Questions about my work
For hiring managers
How deep is your Sanity experience?
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.
