You will get A Full Stack Web App Using React, Node.js & MongoDB
Project details
I engineer automated business assets, not just websites. I am an 8+ year Full-Stack MERN (React, Node.js, TypeScript) expert specializing in high-impact CRM Automation. I deliver seamless, two-way API integrations with platforms like GoHighLevel, HubSpot, and Salesforce. Your custom web app will be fast, scalable, and revenue-driven, automating lead funnels and data sync. Codebase is built on TypeScript, PostgreSQL, and deployed with modern DevOps (Docker/CI/CD). Hire a developer focused on your bottom line.
2. Project Steps
Client purchases the project and sends requirements.
Strategy & Setup: Review requirements, finalize scope (features/APIs), and initialize the Git repo.
Architecture & Core Build: Design database (Mongo/Postgres) and APIs. Build secure Auth and core app structure (React/Node.js).
CRM Automation: Implement custom CRM logic (GHL/HubSpot/Salesforce) for real-time data sync and integrate third-party services.
Testing & Review: Conduct QA/security testing. Provide staging link for client review and incorporate final feedback.
Deployment & Handover: Final launch (Advanced: Dashboard & Deployment pipeline). Full code handover and documentation.

AI Engineer LLM Apps, RAG Systems, AI Agents Python FastAPI Developer
Stamford, United States - 9:46 pm local time
I help startups and SaaS companies turn AI models into real, scalable products using Python, FastAPI, vector databases, and modern LLM frameworks.
My work focuses on building AI systems that understand, retrieve, reason, and act — not just chatbots or prototypes.
🧠 Core AI Expertise
✔️ LLM Applications (GPT-4/5, Claude, open-source models)
✔️ RAG Systems (Retrieval-Augmented Generation pipelines)
✔️ AI Agents (tool-using, multi-step reasoning systems)
✔️ Vector Databases (Pinecone, FAISS, Weaviate, ChromaDB)
✔️ Embeddings & semantic search architectures
✔️ LangChain & LlamaIndex workflows
✔️ Python + FastAPI backend AI systems
✔️ AI API design & integration
⚙️ AI / ML Stack
Python, FastAPI
PyTorch (applied ML workflows)
TensorFlow (model integration & inference)
Hugging Face Transformers
OpenAI / Claude / Azure OpenAI
LangChain, LlamaIndex
Pinecone, FAISS, Weaviate, ChromaDB
PostgreSQL, Redis
Docker, AWS / GCP deployments
🧩 What I Build
✔️ RAG-based knowledge systems (PDFs, websites, databases)
✔️ AI chatbots with memory & contextual reasoning
✔️ AI agents for automation & decision-making
✔️ Enterprise search systems using vector databases
✔️ AI SaaS platforms with full-stack architecture
✔️ Document intelligence & summarization systems
✔️ AI copilots for internal business workflows
✔️ API-based AI integrations for existing products
💼 Engineering Background
