Anay Pandya – Embedded Linux, Automation & Smart Energy Solutions Developer

---

I am a proactive and solutions-driven technologist with a strong foundation in embedded Linux systems, server administration, automation, and energy monitoring systems. With hands-on experience on Banana Pi hardware and real-world applications, I have built secure, scalable, and intelligent systems ranging from mail servers to predictive thermal dashboards.

Projects & Accomplishments

1. Full Mail Server Deployment on Banana Pi

• Built a fully authenticated SMTP/IMAP server using Postfix and Dovecot.

• Achieved 10/10 Mail-tester score with:

  • SPF, DKIM, DMARC DNS validation.

  • SSL certificates from Let’s Encrypt with auto-renewal.

• Configured mail aliases, canonical mapping, and tested with Thunderbird.

2. Apache & WordPress CMS Hosting

• Installed and configured Apache2, PHP, and MariaDB.

• Deployed WordPress for content management and personal web presence.

• Enabled secure database access with custom MySQL users.

• Prepared future CMS integration (HTML/PHP include, iframe support).

3. Smart BHKW Monitoring & Control System

A real-time energy monitoring system for a Blockheizkraftwerk (BHKW) setup using Python, MySQL, and dynamic HTML:

Data Acquisition

• Fetched and processed real-time data from MySQL.

• Converted temperatures from millikelvin to °C.

Thermal Power & Trend Analysis

• Calculated thermal output using temperature deltas.

• Monitored temperature trends over 30-minute windows.

• Estimated engine ON/OFF timing based on thermal gradients.

Forecasting Engine State

• Developed predictive logic to identify whether engine is:

  • Currently running or idle.

  • Likely to switch ON/OFF in the next interval.

Eco Mode Optimization

• Designed an Eco Mode toggle with:

  • Normal thresholds: 54°C (start), 62°C (stop)

  • Eco thresholds: 58°C (start), 60°C (stop)

• Prevented unnecessary starts → reduced fuel & thermal waste.

Energy Saving Estimation

• Calculated potential energy savings in kWh during Eco Mode interventions.

Graphical & Web Visualization

• Plotted trends for Vorlauf, Rücklauf, thermal power, and switching points.

• Created output.png graph and embedded in dynamic HTML dashboard.

• Generated estimation.html dashboard with:

  • Engine status

  • Temperature trends

  • Forecasted actions

  • Savings estimate

  • Eco Mode status

• Web-ready design for iframe or PHP include.

Responsive Dashboard UI

• Designed a clean HTML/CSS user interface:

  • Cards for temperature, engine, and switching time

  • Embedded interactive graph

  • Auto-refresh for live status

4. Tesla Tax Calculation Software Tool

• Developed a custom software tool tailored to calculate EV-related tax liabilities for Tesla vehicle owners.

• Included:

  • Local tax rules

  • Input forms for parameters like Trip time calculation, Trip Kilometers, and Trip classification bassed on user inputs

  • Output estimations based on user inputs

What I’ve Learned

• End-to-End System Deployment on single-board computers

• Smart energy systems with real-time predictive logic

• Importance of email trust & authentication in modern infrastructure

• Full-stack integration from hardware to web frontend

---

What’s Next

• Deploy webmail access (e.g., Roundcube or Rainloop)

• Automate email backups and log rotation

• Package the BHKW monitoring system into a deployable dashboard module

• Build a public showcase portfolio with live demo & GitHub links
