Back to original languageAbout Hamadi
⚡️ Senior Web Developer | Front-End – Back-End – Applied AI
I assist startups, SMEs, and large corporations in creating MVPs, modern SaaS applications, and intelligent products.
With 12 years of experience, I design high-performance interfaces, robust APIs, and integrate AI into the core of business tools.
🎨 Modern Front-End
I build modern, fast, and scalable interfaces:
• React / Next.js 14+, Server Components, SEO, performance
• TypeScript, UI/UX, design systems (Storybook, Tailwind, Chakra)
• State management: Zustand, Redux Toolkit
• Pixel-perfect integration from Figma / XD
👉 Ideal for MVPs, SaaS, dashboards, and products requiring polished UX.
🛠️ High-Performance Back-End
• Node.js / Express / Nest, Python / FastAPI, PHP
• Stripe payments, invoicing, webhooks, transactional emails
• Auth (JWT, OAuth2), webhooks, automation, lightweight CI/CD
• SQL / NoSQL, clean and maintainable architectures
👉 From simple backends for MVPs to robust APIs for SMEs and large corporations.
🧠 Artificial Intelligence (my added value)
I integrate real AI features into products:
• Autonomous agents (OpenAI, LangChain, LlamaIndex)
• Multi-agent workflows and business automation
• RAG: vector DB (Elasticsearch, Chroma, Pinecone)
• AI assistants & business copilots
👉 I transform a classic tool into an intelligent and truly useful application.
💎 What sets me apart
I master the entire chain: Front + Backend + AI.
Result: a coherent, modern, maintainable, and scalable product.
I have supported 30+ projects (startups, SMEs, large corporations) with a clear approach: clean code, best practices, simple communication, and efficiency.

Website page to be hosted on the hosting of the other pages of the site, there was a cache problem that prevented proper functioning, problem resolved and transition to HTTPS, another part of the project also successful. If there were issues with deadlines and communication, it's more on my side for not being able to express the request well.
