What I can help you with

Based on real, hands-on experience supporting AWS customers. No fluff — only the things I know well.

🧾

Billing Support & Query Resolution

Confused by your AWS bill? I can walk through your charges, explain unexpected costs, and help resolve billing disputes or incorrect charges with clarity.

💸

Cost Optimisation & Savings Advice

I review your AWS cost data and usage patterns to find savings opportunities — including Reserved Instances, Savings Plans, and idle resource identification.

🧹

Account Cleanup & Resource Review

I help you identify and safely remove unnecessary resources — old snapshots, idle EC2s, unused Elastic IPs — that are quietly adding to your monthly bill.

🔐

MFA Troubleshooting & Account Access

Lost access due to MFA issues? I can guide you through the recovery process and help set up MFA correctly so it doesn't happen again.

📊

RI & Savings Plan Recommendations

Not sure whether to go with Reserved Instances or a Savings Plan? I'll analyse your workload and recommend the right commitment that saves the most money.

🔭

Cost Estimation for Upcoming Services

Planning to add a new AWS service? I'll give you a realistic cost estimate based on your expected usage before you commit — no surprise invoices.

Honest about scope: I focus on billing, cost, and account management — areas where I have real, hands-on experience. As I complete my MS in AI & ML, I'll be expanding into cloud + AI services. For now, I'd rather do fewer things well.
