About me
|Who I am?
Hey, I'm Mohammad Rana Arju — a Full Stack Developer & AI/ML Engineer at Saskit with 4+ years of experience shipping production web apps and intelligent automation systems. Beyond client work, I'm the founder of BloodNeed, a platform connecting voluntary blood donors with people in urgent need, and ReplyTentra, a B2B agency building AI agents, workflow automation, and custom software for growing businesses. I work across the stack — React, Next.js, Node.js, Express, MongoDB, PostgreSQL — and increasingly with AI/ML tooling like TensorFlow and PyTorch, and automation platforms like n8n, Zapier, and GoHighLevel.
