AI & Automation Engineer · Founder, Nexus Code

I build AI-powered systemsthat run real businesses.

I'm Omar Daghestani. I design, ship, and operate production systems end to end — LLM workflows, AWS infrastructure, CI/CD, and data pipelines — for companies that need automation that holds up on a Monday morning.

Running Iron Buffalo's automation platform

About

Engineer, operator, founder

Portrait of Omar Daghestani

I started in support and teaching — helping enterprise SaaS customers at PowerSchool and mentoring 200+ developers at edX. That taught me what breaks in production and how to explain it to the people it breaks for.

In 2025 I founded Nexus Code, an independent AI and automation practice. My flagship engagement is Iron Buffalo Holdings, a multi-shop heavy-truck repair company, where I built and run a 30-system platform that handles their reporting, compliance, commissions, and customer portals. I also support enterprise healthcare infrastructure at Cognizant/TriZetto.

  • LLMs that earn their keep

    Claude wired into real workflows — auditing, classification, OCR, reporting — with evaluation behind every prompt.

  • Infrastructure I can sleep on

    Serverless AWS, least-privilege IAM, and drift detection so nothing changes in production without someone knowing.

  • End-to-end ownership

    From the first whiteboard sketch to the runbook — I build it, ship it, and stay on the hook for it.

Selected work

Things I've built

Production client work through Nexus Code, plus open-source projects you can run yourself.

Featured case studyIron Buffalo Holdings

A 30-system automation platform, built and run by one engineer

Through Nexus Code I architected, shipped, and operate the systems that run Iron Buffalo day to day — revenue reporting, compliance, commissions, and customer portals — with Claude woven into the workflows that used to eat hours of manual work.

Entities exposed via MCP

  • AI in production

    Claude API integrated into invoice auditing, service-request classification, handwritten-note OCR, and twice-daily AI-written operations briefings.

  • MCP server for the business

    A read-only MCP server on ECS Fargate that lets the team ask natural-language questions of the production SQL Server database.

  • DOT compliance platform

    Offline-capable digital inspections for DOT annual (49 CFR 396.17) and PM work, with countersignatures, dispatch queues, and randomized integrity checks that catch inspections signed off without being performed.

  • Fleet customer portal

    Externally authenticated portal (email OTP + JWT sessions) serving fleet-readiness and spend KPIs to the largest national fleet account.

  • Safe-deploy CI/CD

    GitHub Actions pipelines with deploy gates that harvest out-of-band production edits into pull requests, plus daily drift and job-heartbeat detectors.

  • Hardened API surface

    Closed a read-path SQL write bypass, enforced table whitelisting, flipped fail-open defaults to fail-closed, and wrote the credential-rotation runbook.
