Chennai, India - 2:19 am local time
Two of my live products:
haxswap com (crypto P2P exchange) and b4bwallet com (Web3 wallet) — both built from scratch and running in production today.
If you need clean code, fast delivery, and someone who takes ownership — that's exactly how I work.

Admin Dashboards & SaaS Platforms:
Data tables, analytics dashboards, role-based access, real-time updates, scalable architecture
AI Integration & Automation:
OpenAI API, Claude API, LangChain, RAG systems, AI chatbots, document Q&A platforms, workflow automation
Blockchain & Web3:
Smart contracts (Solidity), CEX/DEX/P2P exchanges, DeFi platforms, wallet integration, ERC20 tokens, DApps, RWA, Assets Tokenization

REAL PRODUCTION EXPERIENCE
Built and deployed haxswap — a live crypto exchange with P2P trading, real-time order processing, USDT/TRC-20 support, and wallet integration.
Built b4bwallet — a production Web3 wallet with multi-chain support and secure transaction handling.
Built a full AI RAG chatbot platform — PDF/DOCX/CSV uploads, GPT-4 grounded answers, vector search using pgvector, deployed with Docker and FastAPI.
Worked on a Dubai-based crypto exchange backend — P2P trading engine, fund flow architecture, real-time transaction processing, financial-grade security.

Steps for completing your project
After purchasing the project, send requirements so Ranijth can start the project.
Delivery time starts when Ranijth receives requirements from you.
Ranijth works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Requirement Analysis
We begin with a deep dive into your business goals. I analyze your target audience, functional requirements, and technical constraints to create a solid Product Requirement Document (PRD). This ensures we are perfectly aligned.
Architecture & UI/UX Design
I design the Database Schema (MongoDB) and system architecture for maximum scalability. Simultaneously I create wireframes or high-fidelity prototypes using Tailwind CSS/Material UI to map out the user journey and ensure a modern, intuitive interface
