Triet Le

iOS Developer

Brings ideas to life with code.

From innovative startups to established brands, I have a proven track record of delivering intuitive and visually appealing apps that cater to the unique demands of diverse audiences.


Music & Podcasts app

I spearheaded the transition from Objective-C to Swift and SwiftUI, revitalizing core UI components of the music player and playlist for an enriched user experience.

My shift from Storyboard to SwiftUI optimized application architecture, while I remained committed to identifying performance issues and championing code quality through meticulous reviews.

Introduced over 10 new payment methods tailored for four specific countries: Germany, Finland, Japan, and regions in Asia. I was in charge of integrating these payment methods globally within the app.

Managed all the UI updates related to payment processes, ensuring users have a seamless experience when checking out.


Food delivery app

I had the privilege of leveraging technology to aid individuals with rare diseases. My role spanned beyond coding. I was instrumental in shaping the app's architecture, ensuring it was both robust and scalable, primed to accommodate our innovative features. The application allowed patients to record, visualize, and monitor treatment data, and I took pride in spearheading the integration of real-time data sharing with healthcare teams.

The stringent standards of the health tech industry coupled with the dynamism of a startup made every day at Florio an exhilarating challenge. In essence, my journey at Florio wasn't merely about building an app, but crafting a lifeline for those with rare diseases, blending healthcare with technology.


Digital Health-tech app

  • Collaborate with cross-functional teams to create and design an iOS application for blockchain wallet. This involves a detailed process of defining the app's core functionalities and ensuring that it aligns with the company strategic objectives. The focus will be on developing an application that is both user-friendly and efficient, tapping into the latest trends and technologies in the blockchain space.

  • In the development phase, the priority will be to implement and maintain code that is clean, efficient, and reusable. This requires working in close collaboration with the design and product teams to ensure that all requirements are accurately translated into technical solutions. Additionally, there will be a significant emphasis on partnering with blockchain developers to seamlessly integrate the app with underlying blockchain infrastructure, ensuring a robust and secure user experience.


Blockchain Wallet App


Shopping app

Played a pivotal role in enhancing the mobile experience. My implementations, including the introduction of NDA features for a new store app that allowed employees to manage stocks, received commendable feedback and accolades.

Undertook a significant refactoring task, transitioning the app from an MVC architecture to a more modern and efficient MVVM-State model.

Collaborated with a diverse team of developers, designers, QA and stakeholders to transform requirements into clear action plans.

Tackled technical challenges in both iOS and Android, using languages like Swift, Objective-C, Java, and Kotlin.

Provided direction on system architecture, application design, and data migration strategies.


InApp Payment SDK


Audio books & Podcasts app

Involved the extraction of the audio engine from the main codebase, transitioning it into a separate SDK. This strategic move streamlined the primary app functions, while also creating a modular and scalable audio framework that can be potentially utilized across multiple projects.

Collaborated closely with the team to ensure this extraction not only improved the app's efficiency but also retained its top-notch audio quality for listeners

Integrating 2 major platforms: Philips Hue and Tado smart sensors. With Philips Hue, I enabled users to control their smart devices directly via the Tibber app.

Simultaneously, the Tado smart sensor API integration allowed for seamless control and display of sensor data within the app. These integrations transformed the Tibber experience, merging energy management with comprehensive home automation, thereby reinforcing the company's commitment to a unified and innovative smart home ecosystem.
