A practical, evidence-backed breakdown of technical specialties, software architectures, and production capabilities proven across 12+ years of professional web engineering.
Shrikant Yadav specializes in Full-Stack MERN Development (MongoDB, Express.js, React.js, Node.js), Next.js App Router & Server Components Architecture, Multi-Tenant SaaS Engineering, and Web Performance Optimization (100/100 Core Web Vitals). His expertise is demonstrated through live, high-traffic products like Photocopywala (7,000+ daily users), DigitingCard, School CMS, and open-source NPM packages.
End-to-end full-stack development combining MongoDB schemas, Express/Node.js REST APIs, and React/Next.js frontend applications. Building secure JWT/OAuth authentication, role-based access control (RBAC), and efficient data aggregation pipelines.
Architecting modern web applications with Next.js 15/16 App Router, React Server Components (RSC), Server Actions, and Partial Prerendering (PPR). Optimizing data fetching waterfalls, streaming UI, and edge middleware.
Designing multi-tenant web applications with secure tenant isolation, custom subdomain routing via Edge middleware, automated tenant provisioning, and shared-database isolated-collection architectures.
Turning heavy web applications into sub-second, 100/100 PageSpeed powerhouses. Auditing JavaScript execution bottlenecks, optimizing Interaction to Next Paint (INP), and eliminating Cumulative Layout Shift (CLS).
Eliminating expensive backend image processing servers by executing heavy PDF rasterization, image compression, and passport photo formatting entirely in user browser threads via Web Workers and WebAssembly.
Structuring web data for both traditional Google SERPs and next-generation AI engines (Google AI Overviews, Perplexity, ChatGPT). Implementing deep Schema.org JSON-LD graphs and machine-readable llms.txt protocols.
