Snehasish Pradhan

Frontend Engineer with 5+ years of experience architecting and shipping scalable web and mobile products, and full-stack fluency in Node.js, NestJS, PostgreSQL, and REST API design. Co-founder and Lead Engineer of ByzWiz, a live multi-domain SaaS platform combining e-commerce, video commerce, and social networking, deployed across web (Next.js), iOS, and Android, with production-grade Core Web Vitals of LCP 0.29s, CLS 0.00, and INP 64ms. As the senior engineer owned end-to-end product engineering — from system design and API architecture through UI delivery.

Primary strength is frontend architecture and delivery; backend work in recent years has been limited to API design, integration, and light service maintenance rather than deep hands-on development.

Seeking

Frontend or Full-Stack (frontend-heavy) roles where product ownership and system design depth are valued.
