What I'm looking for

I want to lead full-stack and backend work—designing scalable architectures, improving performance and security, and mentoring teams—while collaborating with product and engineering in modern cloud environments.

I’m a Senior Software Engineer with 10+ years building applications and backend systems across modern web and cloud environments. I focus on high-performance services, clean architectures, and maintainable codebases using modern development stacks.

At Workday (Nov 2024–Present), I lead full-stack feature development with React, Redux, Next.js, Node.js, and Java-based backend services. I’ve designed microservices-based solutions with RESTful APIs and GraphQL, applying clean architecture principles, JWT/OAuth2 authentication, and secure service communication patterns.

I’ve helped improve delivery and reliability through practical engineering: supporting AWS and Kubernetes deployments with CI/CD automation (GitHub Actions and Jenkins), improving deployment reliability by 30%. I’ve also optimized performance with caching, lazy loading, query optimization, and horizontal scaling—improving reliability under high-traffic workloads by 25%.

I’m committed to code quality, security, and collaboration. I mentor junior developers, contribute to architecture discussions, and support robustness across accessibility, web performance, and SEO—backed by automated testing with Jest, Playwright, and Postman.
