iOS Developer at Pentalog, TCS, Brounie, Knotion, Digono, Pixan and LJN (2014-06 – 2019-10)

Five years building and maintaining native iOS applications across fintech, healthcare, education, ride-hailing, museums and consumer products. Shipped and supported apps in the App Store using both Swift and Objective-C, working in teams of 3 to 8 engineers and frequently owning features end-to-end alongside Product, Design and QA.

Highlights include: building a specialized iPad app for Oncology specialist meetings (Pentalog); developing consumer apps such as Loundry and UpNGo and integrating Parse + JavaScript Cloud Functions as a backend layer (Brounie); contributing to a large EdTech application with a real-time WebSocket layer and migrating modules toward VIPER architecture (Knotion); building museum apps, content apps for Larousse and a geolocation-based event app, Enloop (Digono); and shipping Priver, an Uber-style ride-hailing app, plus ongoing maintenance of an existing App Store portfolio (Pixan). During this stage I consolidated my expertise in UIKit, Auto Layout, Core Data, networking, push notifications, third-party SDK integrations and the App Store release process; adopted modern architectures (MVVM, VIPER); and started taking on technical interviewer and trainer responsibilities for new iOS hires at TCS and Digono. Front-end work at LJN (HTML/CSS/JS for a CDMX taxi-booking product) complements the iOS background with a basic understanding of web stacks.
