Senior Front End Developer / Full Stack Engineer

Fast interfaces. Clear architecture. Production discipline.

I build React and Next.js products that are not only polished, but measurable: performance-focused, maintainable, and backed by practical ASP.NET Core delivery.

Senior ownership with hands-on delivery.

I work where front-end quality meets business pressure: architecture, implementation, performance, QA collaboration, code standards, and full-stack integration.

I am a Full Stack Engineer with an Electrical Engineering background and 5 years of experience across front-end and back-end development. I focus on Next.js, React, TypeScript, ASP.NET Core, C#, .NET Core 3-10, REST APIs, EF Core, SQL, and Optimizely DXP.

My day-to-day work includes maintaining front-end architecture, enforcing code standards, reviewing code, supporting developers, coordinating with QA and business teams, and converting Figma and business requirements into reliable production features.

SpeedyHire performance optimization.

SpeedyHire is the largest project I have worked on. My contribution focused on improving heavy hiring workflows and reducing the cost of loading complex pages.

What changed

I optimized heavy web pages by greatly reducing HTML document weight and turning slow, complex page loads into a smoother, faster user experience.

I am responsible for the SpeedyHire front-end architecture and related technical aspects, including standards, implementation quality, code reviews, and performance-minded Next.js delivery across high-traffic hiring workflows.
