Architected and developed integrations with third-party APIs, exposing endpoints and webhooks so customers can consume services programmatically. Implemented resilient backend functionality in Node.js with production practices including idempotency, rate limiting, and concurrency control. Contributed to frontend development using React and state management with Redux, and used feature flags to control and gradually roll out new functionality in production.

Worked on systems composed of bank-employee and client applications, including broker workflows and property registration and browsing. Also contributed to internal solutions at Tokio Marine, including SQL query execution across multiple corporate databases and an HTTP gateway for routing calls between internal systems. Participated in development of the Bradex Express platform using Angular and a micro-frontends architecture, wrote unit tests with Jest, and helped build additional AI- and messaging-related services using Spring Boot, RabbitMQ, and integrations with SMS and MS APIs.
