About Me

I am a Full Stack Developer & AI Automation Engineer currently working as SDE 1 at Certus Capital. I specialize in designing high-performance Next.js frontends, resilient Node/FastAPI backends, and advanced AI-agentic pipelines (using LangGraph/LangChain) that automate complex corporate reports and multi-stage decision trees.
