Builds and integrations across a multi-client portfolio
A US digital agency needed a development team that could take work across their client portfolio and keep it running once it was live. Builds, migrations, integrations, and the production fixes that come after launch, across 10+ client sites.
- WordPress
- WooCommerce
- PHP
- JavaScript
- AWS
- Payment integrations
Why it mattered
Most of what goes wrong with a website happens after launch. A payment processor migration that quietly breaks recurring billing. An API that hits its rate limit on the busiest night of the year. The work that matters is being there to fix it properly, and fast.
“Slark Labs has been our go-to dev partner for over a year, delivering across multiple client sites including a campaign that helped our client raise nearly $1.2M at a single event. Fast, reliable, no drama, exactly what you need in an agency partner.”
Highlights
- Recovered 250+ failed payment subscriptions after a vendor-led migration between payment processors left recurring donations broken
- Built the event infrastructure for a non-profit fundraiser: seat and table booking, online check-in, and donation widgets for both one-off and recurring gifts, all running on the new processor
- Fixed a third-party API rate limit mid-event, live, while donations were coming in
- Integration rescue work across the portfolio: lending platform connections, lead routing, custom inventory systems, campaign landing pages
- WordPress builds, customizations, and ongoing maintenance across 10+ client sites
