Services and selected work

Application Development

Web and SaaS apps built on a variety of different architectures and tech stacks.

Headless Content Management (CMS)

Move at the speed of ROI with content that is created, iterated, experimented on and reused across many channels and platforms. I build fast, shareable, SEO optimized sites on CMS platforms like Contentful, Builder.io, Sanity.io, Storyblok and WordPress, delivered on content optimized hosting platforms like Vercel, Netlify and Cloudflare.

Data and Growth Platform Integration

To maximize growth, ROI and optimize user experience, I help you evaluate and integrate top experimentation, marketing and sales automation, customer service, analytics and customer data platform and recommendation tools like Klaviyo, Braze, Iterable, Segment, Intercom, Drift, Hubspot, Google Analytics, Heap, Amplitude, Salesforce and more.

AI Integration

For the right use cases, AI can provide great value. I help you evaluate and integrate tools in the marketplace or use leading APIs, platforms and SDKs to build chat, semantic search, recommendations, embeddings or retrieval augmented generation from multiple data sources.

Software Quality

Unit, e2e and UI testing, using the latest tools including AI where applicable and integrated into CI/CD or stand alone.

Flexible workflow

I can integrate seamlessly into your existing development team, workflow and tools, architect a workflow for greenfield projects or work completely as an outside agency. The choice is yours.

Security

All work is done to OWASP top 10 security standards.
