Priyanshu Kumar Paswan | Full-Stack & AI Developer

Web Development

Custom, high-performance web applications and websites engineered with React, Next.js, Node.js, and modern cloud technologies.

I engineer high-performance, scalable web applications and enterprise-grade websites built specifically to support business expansion and digital transformation. Every application is crafted from clean, semantic code with a focus on instantaneous load speeds, robust security protocols, and intuitive user experiences. By leveraging modern frameworks such as React, Next.js, Node.js, and TypeScript, I deliver solutions that seamlessly handle high traffic volumes while maintaining exceptional Core Web Vitals.

Key Deliverables:

• Sub-second load times engineered with code-splitting, tree-shaking, and modern bundling pipelines.
• 100% responsive fluid layouts optimized across mobile, tablet, desktop, and ultra-wide displays.
• Clean, modular, and fully typed component architecture (React 19 & TypeScript) built for long-term scalability.

Web Design

Clean, modern, and conversion-optimized UI/UX designs that captivate audiences and turn visitors into loyal clients.

I design intuitive, visually striking user interfaces (UI) and engaging digital experiences (UX) that reflect your brand identity and maximize conversion rates. Great design is not merely decoration—it is the strategic synthesis of visual hierarchy, psychology, typography, and friction-free user flows. From interactive wireframes to high-fidelity Figma design systems and production-ready CSS styling, I craft interfaces that leave a lasting impression.

Key Deliverables:

• Bespoke, premium visual identities tailored to your brand personality and industry positioning.
• Conversion-centered UX flows designed to reduce drop-offs and guide users directly to core calls to action.
• Comprehensive design systems including color palettes, typography scales, icon sets, and UI components.

Application Development

End-to-end full-stack web and SaaS applications built with secure APIs, scalable databases, and modern UI architectures.

From conceptualization and database schema design to cloud deployment and ongoing optimization, I build robust, full-stack web applications and SaaS platforms. Whether you need a customer management portal, an interactive business dashboard, or an AI-integrated workflow automation platform, I deliver secure, resilient, and maintainable software architectures that scale alongside your user base.

Key Deliverables:

• Complete end-to-end engineering covering responsive frontend, RESTful/GraphQL APIs, and database persistence.
• Enterprise-grade authentication with Google OAuth, JWT session tokens, and strict Row Level Security (RLS).
• Seamless integration with third-party APIs including OpenAI, Stripe, Cloudflare, Resend, and webhooks.

Database Development

Structured, high-performance database architectures ensuring absolute data integrity, lightning-fast queries, and effortless scaling.

Every high-performance web application depends on a robust, well-architected data layer. I design, optimize, and manage scalable SQL and NoSQL database infrastructures that deliver high-concurrency read/write throughput, consistent data integrity, and rapid query execution. Whether building a new relational schema from scratch, migrating legacy data without downtime, or indexing high-latency queries, I ensure your database operates at peak efficiency.

Key Deliverables:

• Optimized query performance and execution plans that reduce database latency to sub-50ms ranges.
• Normalized relational schemas and flexible document models tailored to specific operational access patterns.
• Robust data integrity enforced through foreign keys, check constraints, database triggers, and transactions.

WordPress Design

Custom, bloat-free WordPress websites built from scratch for lightning-fast speeds, top-tier SEO, and effortless content management.

I design and develop custom, high-speed WordPress websites that break free from slow, bloated templates and heavy page-builders. By building bespoke themes from scratch using clean PHP, JavaScript, and Tailwind CSS, I ensure your site achieves near-instant load speeds, impenetrable security, and flawless Core Web Vitals. Your team gets an intuitive, customized backend editor tailored specifically to your content needs, without confusing menus or fragile plugins.

Key Deliverables:

SEO Optimization

Technical on-page SEO, Schema structured data, and Core Web Vitals optimization to rank higher on Google and capture organic search traffic.

Having a visually impressive website is only valuable if your ideal customers can discover it. I provide comprehensive technical and on-page Search Engine Optimization (SEO) services that build a rock-solid foundation for long-term organic growth. By addressing technical crawlability, Core Web Vitals performance, semantic heading hierarchy, JSON-LD Schema structured data, and targeted keyword architecture, I help your business capture high-intent search traffic and outrank competitors.

Key Deliverables:

• Comprehensive technical SEO audit identifying crawl errors, canonical mismatches, and indexation blockers.
• Advanced Schema.org JSON-LD structured data implementation to capture Google Rich Snippets and Knowledge Panels.
• Core Web Vitals optimization resolving Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).

Website Speed Optimization

Deep engineering optimizations to slash page load times, achieve green Core Web Vitals, and maximize conversion rates.

Every millisecond of page load latency directly impacts your conversion rates and search rankings. Studies show that a 1-second delay can reduce conversions by up to 7% and cause over 50% of mobile users to abandon your site. I perform deep, code-level performance tuning across your frontend bundles, media assets, caching configurations, and server responses to ensure your website loads in under one second across all global locations.

Key Deliverables:

• Near-instant page load times with Largest Contentful Paint (LCP) under 1.2 seconds.
• Perfect Core Web Vitals compliance (LCP under 2.5s, INP under 200ms, CLS under 0.05).
• Significant reduction in JavaScript bundle sizes through dynamic imports and tree-shaking.
