I am Yahya Firdaus, a backend-focused software engineer with experience in building reliable web systems, data workflows, dashboards, chatbot products, and AI-assisted analytics tools. My strength is combining practical backend engineering with data and AI product thinking, so I can build systems that are not only functional but also useful for business operations. I have worked with Django, Flask, PostgreSQL, Docker, Next.js, and Python-based data tools, and I am looking for a Backend Developer, Data Engineer, or AI product-related role where I can contribute to scalable, reliable, and practical digital solutions. https://portofolio.axentraproject.site/
