Software Engineer with 3+ years building backend systems, cloud infrastructure, and full-stack applications. I've shipped across SaaS, FinTech, identity/auth, and IoT, and have integrated AI and blockchain capabilities into products when the problem called for it.

I work across the full delivery lifecycle, from technical discovery and architecture through to deployment and iteration. I care about understanding the problem before writing code, and I measure my work by the business outcomes it drives.

Currently going deeper on distributed systems, backend architecture, and auth/identity protocols.
