About Francesc Vilariño

Software Architect, Android Engineer, and Technical Leader

With a career spanning 28 years in software development, including 17 years dedicated to Android, I have a proven track record of delivering world-class apps for some of the world’s most renowned companies. I’ve had the privilege of engineering mobile solutions for brands like eBay, Warner Bros Discovery, Reddit, Nike, Lululemon, Dell, and VMware, contributing to high-impact apps such as Bleacher Report, NBA, and March Madness Live.

I specialize in building robust Android applications using a modern stack: Kotlin, Jetpack Compose, MVI, GraphQL, and Dependency Injection. Whether I’m architecting a new system from the ground up or optimizing performance for millions of users, I focus on delivering clean, maintainable code that stands the test of time.

Driving Engineering Excellence

I believe that great software isn’t just about solving today’s bugs; it’s about building resilient systems that empower teams to move faster. My approach to engineering excellence centers on architectural integrity and maintainable patterns. By championing Modern Android practices, including Jetpack Compose, MVI, and Clean Architecture, I help organizations reduce technical debt and accelerate release cycles. I don't just deliver features; I establish the automated testing suites, CI/CD pipelines, and documentation standards that ensure long-term code health and developer velocity.

End-to-End Product Ownership

A world-class app requires more than just a clean codebase; it requires a deep alignment with the product vision. I take pride in being a product-minded engineer, collaborating closely with designers and stakeholders to translate complex business goals into seamless user experiences.

From the initial discovery phase to post-launch optimization, I take full ownership of the technical lifecycle. Whether it’s optimizing GraphQL for efficient data fetching in high-traffic environments or implementing real-time synchronization for sports and media platforms, I ensure that every technical decision serves the ultimate goal: a high-performance product that users love and businesses can scale.

Beyond the Code

My passion for problem-solving extends beyond the IDE. I am a lifelong learner with a background in Telecommunications from the Universitat Politècnica de Catalunya and the École Supérieure d'Électricité, a foundation that allows me to approach software through a lens of systems engineering.

When I’m off the clock, I find balance in the great outdoors, whether it’s the physical challenge of backpacking and hiking through the Pacific Northwest or the mental escape of a complex sci-fi novel. I bring that same sense of exploration and curiosity to every project I touch, always looking for the next mountain to climb in the world of mobile technology.

Independent Projects & Technical Labs

I maintain a set of apps on the Google Play Store that showcase my commitment to modern software principles:

Exposure Calculator: A utility for photographers to calculate equivalent exposures and long-exposure timers. This project focuses on precision logic and intuitive UI for specialized use cases.
Password Vault: A secure, no-frills credential manager built to demonstrate Clean Architecture. It features a modern stack including Jetpack Compose, Circuit, Metro DI, and Room, with optional Google Drive synchronization.

Let's connect

Whether you want to discuss modern Android architecture, chat about Jetpack Compose performance, or explore potential collaborations, I am always open to connecting with fellow engineers. Based in the Greater Seattle area, I enjoy engaging with the tech community and am passionate about mentorship and sharing knowledge.
