Case Studies

Real engineering, real outcomes

In-depth looks at production work — the problem, what was done, and the result.

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%.

EdTech SaaS

Cialfo — Scaling an EdTech SaaS Platform

College application management platform, Singapore · Senior React Native Developer, Mar–Dec 2023

Cialfo needed to deliver new features on aggressive timelines for a college-application tracking platform used by thousands of students and counselors, without sacrificing performance or stability.

What was done: architected high-performance React Native features with a responsive, optimized UI; managed complex application state using Redux Toolkit and Redux Saga; contributed to CI/CD pipelines and App Store release processes; worked closely with product and design to ship under tight deadlines.

Result: features shipped to a platform serving thousands of students and counselors, on schedule.

Result: multiple production apps shipped across separate codebases for international clients.
