Claude AI Trainer and Technical Coach
Upwork • Freelance
Apr 2026 - Present • 5 mos
Trained a development team on using Claude effectively across the software development lifecycle, covering Claude Code, the Claude API, and Claude through IDE/CLI tools. Ran hands-on sessions on AI assisted coding, code review, and debugging, and set the team up with reusable prompt patterns and custom instructions (CLAUDE.md and prompt.md conventions) instead of ad hoc prompting. Introduced guardrails and QA practices for reviewing AI generated code before merge, and left the team with internal documentation they could keep using after the engagement ended.

Development and deployment of an MVP hair products marketplace.
Full Stack Developer, Landing Pages and SaaS Web Apps
Upwork • Freelance
Dec 2025 - Present • 9 mos
Built landing pages and lightweight SaaS web applications using Claude Code, from initial planning through deployment. Work spanned frontend build out, backend logic, and database setup, using Claude to move faster while still applying real engineering practice: structured requirements, staged builds, and a review pass on AI generated code before anything shipped. Delivered production ready sites and apps for founders needing a working product quickly rather than a static prototype.

Good work, But he doesn't live in England, and his written English is not 100%. But overall happy with his work. Would I use him again? Yes probably. Just be honest with your location. So we can work out the time difference.

Great experience working with Joel. Very quick responses, extremely professional and dedicated. He worked many hours to make sure everything was set up correctly, including the full Paddle integration which is not easy at all. The communication was smooth and the delivery was exactly as requested. Highly recommend!

⭐️⭐️⭐️⭐️⭐️ 5 Stars Joel is one of the most talented and dedicated developers I’ve ever worked with on Fiverr. He understands complex ideas quickly, communicates clearly, and delivers with a level of professionalism that is very rare. He didn’t just “do the job” he thought ahead, suggested improvements,...
