The Engineer
I am a Backend-focused Software Engineer specializing in architecting scalable, multi-tenant SaaS platforms using Node.js (NestJS) and TypeScript.
I bridge the gap between legacy reliability and modern scalability. My deep expertise lies in building high-availability APIs, event-driven architectures, and immutable financial ledger systems.
Unlike many developers who focus solely on features, I focus on system integrity. Whether it's ensuring 99.8% payment success rates via idempotent webhooks or implementing granular Permission-Based Access Control (PBAC), I build software that businesses can rely on.
