I have worked on enterprise Sanity projects at Bejamas, leading and setting up many of them from the start. I design content models and Studio workflows, then connect them to Next.js or Astro frontends. I have worked with editors across regions and large content sets. #### What have you built with Storyblok? I have shipped Storyblok projects with component schemas, multilingual content and frontend preview. #### Have you led migrations from an existing CMS? Yes. I have worked on migrations involving headless WordPress, Contentful, Sanity and Storyblok. I map the source content and relationships to the new model, test the migration on a sample, then estimate the full volume and cutover. #### What does agent-assisted delivery look like in your team? I use Claude Code and Codex daily for bounded implementation work. I give them project context and acceptance criteria, review their changes in small pull requests, and keep architecture and release decisions with the responsible engineer. #### How do you check work produced by developers or coding agents? I review the behavior against the brief, read the code for architectural and security mistakes, and run the relevant tests. For a frontend change I also check the rendered page at real screen sizes. I also check that a visitor can understand and use the change. #### What leadership experience do you have? I lead frontend delivery on Next.js and Astro projects, make technical decisions, direct mid-level developers and mentor new engineers. I have led multilingual and regional projects. I also served as an interim engineering manager at Bejamas, including recruitment interviews. #### What external integrations and performance work have you done? For the NNOXX shop I connected Swell, Azure Functions and the shipping services through webhooks. I have worked on large Next.js sites where rendering and build time mattered, and I investigate Core Web Vitals by measuring real routes and tracing slow behavior to its cause. ## Get in touch Tell me about your website or the decision you need help with.
