About

From zero-to-one builds to scaling enterprise platforms.

I use AI to accelerate development, automate repetitive tasks, and surface insights — staying focused on strategy, quality, and architecture. Equally comfortable driving architecture decisions and shipping features, with a track record of aligning engineering delivery with product, design, and business goals.

I aim to map every project with the objectives first, timelines locked and documentation in order to build clean and scalable systems. I have expertise in IaC and both mobile and web development.
