I build AI-powered web applications and the production systems that keep them reliable, from architecture to launch. Teams work with me for engineering that ships fast without failing quietly: clean React and Next.js front ends, headless CMS pipelines, and safeguards that surface problems loudly instead of hiding them.
From Contentful publishing workflows to AI features and commerce integrations, I connect architecture decisions to clear interfaces, validation and release checks. Explore the services, technical writing and approved work behind each capability.
Structured requests and outputs, bounded usage and explicit human review help turn an AI feature into a workflow people can evaluate. Retrieval and model evaluation belong in the design when the use case requires them.
Contentful GraphQL, validated content contracts, protected preview and webhook revalidation connect editorial work to reliable page delivery.
App Router rendering, structured metadata and checks against the exact deployment keep page behavior and release evidence connected.
Shopify Plus, storefronts and catalog integrations need clear boundaries between content, commerce APIs and checkout. I scope migrations and verification around the customer journey.
Failure handling, Sentry, CI checks and CSP reporting make release problems visible and support verification before promotion.
Performance and reliability services
Semantic components, visible labels, keyboard checks and automated accessibility tests make core flows easier to use and review.
