About the Role

We are undertaking a platform migration from our existing WordPress site to a modern React frontend. We are seeking a highly capable Backend Engineer on a 1-month contract to lead the backend aspects of this transition. The ideal candidate has strong experience with serverless backends and API-first architectures, particularly using Cloudflare Workers and the Cloudflare ecosystem. You will collaborate closely with our in-house Frontend Engineer (specialized in React) to deliver a seamless, performant, and secure end product.  

Key Responsibilities

Audit current WordPress backend (data structures, plugins, custom code). Design and implement a backend solution leveraging Cloudflare Workers, Cloudflare KV / Durable Objects, and related services (or propose suitable alternatives such as Node.js/Express or headless CMS if appropriate). Develop secure APIs for authentication, content, and form handling. Migrate existing WordPress data (pages, posts, forms, and media) into the new system. Integrate with our CRM (_Zoho_) and other existing systems. Ensure compliance with NZ data protection standards. Deploy backend on Cloudflare (and/or coordinate with existing hosting infrastructure as needed). Provide documentation and handover to the internal team.

Qualifications & Skills

Proven experience in backend engineering with serverless platforms (Cloudflare Workers, AWS Lambda, or similar). Strong knowledge of RESTful APIs, authentication, and security best practices. Familiarity with Cloudflare KV, Durable Objects, R2, or equivalent distributed data solutions. Experience with WordPress architecture and React-based frontend integration. Experience in migration projects (legacy CMS → modern stack) highly valued. Strong collaboration and communication skills, with the ability to work effectively alongside frontend specialists.

Deliverables

Backend environment and Cloudflare Worker (or alternative) architecture established. Secure APIs deployed and tested with React frontend. Migration of content/data from WordPress. Integration with Zoho CRM and forms. Production deployment. Documentation + handover.

Duration: 1 month.

Engagement: Remote, with short daily and hourly weekly check-ins.

Compensation: 75,000 INR

Experience with Cloudflare Workers, the Cloudflare CDN, prior Wordpress migration experience, and any experience of working alongside frontend engineers prioritized. A huge bonus would be experience with Zoho CRM/Zoho Forms.
