Struggling with unreliable infrastructure, VMware licensing costs, or a stalled cloud migration? I'm a DevOps & Cloud Engineer who builds and stabilizes production environments across AWS, Azure, Proxmox, and Ceph — with a focus on uptime and automation.
Most DevOps engineers specialize in either cloud or on-prem infrastructure. I do both: I've run production Proxmox VE clusters with Ceph storage alongside AWS, Azure, and GCP deployments, and I handle VMware-to-Proxmox migrations end-to-end — a combination few freelancers on Upwork cover with hands-on production experience.
Here's how I typically help clients:
✔ Design and deploy cloud infrastructure on AWS, Azure, or GCP
✔ Build and troubleshoot Proxmox clusters, including VMware-to-Proxmox migrations
✔ Optimize and recover Ceph storage clusters
✔ Set up Docker and Kubernetes environments with CI/CD pipelines
✔ Implement monitoring with Zabbix and Grafana
✔ Plan and test backup and disaster recovery strategies
✔ Secure infrastructure with VPNs, firewalls, and Zero Trust practices
Top Rated Plus on Upwork with a 4.98 rating across 51 completed jobs and over 2,870 hours worked. AWS Cloud Practitioner Essentials certified. Clients include startups, MSPs, SaaS companies, and enterprise teams relying on me for production-grade infrastructure.
Send me a message with what you're working on and I'll respond with next steps within a few hours.

As an AWS-certified DevOps and cloud security engineer, I help startups, fintech companies, and AI/ML platforms build secure, compliant, production-grade AWS infrastructure — including the AI infrastructure layer most DevOps engineers haven't touched yet: LLM inference endpoints, RAG pipelines, and GPU-backed compute.
With certifications in AWS DevOps Engineer – Professional, AWS Security – Specialty, AWS CloudOps Engineer – Associate, and AWS Solutions Architect – Professional (in progress), your infrastructure is in capable, currently-certified hands.
WHAT I DO BEST
AI/ML Infrastructure on AWS
I deploy fine-tuned LLM inference endpoints across GPU instance families, build RAG knowledge bases using Amazon Bedrock and pgvector, and stand up Feature Stores for ML pipelines — all on Terraform, all production-grade. If your platform runs AI workloads, I build the infrastructure underneath the model.
Enterprise Cloud Foundation & Governance
I establish AWS cloud foundations using Control Tower and Landing Zone with automated multi-account environments and security guardrails — Security Hub, GuardDuty, AWS Config, CloudTrail, and SCPs. This significantly eases SOC 2, ISO 27001, and HIPAA audit preparation through automated compliance evidence.
Security-First Infrastructure
VPC isolation, least-privilege IAM, secrets management, and encryption everywhere. A recent project passed a SOC 2 audit with zero infrastructure findings, built in from day one.
Cloud Migrations & Containerization
I migrate applications from on-premises and legacy clouds (GCP, Azure) to AWS with zero downtime — deploying to ECS/Fargate, EKS, or traditional EC2, with a focus on cost efficiency and security.
Infrastructure as Code
Everything is Terraform-based, version-controlled, and reproducible — multi-account Control Tower setups, VPC architectures, IAM policies, all defined as code with peer review.
CI/CD & Production Reliability
Deployment pipelines (GitHub Actions, GitLab CI, AWS CodePipeline) that cut deployment time from hours to minutes, with automated testing and rollback. Designed for 99.99% uptime through Multi-AZ deployments and auto-scaling.
RECENT RESULTS
- Architected GCP-to-AWS migration for an AI/ML fintech platform — 5 fine-tuned LLM inference endpoints across GPU instance families, RAG knowledge base on pgvector, full Terraform IaC
- Deployed a containerized Spring Boot app on ECS Fargate with Control Tower multi-account setup, Security Hub, GuardDuty, Config, and CloudTrail across dev/staging/prod
- Migrated a payment platform to AWS — 99.99% uptime, handled 10x traffic spikes, 40% cost reduction
- Delivered enterprise Landing Zone migration framework for 85 applications, 450 VMs, 55 databases
- Automated deployments from 2 hours to 15 minutes with improved security posture
TECH STACK
AWS AI/ML: Amazon Bedrock, Amazon SageMaker, RAG pipelines, pgvector, Feature Store, GPU instances
AWS Governance & Security: Control Tower, Organizations, Security Hub, GuardDuty, Config, CloudTrail, IAM, Secrets Manager, KMS, WAF
AWS Infrastructure: ECS/Fargate, EC2, Lambda, RDS, DynamoDB, S3, VPC, CloudFront, ALB/NLB, Auto Scaling
Containers & Orchestration: Docker, ECS/Fargate, Kubernetes/EKS, ECR
Infrastructure as Code: Terraform (5+ years), CloudFormation, AWS CDK
CI/CD: GitHub Actions, GitLab CI, Jenkins, AWS CodePipeline/CodeBuild/CodeDeploy
Databases: RDS (PostgreSQL, MySQL, SQL Server), DynamoDB, MongoDB/DocumentDB
Monitoring: CloudWatch, CloudTrail, VPC Flow Logs, Security Hub, Config
Scripting: Python, Bash, Shell
WHO I WORK WITH
- AI/ML platforms needing production-grade inference and RAG infrastructure
- Startups preparing for SOC 2 certification
- Fintech companies needing secure infrastructure for financial data
- Healthcare/SaaS companies requiring HIPAA-ready environments
- Companies migrating from on-premises, GCP, or Azure to AWS
- Enterprises needing multi-account AWS governance
WHAT MAKES ME DIFFERENT
Most DevOps engineers deploy applications. I build enterprise security foundations — and the AI infrastructure layer most of them haven't touched yet.
You get:
✓ AI/ML infrastructure built by someone who understands both the model and the cloud underneath it
✓ Security and compliance built in from day one
✓ Automated audit evidence collection
✓ Multi-account governance preventing drift
✓ Clear documentation and knowledge transfer
Looking for secure, audit-ready AWS infrastructure — or AI/ML platform infrastructure that actually scales? Let's talk.

Given that the organization is publicly traded (HOSE: BVH), it mandates the highest security level measures. One of my core duties is to manage the whole infrastructure and servers, ensuring full operational capacity, functionality, and security, as below:
■ Optimizing test automation, trunk-based development, and working in small batches
■ Consciously tracking and reporting on change failure rates
■ Implementing an automated deployment pipeline that incorporates automated testing and feedback mechanisms
■ Continuously monitoring system health and alerting operations staff in the event of a failure
■ Equipping operations staff with the necessary processes, tools, and permissions to resolve incidents
