I don’t just work with data — I automate it, scale it, and build the future with it. 👋 I’m Sayantan Ghosh — a bold technologist who thrives at the intersection of Backend Automation, Data Engineering, and GenAI. 🧠 With experience across Big Data ecosystems (Hadoop, Hive, PySpark), ETL pipelines, SQL/NoSQL systems, and Azure-based cloud solutions, I specialize in architecting high-performance, low-maintenance systems. 🔄 I live by a simple mantra: “Why do it twice when you can automate it once?” 💡 I'm building agentic AI tools, sharing free resources, and actively mentoring devs breaking into tech. My focus is on community, contribution, and cutting-edge innovation. ✅ What sets me apart? 🧩 Strong grip on DSA & systems thinking 🛠️ Backend pipelines that don’t break 🧪 Constant GenAI experiments (LLMs + Agents) 🔓 Free stuff for learners (PDFs, courses, tools) 🤝 DMs open for Referrals & collabs 📜 Patent Holder | 🎤 Tech Speaker | 🧑‍🏫 Open Source Contributor 💬 Let’s build something legendary → Connect now or DM for a collab.
