Ajay Karan Sharma
Architecting Next-Generation Web & Ecommerce Platforms
I am a Senior Web Developer, Shopify Plus Architect, and Full-Stack Consultant with over 12+ years of hands-on software engineering experience. Based in Himachal Pradesh, India, I partner directly with fast-growing DTC brands, high-GMV global merchants, enterprise teams, and ambitious local business owners worldwide.
Throughout my 12-year career, I have architected custom checkout UI extensions handling millions in monthly transactions, built sub-second Headless Hydrogen storefronts on Remix and Next.js, engineered bespoke ERP inventory sync middleware, and migrated legacy stores from Magento, WooCommerce, Squarespace, and Wix with zero downtime and 100% SEO preservation.
My engineering philosophy is rooted in craftsmanship, zero technical debt, and business profitability. I write clean, modular, and maintainable code that loads under 1 second, converts visitors into paying customers, and scales effortlessly as your business grows.
The 4 Pillars That Define My Work
I build web software with craftsmanship, rigorous testing, and zero technical debt.
1. Performance-First Focus
Every 100ms of page load latency costs conversions. I engineer sub-second mobile page loads, inline critical CSS, and purge bloated third-party scripts to hit 90+ Core Web Vitals.
2. Maintainable, Modular Code
No fragile hacks or messy spaghetti code. I build clean, modular components, strict TypeScript schemas, and documented architectures that scale smoothly with your team.
3. Data Integrity & Security
PCI-DSS compliance, HMAC webhook signature verification, and automated background retry queues ensure zero lost customer orders or corrupted data during traffic spikes.
4. Direct Senior Partnership
Zero junior hand-offs or agency middlemen. You communicate directly with a 12+ year Senior Architect who respects your deadlines, milestones, and budget.
