Sayan Das

I’m an AI Automation Architect and Developer specializing in AI orchestration, agentic workflows, and advanced prompt engineering. I focus on turning complex ideas into scalable digital solutions—spanning custom web platforms to autonomous agents designed for global enterprise deployment.

I build, train, evaluate, and localize complex large language models by combining deep technical training with rigorous prompt optimization frameworks. I also bring multilingual native/professional proficiency across English, Hindi, Kannada, and Bengali to improve real-world usability.

In my hands-on work, I’ve built multi-agent architectures with LangChain, designing continuous autonomous loops evaluated and optimized inside the Antigravity AI IDE environment. I also created production-ready conversation flows using state-machine configurations to reduce text-to-speech latencies and strengthen localization performance.

I’ve complemented my agent work with data and marketing optimization—conducting 69 hours of structured Excel development for advanced analytics modeling and applying AI-driven ad campaign architectures to optimize conversion paths and traffic modeling parameters. I’m driven by measurable outcomes: evaluate, iterate, and ship reliable systems.
