Hi! I'm Manuel Doncel Martos (a.k.a. manuelarte).
I’m a Technical Lead with experience building large-scale, user-facing systems and distributed architectures. Most of my work is in Java and Go, but I’m always learning (currently exploring Python and Rust). I enjoy solving tough engineering problems, experimenting with new technologies, and continuously improving how software is built and operated.
Feel free to reach out or connect with me through the following platforms:
I'm always looking to learn, grow, and contribute to exciting projects. Currently, I am learning UI/UX, working on a web app to record and keep track of the goals/assist in your football games, FlexingMyGoals.
I also like to read technical books, the last one(s) I read or am reading are:
This is my GoodReads profile.
From time to time, I write short posts about engineering topics that often show up in day‑to‑day work but are not always well understood:
I care deeply about code quality and about reducing cognitive load for developers. One way I approach this is by building custom Go linters that encode and enforce a team’s agreed‑upon guidelines, so developers don’t have to remember or debate them during code reviews. Instead of relying only on conventions or review comments, I prefer making expectations explicit, automated, and consistent. This allows teams to focus their mental energy on solving real problems rather than on formatting or structural debates.
- funcorder: Check that exported functions are declared before unexported ones.
- embeddedstructfieldcheck: Check that embedded structs are declared first and with an empty space between the embedded and the non-embedded struct(s).
- godddlint: Check some good practices when creating domain objects (Entities and Value Objects).
- testcomments: Check test practices described in TestComments.

An Android app designed for amateur and recreational football players to log their matches, track individual goals, assist and evaluate their overall performance. The app provided statistics and insight such as total goals, assists, progress over time, etc., helping players improve their game and stay motivated.
A fun and interactive Discord bot designed for Escape From Tarkov players to log and track team kills among friends. Whenever a team kill is registered, the bot delivers a humorous roast to the team killed perpetrator. It also had achievements to "reward" 🏆 players for their "friendly fire".
A web app to keep track of your football boots, and your performance, goals and assists using them. It featured an Event Sourcing and CQRS with the Axon Framework architecture.
During my career as a software developer, I have had the privilege of working alongside many talented professionals. Here I give kudos to some of them:
