Frequently Asked Questions
Everything You Need to Know
I specialize in bespoke WordPress development, custom Shopify Liquid stores, high-converting landing pages, speed optimization, website security hardening, and custom API/CRM integrations. All hand-coded without bloated visual page builders.
High-converting landing pages are typically delivered in 3 to 5 business days. A custom WordPress or Shopify store takes between 2 to 4 weeks depending on the number of unique templates and custom integrations required. I commit to clear timelines before we start.
No. By default, I build pure hand-coded PHP child themes and lightweight templates. This guarantees sub-second load times, clean code architecture, 90+ Core Web Vitals, and zero plugin vulnerability bloat. If you need content editing, I set up clean custom fields via ACF Pro or Gutenberg blocks.
Yes! I regularly perform forensic malware removals, patch exploited vulnerabilities, and optimize heavy websites down to sub-1s load times. For emergencies, WhatsApp me directly for same-day triage.
Standard projects operate on a 50% upfront deposit to begin development and 50% upon final approval prior to live launch. For larger builds, milestone-based installments are available. I accept Bank Transfer, UPI, and international wire / card payments.
You communicate directly with me via WhatsApp, Google Meet, or Email. You get direct access, prompt responses during working hours, and regular screen-recorded video updates showcasing development progress on staging.
