Engineering products from database to screen

I build full-stack web products end to end: the schema, the API, and the interface on top. Currently an Associate Software Engineer at Arkmind. Before that, ML forecasting and industrial IoT telemetry.

About

Beyond the CV

Most of my work is TypeScript and Python across the stack, and the builds I enjoy most are the ones where I own the schema, the API, and the screen. I came to it sideways, through a final year project on time-series forecasting and an internship building industrial IoT pipelines, which is why I am comfortable when the data layer turns out to be the hard part.

I think AI-assisted development is becoming the default way software gets written, not a novelty on top of it. Driving it well is its own skill: framing the problem, giving the model the right context, building the harness around it. I am still learning it, deliberately rather than by accident.
