Ashutosh Sahu

Fastliq Solutions Pvt. Ltd.

• Owned the backend API layer end to end on a live client project, building 12+ REST endpoints in Node.js, Express.js and MongoDB over a 2-month internship.
• Drove one shared API contract consumed by both the web frontend and the mobile app, so 2 client-facing products were served from a single backend.
• Designed the MongoDB data models and the REST resource structure behind that contract.
• Worked with the web and mobile developers to settle endpoint schemas, authentication and error handling.

Node.js, Express, React, LangGraph, LangChain, Redis, API Gateway, Firebase, Razorpay

• Architected a distributed, multi-tiered microservices backend of 5 services: Gateway, Auth, Agent, Chat and Billing, with an API Gateway and Redis rate limiting.
• Built a LangGraph and LangChain orchestration engine where a supervisor agent coordinates 4 specialist agents for coding, vision, document parsing and web search.
• Integrated 4 model providers, Google Gemini, DeepSeek, Groq and OpenRouter, so each request can be routed on cost, latency and quality rather than being pinned to one vendor.
• Wrote tests for the service endpoints and checked code quality across the 5 service boundaries.
• Built the React frontend with an artifacts panel, Firebase authentication and Razorpay subscriptions.

MongoDB, Express.js, React.js, Node.js, Redux Toolkit, Socket.IO, React-Leaflet, Google Gemini API, Tailwind CSS, JWT

• Built a multi-vendor platform supporting 5 user roles on secure REST APIs, with JWT-based role-based access control deciding what each role can reach.
• Implemented live delivery tracking and customer support using React-Leaflet for the map and Socket.IO for the updates.
• Designed the admin dashboard on MongoDB aggregation pipelines, covering analytics, restaurant approval and moderation.
• Added a Google Gemini chatbot that resolves common customer queries without a human in the loop.
• Wrote tests and checked code quality across the API surface.
