I've been a software engineer for 20 years and I'm currently CTO at Plubi. I like taking an idea all the way to production. I design the architecture, write the code, run the infrastructure and ship it, on the web and on mobile.
I started in 2006 integrating systems for the printing industry with Perl, TCL, Ruby, Bash and AppleScript. Over the following years I built web applications, iOS and Android apps, Linux servers and high-availability clusters.
In 2020 I studied the financial markets and built trading bots with MQL, Python and Profit Chart's scripting language. In 2021 I moved into Web3, building dApps with React, Next.js and TypeScript and smart contracts in Solidity.
From 2022 to 2024 I was a tech lead and full stack engineer at Hero99, working on inventory, payments and sports tournament products with Next.js, NestJS, Python and Kotlin. In 2024, at Yssy, I worked with Next.js and NestJS and built CI/CD pipelines on Azure DevOps and Jenkins.
At Plubi I'm responsible for architecture, development and cloud infrastructure, with Angular, Spring Boot, Python and Ruby on Rails. Outside work, I build and publish my own apps, such as FlowDrama.
A rehearsal platform for actors on the web, Android and iOS, in 10 languages. My own product, from the idea to the infrastructure.
Plays: import a script, assign the characters and generate AI audio for every line. Then hide your lines and rehearse from memory, even offline.
