Sample interview questions
Describe a complex full-stack feature you owned from concept through production.

I would explain the product problem, technical design, API and data-model decisions, frontend implementation, testing strategy, deployment process, and the measurable outcome. I would also highlight trade-offs made with Product and how I monitored the feature after launch.

How do you design a scalable Node.js backend service using PostgreSQL?

I begin with clear domain boundaries and API contracts, then design normalized data models and indexes around expected query patterns. I use connection pooling, pagination, transactions where consistency matters, observability, and query analysis to address bottlenecks before scaling infrastructure.

How have you used AI tools in your daily engineering workflow?

I use AI tools to accelerate routine tasks such as drafting tests, exploring unfamiliar code, generating documentation outlines, and reviewing implementation alternatives. I validate all outputs through code review, automated testing, security checks, and my own understanding rather than treating generated code as authoritative.

What practices would you apply when building software for a HIPAA-regulated healthcare product?

I would minimize protected health information exposure, enforce least-privilege access, encrypt data in transit and at rest, maintain audit logging, and follow secure development and incident-response practices. I would also partner with security and compliance stakeholders to ensure architectural and vendor decisions meet applicable requirements.

How do you balance speed and quality in a 0-to-1 product environment?

I identify the smallest reliable solution that validates the core user need, make assumptions explicit, and use instrumentation to learn quickly after release. I protect critical areas such as security, data integrity, and observability while deferring nonessential abstraction until product signals justify it.
