AI Automation & Business Process Engineer | Claude Code | Fast+Secure
100% Job Success
4.8  (30 reviews)
Birmingham, United Kingdom - 8:16 pm local time
Most AI automations look great in a demo and quietly break in production. I build the ones that actually run your business, deployed in about a week and hardened from day one.

I'm an AI automation engineer who turns slow, manual business processes into reliable systems that pay for themselves fast. Using Claude Code, MCP, and modern AI tooling, I ship working automations in days, not quarters, then lock them down so they survive real traffic, security reviews, and 2 AM edge cases.

What I automate (and the payback that follows):

Lead-to-cash workflows: intake, qualification, CRM sync, and follow-up that recover hours every week and stop deals slipping through the cracks.

Document and data pipelines: contracts, invoices, reports, and records parsed, routed, and filed automatically with full audit trails.

Internal ops and back-office: onboarding, ticket triage, reporting, and approvals wired together across the tools you already use.

Custom AI agents: Claude-powered assistants and MCP integrations connected to your real systems, not a sandbox.

How I work:

1. Scope call: we pin down the one process costing you the most time or money.
2. Build sprint (days, not months): I ship a working automation fast, with you reviewing progress along the way.
3. Harden and hand off: secrets management, least-privilege access, encryption, and a written runbook so it keeps running after I'm gone.
4. Live in about a week: most projects deliver measurable payback within the first week or two of going live.

Why clients hire me over a cheaper option: speed and security usually come as a trade-off. I deliver both. Every build ships with non-root containers, isolated environments, secrets rotation (Vault or AWS Secrets Manager), and SOC 2, HIPAA, and GDPR-aligned practices baked in, so what works in week one still passes an audit in month six.

Stacks: Claude Code, MCP, OpenAI, Gemini. AWS, GCP, Azure, DigitalOcean, on-prem. Docker, Tailscale, Cloudflare Tunnel, WireGuard.

Best fit for: founders and ops or engineering leaders in legal, finance, healthcare, and compliance-bound SaaS who need automation that's fast to ship and safe to trust.

A quick first step: message me the one process eating the most time in your week. I'll send back a short, no-obligation plan for automating it, usually within a couple of hours during business hours.
