About Mohamed Salah

With 10 years of experience in Fullstack development, I have built solid expertise covering the entire application lifecycle: designing scalable architectures, developing high-performance web and mobile applications, and deploying cloud-native infrastructures on AWS, GCP, and Azure. Accustomed to demanding environments, I am proficient in setting up robust CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins) and associated DevOps practices — Docker containerization, Kubernetes orchestration, observability, and Infrastructure as Code with Terraform.
On the technical stack side, I navigate equally well on the front-end (React, Next.js, TypeScript) as on the back-end (Node.js, DotNet, PHP, microservices architectures, and REST/GraphQL APIs), with particular attention to code quality, automated testing, and application security.
I have had the opportunity to work in various sectors — education, e-commerce, media, digital marketing — which has taught me to adapt quickly to business constraints and translate complex needs into concrete technical solutions.
For the past few years, I have been actively interested in the rise of AI and its integration into modern applications: fine-tuning LLMs, RAG (Retrieval-Augmented Generation), integration of APIs like OpenAI or Anthropic, and automation of workflows through AI agents. I am convinced that developers who can combine rigorous software engineering with mastery of AI tools will have a decisive advantage in the coming years — and this is precisely the direction in which I am orienting my expertise.
