Welcome to my homepage
I'm amused by the Internet, computers, blogging, traveling and socializing with quality people. For me, it has been always about learning something new and solving engineering puzzles!
I am a Software Engineer (Level 03) working at Treebo Hotels. My job here is to work with an aggressive and an innovative team to design & develop the central reservation system that runs on Python and built on Flask. Here, I also maintain the prime hotel front application back-end which is used by FDMs to manage and run their operations.
I spend my leisure time (which I rarely get), learning and taking up courses on MIT OCW, through which I try to understand the practicalities of Computer Science. I take some time out every now and again, to read books (autobiographies) & articles and also to write (seldom).
Views & Philosophy
I believe that, the Terminal will always remain the coolest user interface regardless of advancement of attractive GUIs. I try accomplishing most of my quests via terminal, and someday I will ditch my desktop environment and switch to window permanently (retirement plan).
I'm a GNU/Linux lover and I support & contribute to free and open source software (FOSS) community.
I prefer Vim over Emacs!
And yes, if you are wondering about the word 'hackr' (hacker) in my handle/username, then I wish to add this:
A hacker to me is someone who enjoys playful cleverness not necessarily with computers.
- GNU Philosophy.
Areas of Interest
I would like to educate myself about Algorithms, Computer Networks, Linux Kernel Development, and Cryptography & Security.
Other than computers, I love food, like to travel to exotic places and, occasionally, I do find some time for recreational activities.
Projects & Achievements
I started my professional work experience as a Full Stack Developer at Omnify Inc and walked out as a Senior Engineer after working for a year (February 2017 to March 2018). My responsibilities here were to develop, deliver and scale the core system that runs on LAMP stack. During my tenure, I'd also focused on Developer Operations to find and implement effective methods for horizontally scaling of an application.
I'd also designed and developed APIs, libraries & modules for Kohana framework.
Wrote a command-line tool for using tumblr in terminal, teblr, which supports basic operations such as posting, editings and deleting posts.
I've previously worked on usersys, this was my first project (somewhat as a git repo), which was a configurable user system for Laravel.
I have been an information security advisor for various media channels during my graduation. And so, I have been published and interviewed by Telegraph and television networks like Zee on the topic of ethical hacking and network security.
Also during my graduation, I'd discovered and reported Cross Site Scripting (XSS), SQL injection and Remote Code Execution bugs on college Intranet servers.
During my college time, I had conducted several workshops at different institutes on the topic web development, web security, and ethical hacking to over 600 students.
