Senior Software Engineer at rtCamp · Professional WordPress engineer since 2017 · Verified Expert WordPress Developer at Toptal

Biratnagar, Nepal · sagartamang.com.np

I'm a senior software engineer with nearly a decade of experience building and customizing WordPress at scale. I've spent my career working on both sides of the ecosystem — product engineering for WordPress-focused companies and direct contributions back to the open source projects I depend on. I currently work at rtCamp, and previously at ThemeGrill.

Beyond my day job, I contribute to WordPress core, organize community events, translate WordPress into Nepali, and share my experience through technical writing.

• Comments — credited in the commit hardening comment validation before and after data is filtered (changeset 59267)
• Twenty Twenty theme — credited in the font-size fix for Code blocks and preformatted elements (changeset 58960)

• Bug reports & docs — filed ticket #63384 (Content-Disposition inline filenames ignored by download_url()) and reported broken reference links in the WordPress developer documentation

Merged contributions to WooCommerce core, shipped in versions 4.3.0, 8.3.0, and 8.4.0:

Multi-vendor marketplaces & commerce customization:

• Dokan order splitting — fixed order splitting when orders containing products from multiple vendors are created from the admin dashboard instead of the storefront (write-up)
• Vendor-based product availability — made products purchasable only within a vendor's opening and closing hours (write-up)

I regularly extend WooCommerce through hooks, custom order/checkout logic, and plugin integrations for client projects.
