Figures as published at sapun.com.np.
Google Ads and Meta Ads managed against revenue rather than clicks - $170K+ in spend, 100+ campaigns, and a 27% average ROAS lift across the accounts under management. Paid acquisition work includes a 3.1x ROAS engine at a 42% lower cost per lead.
The discipline this site is built out of. Crawlability, indexation, structured data, Core Web Vitals and the answer-engine surface that now sits alongside them. One e-commerce build reached 2.4x organic traffic with a 38% conversion lift.
Next.js, React, Laravel, Flutter, Node, MySQL, PostgreSQL and Redis, deployed on Vercel and AWS. 60+ websites delivered, 90+ Lighthouse scores across the portfolio.
HubSpot, GoHighLevel and Zoho implementations alongside custom CRM, ERP and HRM platforms. An enterprise CRM build cut the sales cycle by 40% and tripled reporting speed; a healthcare system cut administrative time by 60% at 99.9% uptime.
Automation that removes manual work rather than relabelling it, and the AI-visibility engineering that this validator exists to measure - AEO and GEO, the rules that decide whether an answer engine can read and cite a business at all.
GA4, BigQuery and Looker, wired so that spend, traffic and CRM data resolve to one number a business owner can act on. Turning that data into measurable revenue growth is the stated point of the work.
