David Coulibaly
About this gig
Stop losing sales to slow, insecure websites.
I am an Engineering Student and Research Intern at LAAS-CNRS (Cloud & AI). Unlike generic designers who use heavy templates, I build custom, high-performance Web Applications and E-commerce Stores designed to scale.
My Engineering Approach:
- Next-Gen E-commerce: Blazing fast shops (Next.js) with secure payment gateways (Stripe/PayPal) and inventory management.
- SaaS Platforms: Complex web apps with User Dashboards, JWT Authentication, and Admin Panels (similar to my work for Kreativ Academy).
- Corporate Sites: SEO-ready, mobile-first, and animated (Framer Motion).
Why trust an Engineer?
- Bank-Grade Security: I implement OWASP standards to protect your customer data and payments.
- Speed = Sales: My architectures are optimized for Google Core Web Vitals (100/100 Score).
- Scalable: Ready to deploy on AWS or Vercel to handle traffic spikes.
Tech Stack: React.js, Next.js, Tailwind CSS, Node.js, PostgreSQL, Docker.
Launch Offer: I am offering premium engineering services at a discounted rate to build my Fiverr reputation. Order now before prices go up!

FAQ
Why should I choose a custom Next.js site over WordPress?
WordPress can be slow and vulnerable to hacking. A custom Next.js site is static, ultra-fast (better for SEO), and much more secure against attacks. It's the standard for modern startups in 2026.
Is the payment system secure for my customers?
Absolutely. As a CyberOps certified engineer, I integrate Stripe or PayPal using strict security protocols (SSL/TLS, PCI compliance) to ensure all transactions are encrypted and safe.
Will my website be mobile-friendly and SEO optimized?
Yes. I use "Mobile First" design principles. Your site will look perfect on all devices. I also implement Server-Side Rendering (SSR) with Next.js, which Google loves for ranking.
Can you deploy the site to my own Cloud server (AWS)?
Yes! Unlike simple designers, I have Cloud orchestration expertise (LAAS-CNRS). I can deploy your app on AWS, DigitalOcean, or Vercel for maximum performance (check Gig Extras).
Do you provide support after delivery?
Yes. I provide 2 weeks of free support to fix any bugs. For long-term maintenance or updates, we can discuss a monthly retainer.
