I'm a Full Stack Software Engineer with experience building production applications across frontend, backend, cloud infrastructure, DevOps, and AI. I've worked in fast-paced startup environments, including leading the development of an AI SaaS product and collaborating closely with technical and business teams. I enjoy building products from scratch, solving challenging problems, and continuously learning new technologies.
