Right, no longer with an X account.

Transcription from Valencian: “El C1 és teu”, which means the C1 is yours, written in Valencian or Catalonian. Lovely support drawing done by my partner.

Am I crying? I finally got my C1 Valencian certificate by CIEACOVA, I just read the final results after my first two exams from my masters in teaching. Wow, I can’t believe it, I got 7 out of 10 (6 was the minimum to gather this certification). Yes, I am crying 😭

Manifest Android Interview by Jaewoong

Today, it’s time to thank @github_skydoves for writing this comprehensive guide book. This do not only remembers the key concepts you need to master on the complex Android ecosystem but the good practices, I am loving it (yes, I just got my latest update).

Mobile system design interview book by Manuel Vivo on top of System design interview 1 and 2 books by ByteByteGo

Who could tell I am a fan of system design? I completed my collection thanks to @manuelvicnt and his excellent “Mobile System Design interview”. When I used to be one of the main interviewers of system designs, this would have recall me accurate good practices #mobilesystemdesign

Here we go again, let’s refresh those Android little things. Thanks for this comprehensive summary @github_skydoves ! I got my digital Manifest Android Interview copy for my classic kindle 🤓

I am a bit rusty preparing interviews indeed, now that I am learning how to teach in my masters, I do find the most valuable asset someone may have is time management. These days I start studying a subject from a module and I end the day reviewing some kotlin or android stuff.

Hoy es mi día de suerte, ya puedo ver a Steven Wilson en Madrid con una camiseta molona 😎

Kotlin in Action book by Jemerov and Isakova, first edition

This very old friend has been handy to my assignments on my teaching master’s. I am enjoying teaching kotlin with my didactic materials. Not only in conferences for now. Would you be interested in this journey at any conference at all? I even created a mock podcast #teaching

That or I am expressing my profile and myself wrongly. I am not sure, food for thought I suppose. Have a good week, friends. #whenyoudonotlookforjobnow #recruitersinvestigation #jobhunting

I mean, if you contacted me, you know I am remote, as well as the companies I worked with were at scale of millions, solving complex problems in terms of usability and performance… that might give you a clue about something broken in the investigation you have done. (continues)

More often than I used to I am puzzled with some feedback I received just from a primary conversation with recruiters. Things like you’re overqualified for this role, we are looking for profiles with more exposure on applications at scale, we hire in London only… (continues)

I know, I had to go earlier yesterday. If you come by Spain let me know.

Congrats as usual to JB for organising such a complete event, and all new friends I met during this time #kotlinconf This will be my last one for a bit (lay offs have striken me this time). if you want to reach me for a staff role, I am open to listen www.linkedin.com/in/raulherna...

Today is last day at #KotlinConf. My purpose is to normally meet at least two new friends during the conference, I am happy that one more year I not only met two but probably four, networking is the best at this amazing conference.

Hello 👋🏼 #KotlinConf!

This is me this evening… I am so ready #KotlinConf 🤓

What is best than travelling to Copenhagen to attend #KotlinConf? Doing it at the same airplane one of my besties does 🤘

Who am I seeing this week on KotlinConf in Copenhagen? Probably my last one for a while, if you see me, come by and say hi! #KotlinConf25

Happy holy day of heavy metal to all of you 🤘
Ronnie, my good friend Ronnie James Dio RIP. Today I’ll listen to Holy Diver for you.

What a seasoned android engineer does these days to prepare for a job interview? I haven’t prepared for this in years. Happy to learn from you ✍️ thanks in advance! #maytheforcebewithyou

There is something definitely happening. DeepSeek has shaken all AI related things, not only the Nasdaq. I believe this is telling us to be open to all interesting discoveries over the world, rather than only focus on a specific thingy. #AI

When I was 15 I took my high school English exam. The essay question was to argue whether the internet would be good or bad for humanity.

At that wee age, a long time ago, I wrote that the internet would inevitably be ruled by the ‘fat cats’ of society and corrupted to control people.

Huh…

Let’s see what this 11111101001 year brings

2025 is 0% complete. Happy new year

I’m the kind of person who adds their slack state when on vacations but definitely forgets to add the same at the calendar as OOO. Luckily I did after all 🤣. Merry Christmas 🎄 and a Happy New Year!

DooM is 35 years old. Time flies.

My favourite sentence now is “I am open but not happy to”
