Offline Logger (M-Kris Electric)

• Offline logger software for Windows OS using python, react, CSS, html, MySQL. 
• Logs data from meters periodically over RS485 using the Modbus protocol and stores it in the MySQL database.
• Records can be generated in pdf format with a selectable interval and date range.
• It also has WebUI for live viewing that shows a graph.
• My past was backend (python and SQL), built mostly from scratch.

Data Logger (M-Kris Electric) 

• Made using ESP-IDF and FreeRTOS
• It logs data from meters periodically over RS485 and then sends the data over the internet using Wi-Fi and HTTPS API calls.
• Built from scratch and all by myself (showoff? yes :)).
• Instead of plain c, I used C++ with some modern features including STLs, Type Traits, Classes, Function overloading.
• Well defined software architecture follows modularity, naming convention, readability, comments, decoupled modules. 
• At some point in time, I also tried to implement CI/CD by developing platform independent modules and testing using some c testing framework(lest). But I didn't continue using it because it seemed more time-consuming and tedious.
  
  

Handwriter (Personal)↗

A python script to create realistic-looking handwritten text PDF from text files using custom fonts.  I made it for personal use so that I don't have to write college assignments by hand.

Smart Home (Personal)

Made a smart switchboard that can be controlled via Alexa and WebApp, made using Arduino core for esp8266. I used sinric(a service for easily making Alexa-supported projects), and thinger.io (an IoT platform). 

Sewage Monitoring System (Personal) ↗

This is a college project. This device is made to monitor inside sewage parameters, humidity, temperature, methane gas levels and pressure build up. In this project, I have to connect STM32 MCU to ESP8266 via UART to connect it to thingspeak.  STM32 interfaces them with the sensors and ESP8266 uploads them to the thingspeak server using REST APIs.

STM32 Device Libraries(Personal)↗

Collection of libraries for interfacing external devices, developed using STM32 HAL. I made drivers for DHT11 (Single Wire Protocol), MAX7219(Serial Interface), MCP4725 (I2C), PCF8574(I2C) 

Embedded Software and Hardware Architecture

University of Colorado, Boulder - Coursera
In this I learned how to use compiler and linker, low level code, platform independent code, memory, memory model endianness, pointers and memory manipulation and some programming basics like control flow, data structures. And to be honest, quizzes are really hard, specially the last quiz, so I copied the answer :( .

Introduction to Embedded Systems Software and Development Environments

University of Colorado, Boulder - Coursera

This was the beginner course, although I was not a beginner (I thought) i did it to patch my gray areas.
In this I learned about the basics of embedded systems, c programming basics, compilation with GNU and GCC, platform independent code, Memory Types, Segments and Management

Learn Plus - The Complete Python

Spotle.ai

As the name suggests and nothing else, it was basically the 'basics' and not exactly 'complete'. It teaches how to use a python only and not how the python works. But it was a good start and the quizzes were also good.

Masterclass In Data Structure And Algorithms with Python and C++ (2 Course)

Spotle.ai

To be honest, the masterclass was only in title and not in actual course. I learned some basic to intermediate data types like linked list, array, stack, queue and some algorithms like sorting (bubble, linear, etc), done some quizzes and created some programming assessments like infix calculator, postfix to infix. 

The C Language in Action

Kenny Kerr, PluralSight

It was the basic course. Instead learning how to use C, it tells us how the C language works, it was like a practical overview. Its syllabus is like other basic courses, but it's not it covers the not so known basic parts of simple looking things like structure, how it aligns in memory (alignment and padding).

Modern C++ Secure Coding Practices: Const Correctness

Nick Cano, PluralSight 

In simple words, these courses teach why const are really necessary in modern C++ programming, from class method const, comparison, to assignment. How now using, const can have a huge problem like hacking or ultra long debugging session.
