Fintech, tokenization, wallet, and Web3 engineering
I build product features and backend systems for financial workflows, digital assets, tokenized products, wallets, marketplaces, and Web3 applications using TypeScript, Node.js, NestJS, React, Next.js, PostgreSQL, AWS, Docker, and related integrations.
Good fit for
• Financial products and payment-enabled platforms
• Tokenization, wallet, NFT, and digital-asset workflows
• Marketplaces, dashboards, account systems, and transaction-oriented APIs
• Existing products that need a senior engineer for architecture and delivery
Relevant delivery experience
I have worked on loan securitization and tokenization infrastructure, multi-chain wallet platforms across Bitcoin, Ethereum, and BNB Chain, tokenized precious-metals products, NFT gaming, payments, onboarding, and financial utilities.
What you can expect
