IIMore About Me

Building purposeful solutions

I'm Marcus Gomes, a software engineer with more than 15 years of experience, currently a Senior Software Engineer at Apollo.io. I'm passionate about solving complex problems and building solutions that actually matter.

Key Areas I Work In

Frontend

React · Next.js · Three.js

Backend

NestJS · Rust · Node.js

DevOps

AWS · Kubernetes · CI/CD

Blockchain

Solidity · DeFi · Web3 auth

My main stack includes TypeScript (NestJS, React, Next.js), Rust, Solidity and AWS/Kubernetes, but more than just knowing tools, I care about using technology in a smart, clean, and efficient way.

What drives me is turning ideas into reality. I've been a CTO, a co-founder and a founding engineer, taking products from zero to production and leading teams that consistently deliver high-quality work.

Outside my day job I build my own products, like Lotvs, Breakwatch, Servyx and Yield Sniper, and I write: my first two books are out now on Amazon.

At the end of the day, my work is about clarity: removing the noise and making things actually work.

VWriting

Books

My first two books are out now on Amazon. One brings Stoic philosophy to the daily life of people who build software; the other is a personal book of meditations.

A Daily Thought of a StoicDev

Ancient Stoic wisdom for the people who build software

by Marcus Gomes · Kindle & paperback

One page for every day of the year. Each page pairs a passage from Marcus Aurelius, Epictetus or Seneca with a short reflection for people who build software: in the code review, during the outage, before the hard conversation with your team.

by Marcus Bego · Kindle & paperback

Eighty meditations in eight books, on the inner frontier, work, money and freedom, love and fatherhood, and the unfinished man. Written while still climbing, not from the top of the mountain.
