About me

I'm a developer based in Serbia who bridges the gap between physical hardware and cloud software. My specialty is building complete IoT systems — from wiring sensors and microcontrollers to writing the backend API and the real-time dashboard.

My flagship project, GrowMind AI, is a smart grow box platform with live camera streaming, environmental sensors, and an AI supervisor — built from scratch, currently preparing for Kickstarter launch.

I also have experience with MetaTrader 5 (MQL5) Expert Advisors, automated trading systems, and algorithmic strategy development.

The challenge

Traditional grow boxes use dumb timers. When something goes wrong — heat spike, humidity drop, light cycle issue — the grower finds out too late. There's no visibility, no history, no intelligence.

The solution

I built a complete platform: ESP32 reads sensors and controls fans/LEDs, Raspberry Pi streams a live camera and pushes telemetry to a PHP cloud backend. An AI layer (Ollama + RAG) provides grow recommendations with human approval.

Tech stack used

Raspberry Pi ESP32 PHP 8 MariaDB REST API Chart.js PWA Ollama AI Firebase FCM DS18B20 Live Camera RBAC

Key features I built

CAM
Live camera streaming

Auto-refreshing snapshots from Pi camera, served via API with timestamp overlay

LOG
Sensor telemetry & graphs

Temperature, humidity, pH, EC — full history with Chart.js visualization per box

AI
AI supervisor with RAG

Local Ollama LLM + plant knowledge base, automated recommendations with owner approval

IOT
Edge + cloud control

ESP32 handles local sensor reads and relay control; cloud sends commands via API

USR
Multi-role user system

Admin (factory), owner (buyer), viewer — with activation codes and box claiming

PWA
Progressive Web App

Installable on mobile, push notifications via Firebase, offline-capable service worker
