Ravi S.

I build AI agents, blockchain platforms and full-stack web products that actually ship to production - not prototypes. Over the past 9 years I've worked on government-scale systems, fintech and tokenization platforms, and e-commerce stores, as part of Ment Tech Labs and independently. The common thread: products that handle real users, real money and real compliance. What I build - • AI agents and LLM applications - RAG pipelines, agent workflows with human approval, document intelligence, chatbots and voice agents (OpenAI, Anthropic, LangChain/LangGraph) • Blockchain and Web3 - smart contracts (Solidity), RWA tokenization platforms, DeFi modules, wallets, crypto payment and stablecoin rails, exchange front-ends • Full-stack web - React / Next.js, Node.js / NestJS, Python, PostgreSQL, MongoDB; REST and GraphQL APIs; Shopify and WordPress for commerce • Product delivery - I've run projects end to end as product owner and PM, so I write clear specs, communicate progress daily and don't need hand-holding Work I've shipped (team and solo) • National Tax Portal, AI tax-fraud detection system and Appeals Management Platform for a government client - AI agents with strict access control and full audit trails, under a five-year contract • Real-estate tokenization platform with fractional ownership, investor wallet and KYC onboarding • AI banking agents for fraud checks, KYC and customer support • D2C Shopify store plus ERP and field-sales mobile app for a dermatology brand - payments, logistics, SEO and analytics integrated • Crypto exchange and digital/crypto banking platform front-ends How I work - Daily updates, clean documented code, staging before production, and honest estimates. If something won't work the way you want, I'll tell you before you spend money on it. Available for hourly and fixed-price projects. Send me a message with what you're building and I'll reply within a few hours with questions, not a sales pitch.
