Malamin Jagana
About Me
Senior Full-Stack Developer & AI Engineer with 6+ years of experience delivering scalable, production-grade applications for startups, enterprise clients, and international companies. I specialize in building high-performance web systems, integrating modern AI workflows, and solving complex technical challenges with clean, reliable engineering.
I build solutions for the translation and localization industry, helping translators, language service providers, and multilingual teams streamline their workflows through AI-assisted translation, intelligent terminology management, automated quality assurance (QA), document processing, CAT tool integrations, and LLM-powered language workflows. My solutions reduce manual effort, improve consistency, accelerate project delivery, and enhance translation quality while keeping humans in control.
I’ve worked across FinTech, Energy, E-commerce, Education, Healthcare, and Localization, consistently improving performance, reliability, and user experience. Fluent in English, German, and Arabic, I collaborate effectively with cross-functional teams and international clients.
Strong focus on quality, security, automation, scalable architecture, and long-term maintainability.
