Profile

Backend-oriented developer with strong focus on service design, typed contracts, idempotency, authentication flows and production hardening.

I work primarily with Node.js + TypeScript and Go, designing APIs and systems with:

• Clear domain modeling
• Explicit contracts
• Idempotent operations
• Observability and resilience
• Secure-by-default practices

I approach FullStack from a systems perspective: frontend is a consumer of well-designed services, not an afterthought.

Current Focus

• Auth systems (self-hosted, ORM-first)
• API design and middleware architecture
• Idempotency strategies and request safety
• CI/CD pipelines and production deployments
• Security hardening and runtime reliability

Active Project:

• GoPotency — A flexible, framework-agnostic Go package for handling idempotency in HTTP APIs.
