About Mikhail
OpenClaw & Claude Code Engineer | MCP, AWS | SOC 2 HIPAA GDPR
100%
Job Success
Birmingham, United Kingdom - 2:56 am local time
Most OpenClaw and Claude Code stacks run fine in a demo. Very few survive a real audit, a 2 AM outage, or an enterprise security review. That gap is where I work.
WHO HIRES ME:
Legal, finance, healthcare, and compliance-bound SaaS teams with data residency and audit-trail obligations. Founders tightening security posture before a funding round, enterprise contract, or SOC 2 / HIPAA review. Engineering leaders inheriting an undocumented OpenClaw or Claude Code stack that breaks silently after model, MCP, or skill upgrades.
WHAT I DELIVER:
OpenClaw and Claude Code deployments hardened on AWS, GCP, Azure, DigitalOcean, and on-prem: SSL/TLS, encryption at rest, VPC segmentation, environment isolation, and automated backups configured on day one.
Docker and container baselines with non-root execution, read-only workspaces, least-privilege tool permissions, and full source-level skill and MCP audits.
Penetration testing across 10 to 20+ attack vectors (prompt injection, supply-chain compromise, persistent memory poisoning), delivered with a written Incident Response Playbook.
Zero-trust gateway hardening: localhost binding plus private access via Tailscale, WireGuard, OpenVPN, or Cloudflare Tunnel with mTLS.
Secrets management pipelines for Claude, OpenAI, and Gemini API keys, OAuth tokens, and messaging credentials, with rotation via HashiCorp Vault, AWS Secrets Manager, or GCP Secret Manager.
