Frequently Asked Questions
Everything you need to know about our engineering standards, timelines, and deliverables.
How does Tellvok contractually guarantee sub-1.2s Core Web Vitals? +
We architect systems using Astro Islands. Rather than shipping megabytes of monolithic JavaScript bundles, public marketing pages compile directly to static HTML at the edge. Client-side JavaScript only executes within isolated interactive islands when visible in the viewport, ensuring zero main-thread blockage.
Do you hand over full code and design ownership upon completion? +
Yes, 100%. Upon project completion, all intellectual property belongs to you. We transfer the complete Git repository, Figma design files, database schemas, and documentation with zero vendor lock-in or recurring proprietary licensing fees.
Can this integrate with our existing CRM, ERP, and payment systems? +
Yes. Our hybrid SSR endpoints seamlessly interface with Salesforce, HubSpot, Stripe, Shopify, SAP, and custom REST/GraphQL services using signed server-side credentials and webhooks.
How long does a custom web platform project take to launch? +
A standard custom platform takes 4 to 8 weeks from kickoff to production cutover. We work in disciplined agile sprints with staging demos provided every Friday for transparent milestone feedback.
