Tommy and a Dog

👋🏼 Welcome to my spot on the web!
My name is Tomás Peñaloza Avilés and I am a 🇧🇴 Bolivian developer and engineer.

Since I was a child, I've been very active, curious and keen to try experiments. So I ended up with a degree in 🧑🏻‍🔬 Chemical Engineering and it gave me a superpower: a scientific approach to experiment and understand the way things happen.

During my degree, I realized I also liked coding and had some talent at it. So I decided to explore a whole new field, the 💻️Software & Web development universe. And I loved it! Code allows me to build highly scalable tools with potential to transform and improve the daily lives of people, companies and institutions. It's another ⚡️ superpower! But you know... "With great power 🕸️ comes great responsibility".

So now, I'm looking to use these superpowers to make a difference in the world. My purpose is to make things that matter, things that generate value to humanity, to life and to this astonishing world. I believe that with a good idea and a highly committed group of individuals that colaborate together, there is nothing that can't be changed for good.

Favourite Quotes


Truth ―more precisely, an accurate understanding of reality― is the essential foundation for producing good outcomes.

Ray Dalio

A calm mind, a fit-body and a house full of love. These things can be bought, they must be earned.

Naval Ravikant


La vida está injustamente corelacionada con la gente que uno conoce. Si uno nace pobre y se rodea de gente pobre, uno va a ser pobre. Si uno nace rico y se rodea de gente rica, muy probablemente uno va a ser rico. La buena noticia es que apenas uno lo entiende, uno puede hackear el sistema.

Freddy Vega

Somos antorchas, solo tenemos sentido cuando nos quemamos; solamente entonces seremos luz.

Luis Espinal


Puedes enajenar tu vida, dejar que te la compre el mercado, pasarte la vida pagando tarjetas y comprando cacharros. Le das pa' delante y al final estás como un viejo como yo lleno de reumatismos... ¿Que hiciste en este mundo? Pero si tuviste un sueño y peleaste por una esperanza que la transmitiste a los que quedan, tal vez quede un pequeño aliento rodando con el viento, en las colinas, en los mares. Un pálido recuerdo que vale más que un monumento.

José Mujica

Hable más fuerte, que traigo una toalla.

Homero Simpson


Random facts

  • When I was a child, I went camping with my scouts group. We couldn't set a good fire and we ended up eating half cooked rice. Also, my friend set up the tent over a big cow's poop. We only realized that at the end. At night we slept very comfortable and thinking that nature smells very funny.
  • Can do a very tasty 'Chili con carne'. Not too spicy but with a lot of flavor and fries!
  • I have a fascination for the adrenaline you feel on roller coasters.
  • Just recently, I discovered a taste for poetry. One of my favorite poems it's called   "Itaca" by Konstantino Kavafis .

  • Even though I almost drowned when I was 4 years old, once I was able to jump into the pool by myself I've loved swimming for the rest of my days. I even made competitive swimming for some years as a teenager.
  • Choosing between movies or series, I would prefer watching movies.
  • I'm a fierce practitioner of daily exercise, eating healthy, fasting and meditating.
  • Been learning about Bitcoin, blockchain and crypto since 2020. It's a revolutionary field. But I really think everyone should learn about personal finances before entering to this world.
  • Cats are nice, but I'm definitely a dog person 🐕️❤️.
