>Initializing bio sequence...
I am Hein Tay Zar (Tay Za)—a systems architect and startup builder currently pursuing my ICT degree at Rangsit University, Thailand. Operating at the intersection of emerging digital economies (Myanmar) and mature tech hubs (Thailand), I design and deploy production-grade fintech architectures and zero-trust applications.
>Active Operations & Ventures:
>Loading core directives...
Mitigating race conditions and enforcing absolute database-level atomic operations (increment/decrement RPCs) for fintech workloads.
Implementing serverless edge function execution and strict Row-Level Security (RLS) policies to prevent client-side rate or state spoofing.
Validating and shipping ideas fast using modern stacks (Next.js App Router, Supabase, Vercel Edge, and Agentic RAG integration).
