Backend & Solana Engineer focused on building systems, developer tooling, and production-grade blockchain applications.

Co-founder · Privacy-focused payment system (Solana)

A payment system designed to balance privacy with compliance, while introducing incentives for both users and merchants.

• Privacy-focused transaction design with compliance considerations
• Incentive model rewarding users and merchants
• Built for reliability, smooth execution, and real-world usage
• Currently under active development

Backend framework (TypeScript, Web Standard APIs)

A backend framework built around correctness, composability, and predictable behavior.

• Built on Web Standard APIs — not tied to a specific runtime
• Supports modern runtimes like Bun (Node and others in progress)
• Clean middleware system for request flow control (logging, auth, etc.)
• Relic system for explicit, type-safe contracts between layers
• Fails invalid configurations at startup instead of runtime
• Custom Radix tree router for efficient route matching
