I like the point where software stops being only software.

I build practical systems that connect code, hardware, data, networking and visual design — from ESP32/Arduino devices and sensor networks to Python tooling, dashboards, automation, APIs and 3D workflows.

My favorite projects are the ones that solve a real problem, survive real-world constraints, and can be improved over time.

A resilient, multi-node IoT platform: ESP32 sensor nodes and an Arduino-based RFID door-access node work together, log to SD storage, sync to a local dashboard, and keep working even when the network drops.

architecture:
  master:
    - ESP32 / ESP32-S3
    - SSD1306 OLED status display
    - DHT22 temperature & humidity sensing
    - Wi-Fi + GitHub Pages sync
  slave:
    - Arduino UNO
    - MFRC522 RFID reader
    - Relay-driven door / lock control
  data:
    - SD card CSV logging
    - Historical readings
    - Downloadable records
  interface:
    - Local dashboard with charts
    - Auto-recovery on node / network failure

Dual-node environmental monitoring: DHT22 sensors feed a live web dashboard and an on-device OLED, with SD card logging and historical charts for offline review.

hardware:
  - ESP32 (dual-node)
  - DHT22
  - SSD1306 OLED
  - MicroSD
software:
  - Wi-Fi
  - web dashboard with historical charts
  - local + remote data logging

A single-file, Jalali/Shamsi-calendar-aware web tool that calculates overdue license-renewal penalties — overdue months × monthly fine, plus the fixed renewal fee — behind a responsive, modern neon interface.

focus:
  - network diagnostics
  - automation
  - data processing
  - desktop utilities
  - CLI tools
  - error-tolerant workflows
  - exportable reports

A visual portfolio for projects, technical interests and a developer identity.

This section is generated by lowlighter/metrics, the repository that powers the profile analytics layer. The current Metrics release line exposes a large plugin ecosystem, including isometric calendars, languages, achievements, habits, notable contributions, activity and repository views. Full plugin documentation: lowlighter/metrics.

The achievement panel is generated directly by the Metrics achievements plugin, rather than a manually maintained trophy image. The official plugin supports compact/detailed displays, filters and thresholds; this setup keeps the data dynamic and repository-local.

The snake is intentionally a separate visual layer: Metrics handles analytics, while the local SVG keeps the animated contribution-wall effect lightweight and easy to maintain.

now:
  - Advanced ESP32 development
  - Reliable IoT device communication
  - Better API and backend architecture
  - Docker and self-hosted automation
  - Professional 3D workflows
  - Building stronger open-source projects

next:
  - Production-ready IoT platforms
  - More reusable developer tools
  - Better observability and testing
  - Independent technology products
  - More public documentation
