I am Venezuelan; I live in Zurich, and I work in construction. In 2026, I learned to build apps with Claude. AURADUEL turns aura battles into a measurable sport, with on-device AR, no humiliation, and your body in motion. This is the story of why it exists, and what it took to reach Shipaton.1. The GenesisI grew up in a remote village in the state of Zulia, Venezuela. There was not much around, but I dreamed of three things: creating wonderful things, helping large groups of people, and building a family.At 16, I moved to Maracaibo. I enrolled in Pure Mathematics at the Faculty of Sciences of the University of Zulia. At the same time, I studied Geology at a technical institute. Two degrees at once, with very little money. There was not enough for both. I left Mathematics and finished Geology as a Higher University Technician. My thesis was a manual for processing seismic reflection and refraction data.2. First lesson: merit does not always winThat year, a classmate and I graduated at the top of our class. That is why we were given the two internship slots at PDVSA, the state oil company. The permanent positions ended up with two relatives of the head of the department. Neither had a degree.It was a disappointment. I moved to Caracas to find any job I could. I sold sportswear. Then I joined Maiquetía International Airport as an immigration officer. The country was falling apart. In government jobs, I felt political pressure to agree with things that went against my values. I left.3. Reinventing myself, twiceI started photography courses. I completed a diploma in contemporary art photography at Node Center in Berlin. I exhibited at Photo Lima 2015, and later in Madrid, Paris, and Germany. I lived from that work for several years.In parallel, I began a physical transformation. I competed in bodybuilding, in the Men's Physique category. In 2019, I became national champion of Venezuela and, that same year, South American champion representing my country.Through every stage, I stayed a fan of technology, science, and gadgets. It was a hobby that never turned into a job.4. Starting from zero, againIn 2020, the pandemic closed the galleries I worked with. My art career collapsed. I started coaching people in training and began studying nutrition.In 2021, Venezuela was in total collapse, and I emigrated to Spain. I went through several jobs. I built bleiquel.com, and until recently I coached fitness clients all over the world. I became a Spanish citizen, and that let me look beyond one border. In 2025, I moved to Switzerland with my partner.In Zurich, I could not find work in my field. I do not speak German, and my English is intermediate. I took a job in construction. I am still there.5. 2026: I discovered I could build softwareIn early 2026, I discovered Claude and what could be done with it. I saw the chance to build big things on my own. I entered this world alone, at night and on weekends, after my shift on site.The first thing was something I knew well: NEXVYVE, an app that helps people live healthier with diets, workouts, and supplements personalized to their goal, at a low price. It was what I did as a coach, for many more people.6. Why AURADUELThen I saw "aura farming" explode on social media: teenagers challenging each other to see who has more presence. I researched where it came from. I found two things.First: the trend is born from bullying and from the fear of self-expression in children and teenagers. Second: it is a social activity. It creates new friends and healthy environments. It is about the vibe, about showing who you are.That is personal for me. I am gay and I come from a country where that "was wrong". I worked very hard on myself to accept who I am and to stop letting other people's opinions hurt me. I know what it costs to show who you are in front of people.So I decided to build AURADUEL: a platform to play, a fun system that adds magic and spark to people in an augmented reality game. With one rule that is not negotiable: nobody loses in a humiliating way. Aura loss is aggregated, capped, and recoverable.7. A game you win by movingThere is one more thing I discovered while building it. An aura battle is not played with your thumb. It is played with your body: posture, arms, changes of rhythm, holding someone's gaze. The phone only watches and scores.That matters. The World Health Organization recommends that children and teenagers get at least 60 minutes a day of moderate-to-vigorous physical activity. Its 2020 guidelines sum up the benefits: better cardiorespiratory and muscular fitness, stronger bones, cardiometabolic health, better cognitive and academic performance, and fewer symptoms of depression.I lived that part myself, over years of training: changing my body changed my mind long before it gave me a title. A game cannot promise that, and this one does not. What it can do is reward what moves. The Aura Score scores sustained presence, creativity in the gestures, energy. Standing still scores low. Every round is a few seconds of intense movement in front of friends, in a plaza, in a school hallway. It does not replace sport. But it turns screen time into body time, and that is already a win.8. What I builtThe repository was born on August 20, 2026. As of September 3 it has 309 commits and 864 unit tests passing.All biometrics (gesture and pose with MediaPipe) run on the phone. No body landmark ever leaves the device.The AR effects (spheres, sparks, verdict) are drawn in real time with pixi.js on top of the camera.It is a PWA (React + Vite + TypeScript) wrapped with Capacitor for iOS. In-app purchases (cosmetics first) run through RevenueCat.Game rules that come from the research: paying never improves the result, no loot boxes and no vote buying, on-screen image consent before every battle, no open chat and no livestream.9. What Shipaton forced me to do (and what went wrong)Shipaton requires publishing to a store inside the window. That forced me to do the iOS wrap, the App Store listing, the privacy policy and terms, and the RevenueCat integration, all within weeks.Apple rejected version 1.0 the first time: guideline 3.1.2, a missing functional link to the Terms of Use in the listing. It was metadata, not the binary. I fixed it from the web console and resubmitted on September 2. As I write this, the app is waiting for review.10. What I learnedMerit does not always win, but effort compounds. Every job I had is inside this app: the photographer's eye in the effects, the athlete's discipline in the 309 commits, the geologist's head in the scoring.You can start from zero once more, in a new country, in a language you do not speak, after a full day on a construction site.A game for teenagers must be designed first to protect them. Then to be fun.If you are building your Shipaton app from a similar place, with no team, no investment, and hours stolen from sleep: it can be done. I am doing it.
