I build backend systems for financial and crypto platforms where failures have real consequences.

15+ years in backend and platform engineering.
Last 5+ years focused on crypto infrastructure, trading systems and transaction flows.

• Trading and financial infrastructure
• Blockchain integrations and wallet systems
• Transaction processing and high-load APIs
• Systems with strict invariants, consistency and predictable behavior

Crypto trading system.

• Designed and implemented core backend architecture
• Built session-based accounting with explicit risk isolation
• Responsible for production behavior and system reliability

Self-custodial crypto wallet.

• Designed wallet architecture and transaction flows
• Implemented separation between key management, signing and execution

• dxs-stas-sdk
  TypeScript SDK for working with Bitcoin SV transactions and STAS tokens

• dxs-consigliere
  Blockchain indexer with real-time updates and Back-to-Genesis resolution

C# / .NET • TypeScript • PostgreSQL • RavenDB
Docker • Kubernetes • GitHub Actions
Blockchain RPC (Ethereum, TON, TRON, Polygon, BSV)

Backend-first engineer with strong system design background.
I prefer small teams, fast iteration and building production systems end-to-end.

Comfortable across the stack when needed (TypeScript / React), but focused on backend, infrastructure and reliability.

Open to roles in:

• Crypto infrastructure
• Trading systems
• Fintech / payments
