Hillol Das Pias
@hilloldaspias
I build AI-powered full-stack products with LangGraph, Next.js, FastAPI, and human approval workflows.
BangladeshWhat I'm looking for
I've shipped AI-agent products including Support Ops Copilot, a LangGraph customer-support system that blocks customer-facing actions until human approval, and Ledger, a ReAct-style task manager with 17 tools, RAG search, and LangSmith tracing.
At SwaPE IT Solutions, I build production web applications with Next.js, React, Node.js, and FastAPI, lead system-design decisions, and integrate OpenAI and Google Gemini into client-facing product flows. Previously at Raj IT Solutions, I built REST APIs, real-time Socket.IO features, Strapi CMS solutions, and Docker-based CI/CD pipelines.
I also deliver e-commerce and booking systems with Stripe, scalable SQL and NoSQL databases, and containerised deployments. My earlier graphic-design experience strengthens the visual communication and frontend UI work I bring to full-stack products.
