WHAT ENGINEERING LEADERS SAY.
"Keithel Digital didn't just build a website; they fixed our entire digital bottleneck. The custom plugin they engineered saved our team hours of manual data entry every week."
"Finally, a development team that understands code architecture. They ripped out our slow page builder and delivered a custom WordPress theme that loads instantly with sub-second LCP."
"Their ability to build custom Shopify apps exactly to our spec was exactly what we needed to scale. Highly technical, extremely professional, and zero communication friction."
"We required strict bi-directional REST & GraphQL middleware connecting NetSuite to custom web applications. Keithel Digital delivered the pipeline on schedule with zero latency spikes."
CLEAR ANSWERS BEFORE YOU HIRE US.
Commercial page builders generate excessive, unoptimized CSS and JavaScript DOM depth, which directly harms your Google Core Web Vitals scores and mobile conversion rates.
Custom WordPress theme engineering utilizes clean, hand-coded PHP, modern CSS, and native Gutenberg blocks tailored specifically to your design. This results in a codebase that is up to 80% lighter, highly secure, effortless for your marketing team to edit, and capable of loading in under 1.5 seconds.
Yes. Relying on 10+ third-party Shopify apps inflates your monthly operational costs and injects conflicting render-blocking scripts into your store’s checkout path.
We engineer private, custom Shopify apps using React, Node.js, and GraphQL. Whether you need dynamic pricing rules, custom sizing tables, or bespoke ERP syncing, a single private app cleans up your admin dashboard and keeps your storefront lightweight.
Yes. For enterprises requiring maximum frontend speed and omnichannel content distribution, we build headless architectures. We pair decoupled backend CMS platforms (like WordPress or Strapi via REST/GraphQL APIs) with fast modern frontends built in React or Next.js.
Platform migrations carry severe SEO risks if handled incorrectly. Our migration protocol includes:
- ✓ Comprehensive URL & Metadata Mapping: Extracting all existing indexed URLs, meta tags, and canonical paths.
- ✓ 1:1 301 Redirect Implementation: Mapping old database permalinks directly to the new Shopify routing structure before launch.
- ✓ Schema & Catalog Preservation: Ensuring structured product data, reviews, and customer accounts migrate seamlessly without broken links or 404 spikes.
We optimize web performance at the infrastructure level rather than applying superficial fixes. Our optimization stack includes:
- ✓ Refactoring database queries to eliminate memory leaks.
- ✓ Replacing heavy JavaScript libraries with vanilla JS or native browser APIs.
- ✓ Implementing server-level caching, WebP/AVIF image delivery, and critical CSS inline rendering.
- ✓ Minimizing Layout Shifts (CLS) and First Input Delay (FID/INP) for desktop and mobile viewports.
Yes. Keithel Digital is a formally registered Indian business entity operating under full GST compliance. We issue structured, tax-compliant B2B invoices, official project scopes, and non-disclosure agreements (NDAs) for both domestic Indian enterprises and international corporate clients.
You retain 100% full ownership of all custom source code, custom theme templates, private plugins, graphics, and database assets upon final project clearance. We provide clean Git repository handoffs with full documentation and zero proprietary vendor lock-in.
We offer structured monthly Service Level Agreements (SLAs) tailored to your operational needs. Our retainer services include proactive core/plugin security patching, automated daily off-site backups, uptime monitoring, performance regression auditing, and priority developer hours for new feature rollouts.
