You will get a Scalable Node.js Backend with AI Integration
Project details
Build a robust foundation for your app with a Scalable Node.js Backend and MongoDB. As a specialist in event-driven architecture, I deliver high-performance APIs capable of handling massive concurrent traffic. Using Node.js (Express/NestJS) and NoSQL MongoDB, I ensure your data layer is both flexible and lightning-fast.
What’s Included:
RESTful/GraphQL API development; modular architecture.
MongoDB schema design, indexing, and performance tuning.
Secure Authentication (JWT, OAuth2, Bcrypt).
Cloud deployment (AWS/Heroku) with Docker support.
Why this project?
I focus on "clean code" principles to ensure your backend is easy to maintain and scale. Whether it's a real-time chat or an e-commerce engine, you get enterprise-grade infrastructure.

SEO Optimization Agent Build
This was a very negative experience working with the freelancer due to the following reasons:
1. Upon the completion of our project, we were delivered code that had the presence of a malicious remote-code-execution (RCE) payload hidden in run.py. This type of code is malware designed to sneakily download and run other harmful programs on our systems to steal credentials or take control of the server.
2. The malicious code was not added by an outside hacker. Our review showed that this harmful code was included inside a normal, structured update that the freelancer created and submitted under their own name. This strongly suggests it was a deliberate action, not a random hack
3. After we requested a refund, the freelancer "rewrote" the project's history in the repository to completely remove the evidence of the malicious code. This action destroyed the reliable record of all changes, making it impossible to fully verify the prior state of the code.
Because the code contained malware and the freelancer then destroyed the history to hide it, we cannot trust any of the delivered work. The entire project is compromised and must be completely rebuilt. This means the delivered work had zero value to us, which we were unable to recoup as the Freelancer refused to given us a refund.

Job Success
Milton, Canada - 7:23 am local time
I design and deliver AI-powered full-stack applications and enterprise-grade infrastructure that automate workflows, cut operational costs, and unlock new revenue streams.
With 10+ years of software engineering experience and 90+ successful production deployments, I partner with startups and enterprises to ship AI systems that actually run in production , not proofs-of-concept that look great in a demo and break the moment real users hit them.
Business Problems I Solve:
Most AI projects fail not because the model is wrong, but because the system around it is. Here's where I deliver measurable impact:
Reducing operational inefficiencies by embedding AI into daily workflows and automating repetitive tasks
Fixing scalability bottlenecks with cloud-native architecture built for high-volume data and real-time decisioning
Eliminating integration headaches by connecting CRMs, ERPs, and SaaS tools through secure, production-ready APIs
Improving reliability and accuracy of AI systems through fine-tuning, RAG pipelines, and rigorous evaluation
Cutting costs and accelerating time-to-market with optimized workflows and reusable AI infrastructure
Unlocking new revenue through customer-facing AI agents, voice assistants, and intelligent automation
What I Build for Clients:
AI-Powered SaaS Platforms — From MVP to scalable production on Next.js, FastAPI, and modern cloud infrastructure.
AI Chatbots and Voice Assistants — Deployed across WhatsApp, Instagram, Telegram, Facebook, websites, SMS, and IVR.
LLM Agents and Multi-Agent Systems — Autonomous agentic workflows using LangChain, LangGraph, CrewAI, and AutoGen.
Enterprise RAG Systems — Chat-with-data and knowledge-base systems on Pinecone, Qdrant, Weaviate, ChromaDB, and FAISS, engineered for zero-hallucination accuracy.
Workflow Automation and AI Orchestration — n8n, Make, Zapier, and Pipedream pipelines bridging your CRM intelligence with LLM reasoning. Native integrations with HubSpot, Salesforce, Zoho, GoHighLevel, and Shopify.
Custom APIs and Backend Systems — FastAPI, Flask, Django, and Node.js services built for reliability, observability, and scale.
Modern Full-Stack Apps — React, Next.js, and TailwindCSS frontends connected to robust AI backends.
