Senior software engineer building scalable fullstack products with React, Node, and SQL.
United StatesWhat I'm looking for
I’m a Senior Software Engineer with 10 years of experience building scalable fullstack products across frontend and backend systems. I bring deep, hands-on expertise in React.js, TypeScript, Node.js, Express.js, and SQL-backed services—focused on shipping reliable features that hit business outcomes.
In my recent roles, I’ve architected React.js and TypeScript feature work, tightened UX consistency across complex workflows, and reduced front-end defects by 31%. I integrate axios-based APIs with resilient error handling, optimize responsive layouts with CSS and styled-components, and harden critical flows with Jest and Mocha to increase pass coverage and catch regressions before release.
I’m equally driven by performance and maintainability: I model and optimize PostgreSQL queries to cut page latency, tune browser rendering and server response hot paths, and streamline remote collaboration with clear API behavior and rollout documentation. I mentor engineers on reusable component patterns, testing discipline, and clean service boundaries, partnering with designers, product managers, and multicultural teams to deliver measurable impact.
