Muralitharan V

Senior Front-End Engineer with 4+ years of experience building scalable, high-performance web applications for products serving tens of thousands of users. Specializes in Server-Driven UI (SDUI) architecture, real-time WebSocket systems, and data-fetching optimization. Deep focus on Core Web Vitals (LCP, FID, CLS) and measurable performance outcomes.

Proven ability to own CI/CD pipelines end-to-end and drive engineering culture improvements — from linting standards to TypeScript adoption. Career-changer from Mechanical Engineering, bringing strong systems-thinking fundamentals to complex frontend architecture challenges.

Senior Front-End Developer at Siam Computing (2022-12 – Present)

• Architected a Server-Driven UI (SDUI) system enabling product and design teams to launch new UI modules without front-end deployments — reducing feature release cycle time by ~40% and decoupling release schedules across teams. Designed the rendering engine to be stateless and cache-friendly, providing a clear path to support 10x traffic growth without architectural changes.
• Achieved a 35% reduction in redundant API calls and cut average page load from ~3.2s to ~1.4s by overhauling React component rendering and TanStack Query caching strategies. Tracked improvements using Core Web Vitals (LCP reduced by ~0.8s, CLS held to <0.05), ensuring alignment with Google's performance benchmarks.
• Built and maintained WebSocket-based real-time data layers for live dashboards, sustaining concurrent data streams with <100ms update latency. Designed the system to handle connection pooling and graceful reconnect logic, ensuring reliability under high-concurrency loads.
• Improved GitLab CI/CD pipeline by introducing automated test gates, parallel build stages, and enforced linting via ESLint config standardized across the engineering org — cutting average deployment time by 25% and eliminating manual steps.
• Drove TypeScript adoption across new modules company-wide, reducing runtime errors and improving onboarding speed. Raised test coverage from ~40% to ~75% using Jest and React Testing Library, and introduced E2E and visual regression test suites via Cypress to prevent UI regressions across releases.
• Acted as technical lead for a team of 2–3 junior developers: conducted structured code reviews, defined and documented front-end best practices, and mentored engineers from mid-level to independently owning features — improving team-wide PR quality and reducing review cycles.
• Collaborated directly with product owners to translate Figma designs into pixel-accurate, accessible React components, contributing to WCAG 2.1 AA compliance across core product surfaces.

Front-End Developer at Siam Computing (2021-10 – 2022-11)

• Built scalable, component-driven UI architecture for multiple client-facing products using React.js and TypeScript, contributing to a codebase serving 20,000+ monthly active users across diverse business verticals.
• Integrated REST and GraphQL APIs with structured error handling and loading state management, measurably improving perceived reliability across data-heavy screens and reducing user-facing error rates.
• Implemented Tailwind CSS design systems across projects, standardizing styling patterns and reducing per-feature CSS authoring time by ~30%, enabling faster design iteration.
• Identified and resolved performance bottlenecks — including unnecessary re-renders and bundle bloat — using Chrome DevTools and Webpack Bundle Analyzer, achieving a 20% improvement in Time to Interactive (TTI) and meaningful gains in Core Web Vitals scores.
• Wrote unit and integration tests using Jest and React Testing Library, achieving and maintaining 60%+ coverage on critical UI modules, with a focus on testing user flows and edge cases.
