About the Author

Hi, I'm Wilberto Pacheco Batista. Senior Full Stack Engineer, full-time dad, and the person who has to explain to his family why there's a Raspberry Pi plugged into the living room router "for work reasons."

I live in Broken Arrow, Oklahoma, with my wife, my daughter (currently operating in full toddler chaos mode), and my two dogs: Papi and Santa — who have very strong opinions about when I should close the laptop and take them for a walk.

Spoiler: their opinion is always right now.

The Origin Story

I grew up in Havana, Cuba, where I studied Computer Engineering at the Universidad de las Ciencias Informáticas (UCI), graduating in 2010. I left with a degree, a lot of ambition, and absolutely no idea how cold Oklahoma winters would eventually feel.

That was over 14 years ago. The ambition is still there. The hair, slightly less so.

What I Do Professionally

I'm a Senior Full Stack Engineer with a strong frontend focus — React, Next.js, Vue.js, Node.js, TypeScript. Over the course of my career I've worked at ICIMAF (Institute of Cybernetics, Mathematics and Physics) in Cuba, and at Velocigo Inc and TPV.com in Oklahoma, and currently at Included Health, a digital health company in Silicon Valley.

For well over a decade I've been making calls that actually ship: architecture, code reviews, migrations, feature flags, performance. What I most want to write about is often what I'd do differently with hindsight — that's usually where the lesson is.

Why renderlog.dev Exists

One day I went looking for quality frontend content in Spanish that wasn't a rough auto-translation or a "hello world" tutorial. I didn't find much.

So I built it myself. Because that's what engineers do when something doesn't exist.

Here I write about what I actually use at work. Not textbook theory — judgment built over a decade of mistakes, refactors, and production deploys that sometimes went well and sometimes didn't.

Everything is published in both English and Spanish, because both communities deserve quality technical content and I happen to speak both.

Side Projects

When I'm not working, I code for fun. Some projects come from an idea I can't shake at 11pm. Others I build for my daughter, who is two years old and has an uncanny ability to find every edge case in any UI she touches — the best QA engineer I've ever worked with, honestly.

• micalpacheco.com — a landing page for my wife; the only goal was that she'd love how it turned out. She did.
• paint.wilbertopachecob.dev — a drawing app that lives in the browser. Started as a canvas API experiment; ended up her favorite activity for all of five minutes.
• tictactoe.wilbertopachecob.dev — classic tic-tac-toe. Clean, simple, works on any device. She doesn't understand the rules yet but loves tapping the screen, which honestly describes a lot of users.
• weather-ai.wilbertopachecob.dev — a weather app with AI baked in. Born from pure curiosity. Also: Oklahoma weather is genuinely unpredictable and I needed answers.

All of this runs on a Raspberry Pi 5 at home, exposed to the internet through Cloudflare Tunnel. Yes, including this blog. It's my favorite way to learn about infrastructure without paying for it.

Outside the Keyboard

When I finally close the laptop — usually because Papi is barking at it — I like to:

• Hiking and the outdoors — Oklahoma has surprisingly good trails, and walking the dogs is the most effective way I've found to stop thinking about code. Papi sets the pace. Santa sets the drama.
• Traveling — I have a running list of places I want to visit that grows faster than I can check them off. My daughter is already adding her own suggestions, though for now they're all some variation of "grandma's house."
• Family time — my favorite version of disconnecting is actually connecting with the people who matter. Wife, daughter, Papi, Santa — the whole crew.
• Chamomile tea — yes, seriously. A senior engineer drinking chamomile tea while reviewing PRs at 10pm is a completely valid lifestyle and I will not be taking questions.

A Word About Papi and Santa

Papi and Santa are the unacknowledged co-founders of renderlog.dev. Their contributions include sitting directly on the keyboard at critical moments, barking during important calls, and reminding me that the best debugging technique is sometimes stepping away from the screen and going outside.

They are never wrong about this.
