If you need to contact me faster than sending an e-mail (I only read it once a day before sleep unless I am expecting a mail), then below are the ways to contact me.
Based on my preference I have marked them as green or orange where green is the most preferred way, and orange is a less priority for one or more reasons.
If you think that my preferences are inconvenient or extreme, please read why go through this hassle, and this is extreme sections.
If you are still not convinced to use free software for contacting me, please stick to sending e-mails.
e-mail: firstname.lastname@example.orgIf you received any another mail address with the same codingotaku.com domain from one of your contacts, please use that one to send the mail.
If you want an official talk, please do send the mail from your (or company's) domain to not lose credibility.
Instant MessagingIM must only be chosen when the communication is unofficial, all official communications must be done through mail for better record keeping for all of us.
XMPP (Originally Jabber): email@example.comIf you have an account on any server that is compatible with XMPP Protocol, please use that. Just like an e-mail, having a decentralized way of communication makes sure that neither of us need to install any specific software or go through the hassle of creating and deleting an account.
Matrix: @codingotaku:matrix.orgAnother decentralized way to contact me, I use the element client for matrix, it has support for E2E encryption, and also supports video conferencing through Jitsi.
SignalTo communicate through Signal, we both need to share our mobile number.
I do not trust most people with my number as they might have installed programs that pulls, stores, and use numbers without the permission of all the unfortunate people in the contact list (e.g.: WhatsApp, true caller, Gmail, LinkedIn, etc.).
For the same reason I also avoid installing those kinds of software. But I can trust Signal to the most degree as the number is only uploaded after hashing it from the client side. And is fully free software
If you prefer this mode of communication, please let me know in mail.

Jitsi MeetOne do not require an account for this, any server that hosts a Jitsi server will be sufficient. If you don't have one, go to https://meet.jit.si/ to start a secure video call.
BigBlueButtonThe best conferencing service ever! But I do not host one(yet). If you have a server and would like to get rid of privacy invading conference services, please use BigBlueButton. It is not hard to do it, I would love to help you set up one for gratis if the use of BBB is guaranteed in the long term.
Jami: 674286597de4e38c2a72d23dfb3a5783966794a3Though I really like the Idea, Jami is unreliable most of the time for me. Since the program is peer-to-peer, both parties are required to be online to start a conversation.
It also doesn't have support for group video calls.
MumbleMumble is a free software just like all other programs I use.
One do not require an account or server either to use mumble. But hosting a server is preferred to avoid using public channels.
Phone callFor the same reason as Signal, I tend to avoid sharing my number. I have fewer issues to share it with the employer if the job is guaranteed. But please use it only for record keeping and for emergencies.
If for some reason I shared my number with you, do notify me before you call through one of the mediums mentioned above, I do not save numbers unnecessarily and usually avoid calls from unknown numbers for my sanity.
