Lucas Albuquerque
Founder & CTO. I grew 33,449 followers from a blank profile with zero ads, writing about fundamentals, careers, and the moves that scare you a little. Everything I know is public.
Live from LinkedIn
Real posts, real numbers. Nothing here was boosted, bought, or written by a committee.
At 27 I got an offer to work in Abu Dhabi. Everyone said it was crazy. Stable career, wife, friends, family. Why risk it? I went anyway.
Most senior engineers I have interviewed would fail a simple fundamentals test. Not because they are weak. Because the industry rewarded framework fluency over depth.
The API handles 10,000 req/s. The database handles 10,000 queries/s. At 200 concurrent requests, everything locks. The bottleneck was connections, not CPU.
At 12, with no money and no coding skills, I built one of the most visited sites in Brazil. Blogspot banned me. I had to learn PHP, MySQL, SEO, and keep going.
Cache invalidation is one of the two hard problems in computer science. Most engineers solve it with a 5-minute TTL and a prayer. Here are 5 patterns I actually use.
The skill that changed my career is not Kubernetes, not a database, not cloud. It is storytelling. It closed the Abu Dhabi invite and raised money for a startup I cofounded.
Stability is the biggest risk to your career. And nobody warns you. When you get comfortable, you stop learning. When you stop learning, the market moves past you.
Who I am
I started at 12 on a patched computer with a bucket catching rain from the roof. That site became one of the most visited in Brazil, got me banned from Blogspot, and taught me PHP, MySQL, and SEO out of pure necessity.
Since then: engineer in Brazil, then in dollars, then 31 countries as a nomad who still shipped. An AI product in Abu Dhabi. Founder and CTO. Somewhere in there I started writing in public, and it opened doors a CV never did.
Hire me
Mentorship if you want the job. A talk if you have a room. Ghostwriting if the work is done and the words are not. Same person. Pick the door that fits.
01
Three sessions for engineers who can do the work and still lose the process. Study plan, LinkedIn that gets you noticed, jobs that never hit Easy Apply.
02
Keynotes and company rooms. LinkedIn that compounds, how to actually ship an MVP, and how to work as an AI-first professional. An operator on stage, not a motivational deck.
03
For founders and executives who already have the work and no calendar left to make it public. I write in your voice, LinkedIn only, and you approve everything.
From the blog
Engineering
Most senior engineers I interview would fail a fundamentals test. Frameworks change. Networks, databases, memory, and concurrency do not.
ReadCareer
Stable job, family, friends. I went anyway. The first three months were the worst. They were also the ones that rebuilt how I work.

Comfort looks like safety until the market moves. If your work has not scared you in two years, you may not be growing.

Cache invalidation is still one of the two hard problems. Five patterns I actually use, and the traps I refuse.

10,000 req/s on paper. 200 concurrent requests and everything locked. The leak was connections.

New writing ships there first, every week. This site is the cut worth keeping.
Open LinkedInThe path
Built one of the most visited sites in Brazil on a patched PC, with a bucket beside me catching rain and an unpainted block wall in front of me. Blogspot banned it. PHP, MySQL, and SEO were the way out. It paid for college.
Writing software for Brazilian companies before I could legally drink. Then a hundred interviews until the offers came in dollars. Europe, the UK, 31 countries as a nomad who still shipped.
An early AI product into production, in a room of accents and cultures where nothing could be implicit. Competence was the floor. Communication was the job. Everyone said the move was crazy.
Building the company by day. Publishing in public. Mentoring engineers, giving talks, and writing for a few people whose work is ahead of their name.
Right now
The company. Founder and CTO, shipping product with a small team that moves fast.
Mentorship, talks, ghostwriting. Three doors. Book a call and we pick the one that fits.
Weekly on LinkedIn. Fundamentals, careers, and the parts of the market nobody says out loud.
Coffee with the Dev. Answering the questions you send me, with a coffee, no script.
“You can be the best in the room and nobody notices. Writing is what changes that.”Follow on LinkedIn
Questions
Mentorship. Three sessions: a study plan, LinkedIn that gets you noticed, and a hunt that does not live inside Easy Apply. Book a call and we see if we should even begin.
Yes. Three talks: LinkedIn, shipping an MVP, and working as an AI-first professional. Details on the talks page. Book a call with the date and the room.
For a few founders and executives whose work is already ahead of their reputation. That is ghostwriting. LinkedIn only. You approve everything.
Not right now. I am Founder and CTO and focused there. If you want help getting hired, that is mentorship.
Yes. Readers in Brazil land on the Portuguese version automatically, and the switch in the header changes it any time. Posts start in English on LinkedIn, Coffee with the Dev is in Portuguese, and talks and mentorship happen in the language of the room.
Mentorship, a talk, or ghostwriting. Thirty minutes. I will tell you honestly which one fits, or if none of them do.
