Healthcare SaaS
PsychPlus — Healthcare SaaS Reliability
Tele-psychiatry & therapy platform, USA · Senior Software Engineer, Jan 2024–Present
PsychPlus needed to stabilize a patient- and provider-facing healthcare app spanning scheduling, payments, telehealth, and patient intake — while continuing to ship new features. The app's crash rate was a significant reliability problem.
What was done: systematic bug fixing and production hardening across the codebase; rebuilt and stabilized appointment scheduling (rescheduling, visit-type handling, specialty filtering); improved payment and insurance workflows including copay/co-insurance handling; implemented and refined HPI/pre-check-in flows with better validation; enhanced telehealth join-call logic and deep-link handling; introduced OTA update pipelines, QA automation, and TypeScript/code-quality cleanup (Sonar).
Result: crash rate reduced 92%, from 8% to 0.80%.
