About Me

Building systems where correctness isn't optional

I'm a Senior Software Engineer with 7+ YOE building high-volume, correctness-critical systems — the kind where a race condition or a lost transaction isn't a bug, it's a real problem for real users. I work across the stack, but my center of gravity is backend architecture and the data-consistency problems that come with scale.

Payments

My specialization is payments. At Fazz Financial Group, I worked on QRIS and e-wallet infrastructure processing high volumes of latency-sensitive transactions:

  • Solved for idempotency, race conditions, and authorization flows on transaction-critical paths
  • Ensured ledger consistency under concurrent transactions using row-level locking, unique constraints, and idempotency keys

E-commerce & Logistics

More recently at HubOn & HubShop, I've broadened into architecture ownership across e-commerce and logistics:

  • Designed and built marketplace search on Meilisearch with Sidekiq-driven async indexing
  • Proposed and drove the decision to build our HubShop platform inside the existing backend, with clean internal separation for future flexibility
  • Resolved race conditions in critical concurrent workflows — same correctness discipline, different domain

I care about the tradeoffs behind the code — data consistency, system reliability, architecture decisions, and choosing the right tools for the problem. My goal is to build systems that remain fast, reliable, and secure when they matter most.
