ABOUT ME

Lead Mobile developer @ jpg.store. Previously iOS at  & many more!

As a Staff Backend & Lead Mobile Engineer, I've navigated through diverse sectors such as fintech, retail, online collaboration, machine learning, education, and consulting, contributing to leading companies including JPG Store, Apple, Brubank, Mural, Austrian Institute of Technology, Mimo, Theorem, and Wolox.

Aside from leading technical teams, I find fulfillment in mentoring others. I'm an active mentor at CodeMentor and MentorCruise, with more than 60 ⭐⭐⭐⭐⭐ reviews. This role has allowed me to guide many developers on their career paths, share insights from my professional experience, and teach advanced programming topics that you learn only when you have had several years on the industry.

I have a strong educational background, with a degree in software engineering from ITBA (Argentina, 2017) and a master's degree in software engineering from UAS Technikum Wien (Austria, 2018). I'm also expanding my horizons into philosophy at USAL since 2021.

I have a proven track record in:

- Conducting code reviews

- Assessing candidates through technical interviews.

- Leading and proposing architectural decisions.

- Working with complex problems, such as sockets in online collaboration.

- Delivering workshops and talks on Combine, Rx, App Architecture, Coordinators, and Unit Testing.

- Configuring and building automation workflows for different apps using Bitrise, Jenkins and Fastlane.

- Advanced react native knowledge.

My technical expertise spans:

- Over 5 years of experience with Node.js, Nest, PostgreSQL.

- Over 8 years of experience with React Native (and React JS)

- Over 10 years of experience with Swift, SwiftUI, and Objective-C, including mastery of Rx technologies (RxSwift and Combine) and multiple design patterns (Coordinators, MVC, MVVM, Unit testing, crash reporting, CI, automation, storyboards and programmatic views).

- Over 2 years of experience in Python and Machine Learning (AI), where I worked and helped advance the state of the art in synthetic dataset generation for object detection.

- Tools like Firebase, Firestore, Splunk, and automation (fastlane - github actions).

Some of my professional achievements include an honorable mention for my Master Thesis, winning a hackathon organized by Wolox, and contributing to high-rated (4.9+) apps on the App Store.

I'm always open to discussing software or philosophical topics. I sporadically write to my blog, you're welcome there https://deep-thought.netlify.app/pages/showcase

Looking forward to connecting,

As a lead mobile developer in react native, my primary responsibility is to design and develop high-quality, scalable, and user-friendly mobile applications for iOS and Android platforms using the react native framework. I work closely with the product manager and cross-functional teams to understand the requirements and translate them into functional and visually appealing mobile applications. I am also responsible for leading a team of mobile developers and ensuring that the project is delivered on time and within budget. I provide technical guidance and support to my team members and review their code to ensure that it meets the required standards. In addition to my technical skills, I have excellent communication and leadership skills and can effectively coordinate with various stakeholders to ensure the smooth functioning of the project. I am constantly learning and staying up-to-date with the latest trends and best practices in mobile development to ensure that the applications I build are of the highest quality.

I've edited and developed complex fastlane setups, that includes: 1. Setting up docker to be able to build the backend for integration tests. 2. iOS certificates using Match. 3. Deploy versions to TestFlight, AppCenter, Firebase using Bitrise, Jenkins && other. 4. Nice-have automation tips like post a message to slack when the build is done, have a link to the build so the QA team can install it directly on their phone.

Worked with Apple Retail, coding in different projects that involved App Store experiences. I contributed to different systems that consisted of multiple iOS devices connecting with each other, building a mesh of devices using Apple's proprietary technology. The devices are meant to be kept on the wall, so challenges regarding memory issues && performance had to be taken care of to ensure a smooth experience. The technologies used consist mainly on Swift, targeting iPhone and iPads.
