudWatch, CloudTrail, AWS Config, Splunk, Grafana, ELK, and event notifications.

  • Tracked operational health, configuration drift, audit trails, and security events.
  • Supported troubleshooting for AWS resources and application workloads.
  • Improved change visibility across infrastructure and delivery pipelines.
CloudWatch Splunk Grafana ELK

Delivery automation

CI/CD Delivery Backbone

Automated release workflows across Git, Jenkins, Azure DevOps, GitHub Actions, Terraform, and cloud deployment gates.

  • Connected source control, build steps, infrastructure changes, and deployment gates.
  • Supported Agile delivery with traceable work through Jira and collaborative reviews.
  • Reduced manual handoffs between development and cloud operations.
