Who am I?

5+ years building and automating infrastructure across cloud and on-premise environments. I specialize in DevOps pipelines, Python automation, and cloud architecture on AWS and Oracle Cloud. On the on-prem side, I've racked and provisioned physical servers, managed Citrix XenServer and XCP-ng virtualization environments, and administered Fortigate firewalls — including rule policies, site-to-site VPNs, and traffic security. From Kubernetes clusters to bare-metal racks, I build things that actually work in production. Currently open to freelance projects and part-time contracts.

Project & Repositories

Here are some of my projects that solve real-world infrastructure and automation problems.

XCP-ng Server Snap

Manual VM backups are error-prone and easy to forget. This Python + Bash script snapshots every running VM on a XCP-ng hypervisor and sends email confirmation once backups complete — zero manual intervention.

AWS Secrets Manager Fetcher

Manually copying secrets from AWS Console is slow and insecure. This Python CLI tool pulls key-value pairs from AWS Secrets Manager and stores them as structured JSON — ready for app config or CI/CD injection.

Apache SSL Date Checker

Expired SSL certificates cause downtime and browser warnings. This Python script checks SSL expiry dates across multiple domains and logs results to MongoDB — with alerting for certificates expiring within 30 days.

Invoice Generator (Private)

Small businesses need invoicing without the cost of Tally or Zoho. A full-stack Node.js app that generates professional invoices, exports as PDF, and emails them directly to buyers.

Location Alarm (Private)

Commuters on trains and buses often miss their stop. A Kotlin-based Android app using Google Maps GPS that triggers an alarm when approaching your destination — set it and sleep.

Heavy Vehicle Tracking & Booking (Private)

Fleet managers lose money without real-time vehicle visibility. A full-stack system with live GPS tracking, fuel consumption logs, km-driven records, and meter-based trip booking — all stored in MySQL with Google Maps integration.

On-Premise Infra & Network Security

Built and managed a multi-server on-premise environment — racked physical servers, deployed Citrix XenServer and XCP-ng VMs. And administered Fortigate firewalls with VPN, traffic monitoring, and security policies. Result: stable, secure, fully monitored infrastructure.
