About

I'm Maya — a full-stack developer and indie maker based in Berlin. I build products that combine hardware-aware backends with polished frontends: MQTT dashboards for IoT fleets, Flutter apps with NFC flows, and AI APIs that stay grounded in real data. **What I care about:** shipping fast, writing clearly, and leaving a trail of public work so recruiters and clients can see momentum — not just a static portfolio.

MQTT Dashboard v2 3

MQTT Dashboard v2

Production MQTT dashboard for fleet operators — live telemetry, alert rules, and exportable reports built with React and WebSockets.

ReactMQTTIoT

Role. I designed and built the dashboard.

Result. Fleet operators could watch device health and alert rules in one view.

Written by the profile owner. Not independently verified.

Case study

Problem

Operators were checking device health across separate tools.

Context

A fleet team needed live telemetry and a way to export reports.

Role

I owned the React dashboard and the alert rules.

Approach

WebSockets for live readings, with alert rules the operator can edit.

Result

The team watches the fleet from one screen and exports the reports they used to assemble by hand.

Published by the owner. Empty sections were left out because the notes did not cover them.
