What I'm looking for

I’m seeking a mid-level engineering role focused on building scalable web apps, performance optimization, CI/CD and automation within collaborative teams that value measurable impact and reliable delivery.

I am a full-stack developer with 3+ years building, deploying, and maintaining production web applications using React, Next.js, Node.js, TypeScript, and AWS. I deliver scalable, business-driven solutions across frontend, backend, and cloud infrastructure with an emphasis on performance and reliability.

At my most recent role I built and maintained production React and Next.js applications for 200+ users, implemented CI/CD pipelines with GitHub Actions and AWS CodePipeline to reduce release cycles by 40%, and optimized API response times and page load performance. I also developed TypeScript-based component libraries, custom WordPress themes and plugins, and automated workflows using AWS Lambda and Make.

I bring strong operational discipline, a focus on performance optimization and automation, and a collaborative mindset that ties engineering work to measurable business outcomes. I’m motivated to join teams where I can improve reliability, accelerate delivery, and contribute to scalable product experiences.
