I'm an AI Engineer and Backend Developer focused on building reliable, scalable systems using Node.js, NestJS, TypeScript, MySQL, and modern AI frameworks like LangChain, LangGraph, and n8n.
My work revolves around creating efficient APIs, automation workflows, and intelligent agents that integrate smoothly with real business operations. I've built voice and multimodal AI agents with Vapi and no-code/low-code automation tools. I'm also an official n8n Ambassador, recognized by the n8n team for contributions to the automation community.
I enjoy designing backend architectures that are clean and easy to extend. I'm consistently improving my skills, experimenting with new approaches, and working on projects that push practical AI and backend engineering forward.
Career
From internships to full-time AI engineering — building real-world intelligent systems.
Officially recognized n8n Ambassador — building and supporting the automation community through workflows, content, and knowledge sharing around n8n and AI agents.
Building modern AI engineering pipelines and backend integrations powering production-grade AI workflows.
Built AI voice agent using Vapi, LangChain, n8n to take restaurant orders, integrating real-time data from multiple sources.
Built voice agents with Vapi & LangChain. Connected MySQL, Supabase, and Pinecone for intelligent knowledge retrieval.
Built secure RESTful APIs for the company website using NestJS, MySQL, and TypeORM with Swagger documentation.
Community
Recognized by the n8n team as an official Ambassador — building the automation community through workflows, content, and knowledge sharing.
As an official n8n Ambassador, I represent the fastest-growing workflow automation platform — sharing production-grade automations, AI agent workflows, tutorials, and helping others build with n8n. From voice agents that take restaurant orders to full RAG pipelines, n8n is at the core of how I ship automation.
Selected Work
Production-oriented AI and backend builds — with demos and repositories where available.
Revolutionized social media e-commerce by developing an AI-driven platform that reduced order processing time by enabling customers to order via natural language on Messenger and pay securely with Stripe, eSewa, or Solana Pay. This innovation significantly improved customer experience and operational speed.
Achieved enhanced operational efficiency and data security for companies by building a multi-tenant system with robust role-based access control, allowing secure and streamlined management of inventory, users, roles, and permissions.
Delivered a comprehensive e-commerce platform that boosted sales and user engagement through a full-stack bookstore featuring secure authentication, a dynamic product catalog, efficient cart management, a flexible discount system, FonePay QR payment integration, precise shipping cost calculation, SEO optimization, and intuitive order management.
Built a full-stack AI coding assistant powered by a LangGraph ReAct agent with real-time WebSocket streaming, JWT auth, and isolated per-conversation workspaces. Engineered a custom MCP server (devtoolkit-mcp) exposing 25+ developer tools — file I/O, Git operations, code analysis, shell execution, and HTTP — consumed by the agent via the Model Context Protocol. Supports multiple LLMs (Gemini 2.5, Groq/Llama, Qwen) with a user-side permission gate that requires explicit approval before any tool is invoked.
Built a production-grade MCP server that gives Claude AI autonomous, end-to-end control over MetaTrader 5 — from writing and compiling MQL5 Expert Advisors to running unattended backtests, fetching live market data, and analyzing trade history. Exposes 16 specialized tools across 5 modules (EA manager, backtester, market data, indicators, trade manager), enabling an AI agent to iterate the full write→compile→backtest→analyze loop without human intervention. Backtested an EMA(25/100) + Regime Filter strategy on EURUSD H1 (2024–2026) achieving 7.9% annualized return with only 6.3% max drawdown and a 1.59 profit factor after all broker fees.
Transformed restaurant operations by developing an AI voice agent (Vapi, MCP) that automatically receives customer calls, accurately takes orders, and seamlessly stores them in a database via automated workflows (n8n), resulting in faster service and reduced human error.
Engineered an enterprise-grade, multi-tenant AI voice concierge platform that integrates hotel legacy analog/IP telephony (Asterisk PBX) with Google Gemini's Multimodal Live API. Guests speak naturally with a voice AI by dialing room service, which uses custom tools to log food orders, housekeeping requests, and FAQs in real-time. Features a high-fidelity Next.js staff dashboard with live request queues, real-time guest call transcripts, and strict multi-tenant tenant isolation.
Open Source
A production-grade Roman numeral library with 8 feature categories, published on npm.
Zero-dependency library for Roman numeral conversion, arithmetic, extended numerals (up to 3.9M), Roman clock, Latin words, fractions, React hooks, and CLI. The only package on npm with three unique features no other library provides.
Chrome Extension
My first Chrome extension, live on the Chrome Web Store — it turns any webpage into a Snake game that eats the page's text.
The snake devours the page's actual text character by character — paragraphs first, then headings all the way up to the H1 — with combo multipliers, power-ups, a 90-second time attack mode, four skins, synthesized retro sound, and per-site high scores. Quit anytime and every character is restored exactly as it was.
Yes, really — the snake will eat this portfolio. Best on desktop: steer with arrow keys or WASD, quit from the in-game HUD to restore the page.
Content
Technical tutorials, AI demos, and behind-the-scenes of my projects.
Writing
Deep dives into AI engineering, backend architecture, and automation.
Credentials
Continuous learning, hackathon wins, and technical credentials that prove it.
Feedback from people I've worked with — also visible on my LinkedIn profile.
I'm happy to recommend Tushar Rayamajhi, an outstanding AI Engineer and Backend Developer whom I had the privilege to mentor. His skills in Node.js, NestJS, MySQL, LLM apps, and LangChain are impressive, and he consistently delivers high-quality work. Tushar has shown tremendous growth and even won a national-level hackathon, proving his ability to perform under pressure. As a BCA student in Butwal, he is already operating at a professional level. I strongly believe he will be an asset to any organization.

I've had the privilege of mentoring Tushar Rayamajhi, a BCA student from Butwal Kalika Campus, and he has persistently demonstrated a rare blend of intent, diligence, and inquisitiveness that genuinely distinguishes emerging technologists. He absorbs concepts with remarkable agility, poses incisive questions, and assumes ownership of his tasks without requiring external nudges. Tushar's methodology is grounded in clarity and precision — he dissects complexities into manageable fragments, experiments with purposeful iterations, rectifies inconsistencies with steady resolve, and ultimately produces work that is both polished and dependable. His articulation is lucid, his effort unwavering, and his potential unmistakably expansive. Any team seeking a dedicated, detail-attentive, and ascending technologist would find true value in welcoming him into their fold.
