With a proven track record of building scalable fullstack applications from the ground up, I thrive in fast-paced, 0-to-1 environments where I can drive architecture and deliver impactful features. My expertise in React and Kotlin, combined with deep experience in distributed systems and event-driven architectures, aligns perfectly with the technical demands of this role. * I have successfully launched MVPs and scaled them to handle high-volume production loads, collaborating closely with cross-functional teams. * I am passionate about leveraging AI tools to accelerate development and foster a culture of innovation, as highlighted in your job description. I am eager to bring my ownership mindset and collaborative approach to help Toast expand into new industries. I look forward to discussing how I can contribute to your team. Sincerely, [Your Name] Copy ### Sample Interview Questions Describe a time you built a product or feature from scratch (0 to 1). What was your approach and how did you handle ambiguity?I led the development of a new payment processing module for a retail platform. Starting with user research and prototyping, I iterated quickly with stakeholders. I focused on a minimal viable feature set, prioritized based on impact, and used continuous feedback loops. This resulted in a successful launch within 3 months, with 98% uptime from day one.How do you approach frontend architecture decisions for a new project? Can you give an example of a pattern you've advocated for?I typically start by defining component hierarchy and state management needs. In my last project, I advocated for a compound component pattern to improve reusability and maintainability. This allowed multiple teams to contribute without breaking each other's work, and reduced code duplication by 30%.Explain how you would design a scalable event-driven system for real-time order updates in a high-velocity restaurant environment?I would use an asynchronous messaging queue (e.g., Kafka or RabbitMQ) to decouple order ingestion from processing. Events like 'order placed' would trigger services. For frontend, I'd use WebSockets to push updates. I'd ensure idempotency and retry logic for reliability. This architecture handles spikes during peak hours without overload.How do you ensure code quality and resilience in a fast-paced startup-like environment?I enforce code reviews, unit/integration tests, and automated CI/CD pipelines. I also advocate for feature flags to gradually roll out changes and monitor metrics. In previous roles, this reduced production incidents by 40% while maintaining velocity.How have you used AI tools to improve your development workflow? Share a specific example.I integrated GitHub Copilot into my daily workflow, which accelerated boilerplate code generation and unit testing. For a recent project, I used it to generate API endpoint handlers, reducing development time by 25%. I also used AI-based code analysis to identify potential performance bottlenecks early. Location(s): US (remote), Boston (hybrid), or New York (hybrid) Years spent building on the restaurant front lines taught us how to build for speed, reliability, and complexity. Built for the dinner rush, our cloud-based platform and tough hardware now power high-velocity operations beyond restaurants. Join us to expand Toast’s impact to other industries – helping all kinds of business operators delight their customers, do what they love, and thrive. Bready* to make a change?
