01Background & working style

A full-stack engineer who owns the whole system

→ Disciplines

I build the systems businesses actually run on — payment and wallet backends, a fintech trading platform, admin dashboards, and the deployment pipelines that keep them online. I care about the screens people touch and the reliability underneath them.

I have 3.7 years of production experience across Java and the MERN stack, and I lead the engineering team at Algofolks. I set technical direction, design the systems, own deployments on AWS, review the code that ships, and mentor the people writing it.

I do my best work owning the messy middle: designing the architecture, building it end to end, keeping it alive in production, and bringing a team along with me.
