What I'm looking for

I am looking for a role building user-centric web applications where I can contribute React/Node.js expertise, work in Agile teams, and focus on testing, CI/CD, and accessibility.

I am a software developer focused on building maintainable, accessible, and high-performance web applications using React, Node.js, and TypeScript.

I have delivered single-page applications, RESTful APIs, and microservices across financial and enterprise domains, contributing reusable UI components, backend services, and migrations.

I emphasize testing, CI/CD, and accessibility—implementing unit and integration tests, automated accessibility checks, and pipelines with Jenkins and GitHub Actions to improve reliability and deployment velocity.

I thrive in Agile/Scrum environments, collaborate closely with product and business teams, and provide production support and troubleshooting to ensure business-critical systems remain performant and resilient.
