Kaushal Mishra
Senior Frontend Engineer
Kaushal Mishra is a Senior Frontend Engineer in Mumbai with 5.7+ years building production SaaS and AI-powered platforms in React, Next.js and TypeScript. Six products shipped across StoreApps and Enso Web Works, reaching 10,000+ users — real-time streaming UI, SSR and technical SEO, LLM integration, and frontend architecture.
Core competencies
Real-time & streaming UI
Token-by-token SSE interfaces that stay correct when a user switches conversations mid-response, remounts a component, or fires concurrent requests. Stream managers, optimistic state, graceful cancellation.
SSR & technical SEO
Server-rendered Next.js built to be found: per-route metadata, Open Graph previews, canonical structure, structured data, and Core Web Vitals treated as a requirement rather than a cleanup task.
AI product engineering
Multi-provider LLM layers with quota-aware fallback, tiered usage metering, intent routing, and sanitized Markdown rendering — so an outage at one provider is a routing decision, not an incident.
Frontend architecture
Modular client architecture on MVC and clean-architecture principles, split so a team can keep extending it a year later without a rewrite. Typed end-to-end, tested at the seams.
Design → production fidelity
Complete Figma systems converted into pixel-accurate, mobile-first production apps, including the design work itself across four SaaS sub-brands and their marketing surface.
Ownership & team leadership
Roadmap, sprint planning, bug triage, code review, and production releases — leading four-member cross-functional teams while staying the primary hands-on developer.
