Project Overview

Mishe offers transparent, direct-pay healthcare with concierge support, connecting members directly to high-quality providers. I was brought in to modernize a legacy Firebase codebase, build internal tooling, and raise reliability, integrity, and delivery speed across web and Cloud Functions.

Challenges

  • Stabilize and modernize a large-scale Firebase (web/Cloud Functions) codebase to Node.js LTS.
  • Give Ops/Finance reliable dashboards for catalog, pricing, and Stripe operations with reconciliation and auditability.
  • Improve data integrity, release cadence, and observability as usage grew.

What I built

  1. Platform modernization — Upgraded Firebase runtimes to Node.js LTS, tightened TypeScript, and refactored hot paths to improve performance and release stability.

  2. Internal dashboards (React + MUI) — Built an admin dashboard and a reusable component library; standardized patterns and UX to speed delivery.

  3. Firestore data governance — Implemented a schema/usage analyzer and a dashboard-driven migration runner; integrated checks into CI to improve data integrity.

  4. Stripe finance ops — Delivered operations dashboards (charges, refunds, transfers, payouts) with reconciliation workflows and audit trails to reduce discrepancies and support compliance.

  5. CI/CD & developer experience — Set up CI/CD pipelines with GitHub Actions and Cloud Pub/Sub for PR checks, preview deploys, and in-dashboard deployment logs.

  6. Quality, reliability & performance — Added automated unit/E2E tests on PRs (Vitest/Playwright), structured logging/observability, caching, and targeted load tests to catch regressions early and keep latency low.

Impact

  • More reliable releases after LTS upgrade and CI checks; fewer regressions with contract tests.
  • Faster feature delivery via standardized components, previews, and clearer release workflows.
  • Higher data integrity from schema analysis and controlled migrations.
  • Reduced payment discrepancies and better auditability with Stripe reconciliation and trails.
  • Low-latency performance sustained under load with caching, batching, and query optimizations.

Collaboration

Partnered with DevOps on pipelines and logs; worked with Product/Ops/Finance to design admin workflows and reconciliation; performed peer reviews and shared best practices for testing, security, and observability.
