Karthik Iyer

I’m a Senior Front-end Developer with full-stack experience, specializing in scalable web and mobile applications using React, React Native, Next.js, Remix, and TypeScript. I focus on frontend architecture, performance optimization, and building development workflows that keep releases fast and reliable.

At Techolution, I design and implement responsive UIs for products like a React-based customer support dashboard—integrating secure authentication (Firebase OTP) and analytics (Google Analytics) to drive funnel insights. I architect secure, scalable applications and improve engineering throughput by building CI/CD pipelines and implementing unit and integration testing with SonarCloud.

I’ve also delivered security-critical work, including a React Native banking app with MFA, KYC, and CDD, where I masked SSNs and encrypted PII to reduce takeover risk and servicing costs. Across key user flows, I enhanced performance using memoization, efficient rendering, and lazy loading—and scaled Next.js/Remix experiences with internationalization and localization.

I’m known for quickly adapting to new technologies and taking ownership under pressure, collaborating cross-functionally to deliver results. I leverage AI tools like Claude and ChatGPT to accelerate development, automate documentation, and improve team-wide code review and onboarding workflows—while maintaining strong engineering standards like accessibility, code reviews, and Agile SDLC.
