Senior Full-Stack Developer — AI & Business Applications
Remote contract | Ongoing work for the right person
We’re looking for an experienced full-stack developer to help us build and improve a range of applications and systems across our businesses.
You’ll work directly with the company CEO to understand business needs, discuss ideas and turn them into clear, working software. Strong communication is important: you should be comfortable explaining technical matters in plain English, asking questions when requirements are unclear and giving regular progress updates.
One of the systems you’ll work on is our AI customer-service platform. It uses React and supports email, WhatsApp, website live chat and telephone, with customer history, tickets and AI-assisted replies. There will also be opportunities to develop other customer-facing applications, admin tools and business workflows.
We use modern AI development tools, including Claude and AI coding agents. We’re looking for someone who can use these tools effectively while taking responsibility for the quality, security and reliability of the finished software.
What you’ll work on
- Build and improve applications and systems across several businesses.
- Review existing software before recommending major changes or a rebuild.
- Develop customer-facing applications, admin tools and business workflows.
- Integrate AI models into applications, including chat and conversational features.
- Connect systems and services through APIs.
- Improve reliability, data protection, monitoring, backups and deployment.
- Keep code organised and documented so another developer can maintain it.
- Work directly with the CEO to clarify requirements, agree priorities and report progress.
- Explain technical choices and problems clearly to a non-technical business owner.
What we’re looking for
- Strong experience building and maintaining real software.
- Good knowledge of React or Next.js, TypeScript or JavaScript, backend APIs and databases.
- Hands-on experience integrating the OpenAI API into an application, including conversational chat features.
- Understanding of conversation history, tool or function calling, error handling and API usage costs.
- Sound judgement about customer data, access controls, reliability and human approval.
- Comfortable using Claude Code, Cursor or similar AI development tools.
- Clear, professional written and spoken English.
- Reliable communication: able to explain progress, raise problems early and ask for clarification when needed.
- Able to show examples of systems you’ve built and explain what you personally delivered.
Experience with Anthropic’s Claude API, PostgreSQL, WhatsApp, telephony, email integrations, cloud hosting and multi-business platforms would be useful.
How to apply
Please send:
- Links or screenshots of systems you’ve built that are live or in active use.
- A short explanation of your role in building them.
- The technologies you used and how you handle testing, deployment and backups.
- Examples of your OpenAI API work, especially chat or conversational features.
- Your availability, location and monthly or project rate.
- A short example of how you would keep a non-technical CEO updated during a development project.
We’ll begin with a paid one-month trial project with agreed deliverables. The company will own the project accounts and code. Work must be documented so another developer can maintain it or take over. Applicants from Pakistan and India are welcome.
