After quiting my first job(magento & wordpres) I did not wanted to bind myself within any framework. I always prefer raw coding more than any heavy framework. I know how frameworks are made, how they work, how any MVC serves. I can built my own MVC. Allhumdulillah, I have succeded to built a complete, big and fully production level ERP without any help of a heavy framework.

Server Configueation & Maintainance

I have experience of web server configuration. RetaDesk(running on production) is hosted on a dedicated Ubuntu Server and the server computer is fully configured by me.

Despise that I also have knowledge of DNS, FTP, SMTP server configuration knowledge and experience on Red Hat Linux(Learnt at my BSc)

Operating Systems I am familiar with:

  • MacOS
  • Windows
  • Ubuntu
  • Red Hat Linux
  • Ubuntu Server

UI, Graphics and Media

I was always interested to graphics design. Photoshop & Illustrator are always my favourite. I had to do all my graphics design by my sellf after I quit Valobazar. Even before that I have done so many graphics works for my university. The knowledge of graphics design helped me a lot for UI design. I can maintain the UI standard of all the interfaces and layouts of softwares I develop.

I hope you may feel it while exploring all my projects.

I also have experience of video editing as I had to prepare videos of/for some programs arranged by organizations at my university while I was in first year.

Me as a Full-Stack Software Engineer

As a full stack sofware engineer I have to do all the things from concept design, layout design, database design, backend and frontend coding to quality testing. As a full-stack developer I have performed best while developing RetaDesk. I had to collect all the nacessary information and data, design the conpect of the software and then design the various layouts of the software. After the layouts of a particular system is ready, then I started coding.

I have a very strong knowledge and experties on Database. RetaDesk currently has more than 80 tables for storing various data of a retail business. The whole database is made by me from sketch. I use both raw SQL and ORM for working with database. I can work easily with complex queries for fetching data from different tables, no matter how many tables there are and how complex the relations are. I think this is the best part of my knowledge on database. RetaDesk is full of complex queries which made the system extremely fast by removing a huge pressure from the web server. You know, no ORM can perform better than raw complex queries while working with relational data from multiple large tables based on multiple conditions and relation.

I have a good experience as a trainer. I have taken several courses, workshops and seminars on my university and at my office.

I have also taken some workshops and seminars on web development and career on web sector at my university.

I have some other small projects which I have not mentioned in "My Works". Here is a list of small projects that I have done in my career:

  • 1. Matrimony/Matchmaking website: This was a social networking project and the very first project of my career. This is the project by which I started learning and working with PHP and MySQL.
  • 2. JAVA Based Inventory Management System: This was my first and only JAVA project which I have done for my academic course. The project had the fundamental needs for managing the inventory and sales by a small shop. I had scored the best on that course for that project.
  • 3. PHP Based Business Management System in Bangla: This was my first business or inventory management system which I developed for one of my relative and still now he is using this software for managing the informations of his business. The software was in Bangla so that any people could easily use it without any good knowledge of using computerized system. The project was based on raw PHP, MySQL, JavaScript and Jquery.
