AI automation, engineered for production.

I design and build AI agents, automated pipelines, and custom web platforms that do real work — shipped with the tests, guardrails, and CI to prove it.

What I build

From single automations to full platforms — scoped, built, and shipped with the guardrails to keep them running.

  • AI Agents & Orchestration

    Autonomous agents that plan, code, test, and deliver, with human-in-the-loop approval gates and sandboxed execution.

  • AI-Powered Products

    AI features woven into real products: content generation, monitoring, recommendations.

  • Workflow & Data Automation

    Scheduled ingestion, background job pipelines, alerts, integrations.

  • Custom Web Platforms

    Marketplaces and SaaS platforms, end to end.

  • Browser Extensions

    Chrome MV3 extensions with local-first architecture and optional cloud sync.

  • E-commerce Engineering

    Performance-first WooCommerce builds.

AI Automation · FlagshipFlagship

Girder

Process

How I Work

Small scope, fast feedback, production from day one.

  1. 01

    AI-first, human-approved

    My own repos run on AGENTS.md, OpenSpec, and AI agents daily; I build the guardrails that make agents safe in yours.

  2. 02

    Production-grade by default

    Typed codebases, migration discipline, test suites, CI pipelines.

  3. 03

    Privacy-minded

    Local-first architectures, minimal personal data, GDPR-aware features.

  4. 04

    Full lifecycle

    Architecture → build → deploy → monitor.

Let’s build something that does real work.

Have a process to automate, a pipeline to harden, or a platform to build? Tell me what it needs to do — I’ll tell you how I’d ship it.
