Backend & Integration Engineer
Before I wrote software, I sat in a NOC watching other people's systems fall over at 3 in the morning. That taught me what "it works on my machine" actually costs — and it's why I still think about how a system fails before I think about what it does.
Since then most of my time has gone into the parts of e-commerce nobody demos: order pipelines, marketplace APIs, message queues. At Jubelio I rebuilt the store platform on RabbitMQ and got new-site provisioning down to under 15 minutes. At JavaMifi I wired six marketplaces into a single automated order flow — it started at 87% of the manual typing removed, and it now handles all of it.
On the side I run CashPlay, a digital top-up platform I built and still operate, and I teach SQL at SQLMaster.
No percentage bars. Nobody can say what 90% of JavaScript means.

I have a full-time role, but I take on a small number of projects outside it — usually the kind that involve marketplaces, order flows, or a manual process that has outgrown its spreadsheet.
Connecting Shopee, Tokopedia, TikTok Shop, WooCommerce, Ecwid or Traveloka to whatever you already run. Webhooks, stock sync, order ingestion, and the edge cases none of the docs mention.
Finding the work your team retypes by hand every day, and making it stop being their job.
Node.js or Laravel services, message queues, and database design for systems that have to stay up.
Inheriting code someone else wrote, understanding it, and getting it moving again. I have done this more often than greenfield.
A marketplace integration that keeps breaking, a process your team still does by hand, or a system someone left behind that needs picking up — those are the three I enjoy most. Email is fastest; I usually reply within a day.
