I’m a senior software engineer with over 7 years of experience developing high-performance web applications. My expertise spans Ruby on Rails, ReactJS, and cloud infrastructure, and I enjoy turning complex requirements into scalable, reliable systems. I’ve delivered core product features across multi-platform experiences, including architectures like conversation continuity to improve usability and reduce session drop-offs. I’m hands-on with designing RESTful APIs, GraphQL schemas, and Rails controllers for high-availability and performance. Across my roles, I’ve focused on stability, user experience, and measurable improvements—profiling performance bottlenecks, optimizing API response times, and enhancing scalability. I’ve also built internal dashboard workflows to improve operational efficiency and collaborated closely with cross-functional teams, including ML and QA. From payment integrations (Stripe, ApplePay) and third-party APIs (Google APIs) to end-to-end reliability with RSpec, Jest, and Cypress, I build with quality and maintainability in mind. I’m especially motivated by scalable systems design, performance optimization, and shipping robust features that teams can confidently run in production.
