About

Hey everyone, welcome to my blog! I’m Romario López (@rlopzc), a seasoned software engineer working primarily for startups. Thank you for taking the time to read what I have to share, I’m sure you’ll find something useful!

Most of what I’ve learned has come from blogs. I want to give back to the community that has helped me a ton. I’m mostly going to write about software engineering topics: programming languages, system design, cool stuff I’ve built, tips, infra, etc. I love programming; I’ve been doing it for the last 10 years. It’s a joy to go from an idea to a real project/product with your bare hands and a computer.

I’ve been working as a software engineer professionally for almost a decade. My journey spans roles at Wizeline (acq), Arcus (YC S13, acq by MasterCard), Nubank (IPO), Co-Founded my startup and got into YCombinator (Okani YC S21), traveled the world with GitStart (YC S19), and currently working at CoreCare (YC S20). I’ve had the opportunity to work on a variety of projects, from optimizing infrastructure and enhancing team efficiency to co-founding a startup, navigating international expansions, pioneering streamlined processes, and building open-source projects. As you can see, I’m heavily into YC startups and I even got into YC myself 😬.

Through these experiences, I’ve worked in the whole stack:

I’ve been working with Elixir for the past 6 years. I’m going to publish what I found useful and information that I think is not out there already written. I’m looking forward to sharing what I’ve built with Elixir’s OTP (processes, supervisors, agents), for example: concurrent non-blocking serial queues at scale.

If you find something useful, leave a reaction or comment! This motivates me to continue writing. If you think I’m wrong, also leave a comment and we can discuss it! It’s in ourselves to make this community live. Contact me at [email protected] or @rlopzc on X (Twitter) if you have any feedback. Looking forward to hearing from you!!

As a side note, I’m into games. I’m currently playing Green Hell (hard af), LoL, and Diablo 4. I initially wanted to get into software as a game developer ha. I’m also into fixing stuff by myself (in the real world 😜), I want to learn how to fix electronic stuff, furniture (currently my PS5 is broken), etc.

I’m also open to writing about something you find useful or you think I know about! For example: startups, development processes, raising money, etc. You can leave a comment or send me an email, I’m happy to hear your thoughts!
