Over deze dienst

Hi, are you building a Fintech startup, Crypto wallet, Neobank or Payment platform? I develop secure, scalable fintech applications designed for real-world deployment not templates or clone scripts.


This gig covers custom fintech development including digital wallets, custodial or non-custodial systems, payment processing logic, crypto integrations, ledger architecture, admin dashboards and compliance-ready infrastructure.


I focus on security, performance and clean architecture. Whether you need a web-based MVP to validate your idea or a full app + mobile fintech ecosystem with crypto support, I can deliver a structured, production-ready solution.


My Services includes:

  • Secure authentication & user roles
  • Wallet & ledger systems
  • Send/receive & transaction tracking
  • KYC/KYB integration
  • Crypto wallet integration (ERC20/BEP20)
  • API & payment gateway integration
  • Admin dashboard & reporting
  • Cloud deployment support


Every project is built with scalability and compliance in mind.


Please contact me before placing an order to discuss scope, security requirements and architecture.


Looking forward to working with you.
