Project details
I help SaaS and eCommerce businesses fix unreliable APIs, payment systems, and data sync issues that break in real usage. Most integrations fail not because of technology, but because they were rushed, lightly tested, or stretched beyond their original design. Common problems include failed subscription or recurring payments, webhooks that stop firing or duplicate events, login/session issues from expired tokens, and fragile automations in Zapier or Make.
During our consultation, I’ll review your integration setup, identify the root cause of the issues, and provide clear guidance on whether it can be safely fixed or if a partial rebuild is needed. You’ll leave with actionable recommendations, risk analysis, and next steps to stabilize your systems. I only add AI-based APIs when they genuinely improve reliability or internal automation, keeping your system simple and maintainable.
