135,000+ OpenClaw instances are currently exposed to the public internet. 78% are running unpatched versions with known remote code execution vulnerabilities. State-sponsored hacking groups are actively targeting them. I specialize in secure OpenClaw AI agent deployment. Every setup includes a 13-point security hardening checklist, API spending cap configuration, and end-to-end testing — so your AI assistant works without exposing your infrastructure or running up a surprise API bill. What I deliver: Secure installation on your server or cloud VM (GCP, DigitalOcean, AWS) Full security hardening: localhost binding, firewall rules, Fail2Ban, credential rotation, Docker sandboxing API cost protection: spending caps, model optimization, usage monitoring Messaging channel setup (Telegram, Discord, WhatsApp, Slack, Signal) Skill auditing and installation from ClawHub Client walkthrough and handoff documentation Optional monthly retainer for ongoing security patches, cost monitoring, and maintenance Whether you need a personal AI assistant locked down tight or a business-grade deployment with custom workflows, I'll make sure it's secure, cost-efficient, and production-ready.

I am an active and self managed software engineer, eager to get his hands dirty solving challenging problems for organizations of all sizes. My past experience has given me vast knowledge into multiple different infrastructures (Nutanix AHV, vmware ESXi, OpenStack KVM, etc). With strong automation skills, I have architected an end to end deployment utilizing vRealize Automation & Orchestrator with deep integration with SaltStack and multiple vCenters. I managed to reduce the number of templates to manage along with a much more reliable provisioning and decom process. I have also repeated the same with Scalr, however instead of vCenter, I used Azure & OpenStack. In my part time, I have a hotel booking site I managed that I have hosted on Azure along with multiple other sites that I've hosted on GCP and AWS. I like to learn about what each product has to offer and utilize the strong points of each. I developed full stack applications along with simple micro-services with .NET C# / Django Python / Java. These applications varied from being simple websites with backend management to building sophisticated IP Address management tools and batch job like applications.
