Key Skills

React Native JavaScript TypeScript API Design WebSockets Next.js UI/UX Mobile Development Crypto Mentoring

I am writing to express my strong interest in the Senior Software Engineer, React Native position at Kraken. With over 6 years of experience building high-performance mobile applications and a deep passion for crypto, I am excited about the opportunity to contribute to the Pro team's flagship trading platform.

My expertise in React Native, TypeScript, and API design aligns perfectly with your requirements. I have a track record of delivering scalable, fault-tolerant systems and mentoring junior engineers to raise the bar on code quality. I thrive in fast-paced environments and am committed to shipping quality work that makes a real impact.

I am particularly drawn to Kraken's mission of accelerating global crypto adoption and its strong engineering culture. I look forward to the possibility of bringing my technical skills and crypto knowledge to your team.

Thank you for considering my application. I am eager to discuss how I can contribute to Kraken's success.

Can you describe a complex React Native application you've built from scratch? What were the key architectural decisions and challenges?
I built a trading dashboard with real-time data updates. Key decisions were using Redux for state management, WebSockets for live data, and implementing a custom caching layer. Challenges included performance optimization for large datasets and ensuring smooth navigation.
How do you ensure code quality and maintainability in a fast-paced environment?
I advocate for code reviews, automated testing (unit, integration, and E2E), and adherence to coding standards. I also believe in continuous refactoring and documentation to keep the codebase clean.
Describe your experience with API design and security in mobile apps.
I've designed RESTful and GraphQL APIs with token-based authentication and OAuth2. I ensure data encryption in transit and at rest, and follow best practices like input validation and rate limiting.
How do you approach mentoring junior engineers?
I pair program on complex tasks, provide constructive feedback, and encourage them to take ownership of features. I also conduct tech talks and share resources to foster learning.
Tell me about a time you had to make a trade-off between shipping speed and quality. What did you decide?
In a previous project, we had a tight deadline for a critical feature. I prioritized core functionality and deferred non-essential polish, but ensured thorough testing of the core path. We shipped on time and later iterated on enhancements.
