Senior Full Stack Web3 Developer | Next.Js, Wallets, Dashboards, Marketplaces
I am a Senior Full-Stack Web3 Developer focused on building credible, production-ready platforms for serious teams.
My work combines product thinking with full-stack engineering. I build Next.js frontends, NestJS backends, PostgreSQL/Prisma architectures, SaaS dashboards, admin panels, marketplaces, wallet flows, crypto payment systems, token launch interfaces and smart contract frontend integrations.
I focus on products that need clarity, trust, maintainability and strong execution. Web3 products often fail because the user flow is confusing, the transaction experience is stressful and the architecture is fragile. My role is to turn that complexity into a platform users can understand.
Strongest areas: Web3 dashboards, dApp frontends, wallet flows, crypto payment UX, token launch interfaces, marketplace architecture, SaaS/admin systems, smart contract frontend integration, Next.js / NestJS / PostgreSQL architecture.
Current work: CryptoFunders (Web3 fundraising infrastructure + CFT token), TrueSwapMarket, EclipseX, Immolityx.
