Chaikh Najjarine

I write software that has to work — not just demos, but the systems freight forwarders rely on at 3 a.m. Clean architecture, SOLID principles, and code that the next person can actually read.

Currently shipping enterprise data integrations for the German freight-forwarding industry at Fixemer Telematik. Previously: NestJS / Strapi / Laravel across Lebanon, the US, and remote teams.

※ The setup

I'm a full-stack developer who splits time between enterprise data plumbing and the kind of customer-facing UI that has to actually work on a logistics dispatcher's screen at 4 a.m.

Full-stack developer with 4+ years of experience building production web applications across the JavaScript and PHP ecosystems. Proven track record shipping REST APIs, integrations, and responsive frontends with Node.js, Next.js, React, Laravel, and SQL/NoSQL databases. Currently delivering enterprise data-integration and frontend features at a German logistics-tech company.
