You will get a Custom AI Web App using Next.js, React, and OpenAI
Project details
Are you looking to build a high-performance AI web app or launch your next SaaS MVP?
I am a Product Engineer specializing in scalable, data-intensive web apps using Next.js, TypeScript, and AI pipelines. I don't just write code—I architect systems that load instantly and look beautiful. I've built production systems ranging from national platforms handling 1,000,000+ users to complex AI video apps with strict sub-second performance metrics.
What I build:
• AI Integration: Custom OpenAI / OpenRouter pipelines.
• Fast Frontend: React 19 / Next.js 15 with Tailwind.
• Resilient Backend: Supabase or Node.js.
• User Management: Secure Auth (NextAuth/Clerk).
• Monetization: Stripe integration.
Why work with me?
With a dual background in engineering and UI/UX, I bridge the gap between complex backend architecture and pixel-perfect design. Let’s architect your solution.

Enhancement to PowerPoint 13 & 16
I had the pleasure of working with Regis on my PowerPoint slides, and I couldn't be happier with the results! His attention to detail significantly improved the overall presentation, making it visually appealing and engaging. Additionally, Regis demonstrated impressive Figma skills, which helped elevate our designs further. I highly recommend him for anyone looking to enhance their presentations or design work!

PowerPoint Slides Format Improvement
Regis did an outstanding job with the PowerPoint presentation! His ability to produce high-quality work on such a tight deadline was impressive, especially since he put in extra hours to make it happen. I always appreciate his commitment to revisions, as it adds great value to the final product. You can always count on him to deliver results. Great work, Regis!
