ABOUT MOSTAFA IBRAHIM
Most SaaS companies hire writers to create technical content. The problem? Those writers have never shipped production code. The result is tutorials with broken examples, blog posts that senior engineers see through in 30 seconds, and documentation that hurts more than it helps.I am a software engineer who writes technical content for B2B SaaS and AI companies. I have shipped code at GoCardless and Arm, researched Generative AI at the University of Oxford, and written 200+ technical articles that have reached readers.Companies I have written for include Weights & Biases, SuperTokens (YC S20), Ultralytics, Civo, and Zilliz - covering topics from Kubernetes deployments to RAG systems to authentication flows.What makes my content different: every code example compiles, every tutorial has been tested, and every explanation is written by someone who understands the engineering underneath.If you need technical content that developers actually trust, let us talk: mostafa.moqbel.ibrahim\"gmail.com* Top AI writer on medium, 500k views, https://medium.com/@mostafaibrahim18Profiles:1.
