What I'm looking for

I seek senior full-stack roles where I can build scalable, user-focused applications, mentor teams, work in Agile environments, and leverage cloud-based CI/CD pipelines.

I am a Senior Full Stack Developer with over 9 years of experience building scalable, high-performance web applications across e-commerce, finance, and healthcare. I specialize in React frontends, Node.js/Express backends, and cloud deployments on AWS.

I architect and implement REST and GraphQL APIs, design database schemas using MongoDB/PostgreSQL, and create reusable UI components with a focus on performance, TDD, and CI/CD. I have led integrations with payment systems like Stripe, implemented serverless solutions, and deployed multi-tenant platforms.

I work well in Agile, cross-functional teams, mentor junior engineers, and continuously learn new JavaScript technologies to deliver secure, user-centric products that align with business goals.
