Sushil Parajuli

I would like to introduce myself as an experienced Senior Software Engineer (Front-end) with over 10 years of crafting accessible and performant web applications. I focus on translating product intent into resilient interfaces that scale—balancing delivery speed with code quality, user experience, and security.

Strengths include design system architecture, Core Web Vitals optimization, WCAG 2.1 accessibility, secure authentication & CSP integration, testing strategy (unit → E2E), and cross‑functional collaboration that lifts team maturity.

Focused on building scalable, secure frontends that help teams ship fast without sacrificing quality: Next.js + TypeScript with semantic HTML5/CSS3 and a reusable design system; multilingual, RTL‑capable experiences; Core Web Vitals–driven performance (SSR/ISR, code‑splitting, edge caching); Sentry‑based observability and error tracking; and CI/CD, feature flags, and automated tests—aligned with WCAG AA, CSP/OWASP, and privacy‑by‑design best practices, including OAuth 2.0/OIDC SSO.
