With over 5 years of full-stack and backend engineering experience, I have a proven track record of setting technical direction and leading cross-functional teams to deliver complex, revenue-generating features.

I am particularly drawn to Consensys's mission to make the decentralized web accessible to all. I thrive in remote-first, collaborative environments and am passionate about mentoring engineers and fostering a culture of high code quality and innovation. I look forward to the opportunity to contribute to MetaMask's growth and help shape the future of money movement in Web3. Copy ### Sample Interview Questions Describe a time you had to make a difficult architectural decision for a payment system. What trade-offs did you consider and what was the outcome?At my previous job, we were building a real-time payment processing system. I had to choose between a monolithic approach for simplicity and a microservices architecture for scalability. I chose microservices to handle high transaction volumes, but we invested heavily in monitoring and circuit breakers to manage complexity. The outcome was a system that scaled to handle a 10x increase in transactions with 99.99% uptime.How would you approach mentoring a junior engineer who is struggling with understanding the complexities of blockchain and payment integrations?I would start by assessing their current understanding and then pair them with a simpler, well-documented component of the payment flow. I'd schedule regular one-on-one sessions to review their work and answer questions, gradually increasing the complexity. I'd also encourage them to participate in design discussions and code reviews to learn from the team. Providing clear, incremental goals helps build confidence.What strategies do you use to ensure the reliability and observability of distributed systems handling financial transactions?I implement comprehensive logging, monitoring, and alerting using tools like Datadog or Prometheus. I design systems with graceful degradation and fallbacks for third-party API failures. I also conduct chaos engineering experiments to test resilience. For transaction integrity, I ensure idempotency and implement compensating transactions for rollbacks. Regular post-mortems help continuously improve reliability.Can you explain how you would design a feature to allow users to buy cryptocurrency with fiat currency, integrating with multiple payment providers?I would design an abstraction layer for payment providers, defining a common interface for API calls and webhooks. The core logic would handle user authentication, check compliance (KYC/AML), and initiate transactions. I'd use a state machine to track transaction statuses and ensure idempotency. Each provider integration would be a module, allowing easy addition of new providers. The system would include rate limiting, fraud detection, and fallback to alternative providers if one fails.How do you stay current with the rapidly evolving Web3 and blockchain ecosystem, and how have you applied new knowledge to your work?I follow key developers and projects on Twitter, read whitepapers, and attend conferences like Devcon. Recently, I learned about account abstraction (EIP-4337) and proposed integrating it into our wallet to improve user experience by eliminating seed phrases. I led a proof-of-concept that reduced onboarding friction by 30%. I also contribute to open-source projects to deepen my understanding and share knowledge with the community.
