Case Study

Executive Summary

HealExpert—a fast-growing HealthTech start-up—sets out to be a “one-stop emotional-wellness companion.” Its early prototype proved market demand, yet the experience was fragmented: a basic website for content, a disconnected Android app for bookings, and Google Sheets for therapist scheduling. Investors and enterprise buyers demanded a unified, scalable, and AI-augmented platform that could deliver real-time triage, secure video therapy, and clinically validated outcomes.

Steady Rabbit mobilised a Micro-GCC squad (Core + Flex + Buffer) and, in just twenty weeks, delivered:

  • A HIPAA-ready cloud architecture with 99.96 % uptime
  • Web, iOS & Android apps sharing 92 % code—time-to-market 3× faster than native splits
  • A GPT-powered triage chatbot that resolved 63 % of Tier-1 queries automatically
  • Self-service therapist onboarding that cut go-live from 12 days to 36 hours
  • Day-1 activation uplift of 23 percentage points and session no-show reduction of 31 %

The project did not miss a single sprint milestone, allowing HealExpert to close a USD 8 million Series A round, land its first Fortune 1000 employee-wellness contract, and position itself for international expansion.

Client Profile & Business Context

  • Client
    HealExpert

    Mumbai-headquartered HealthTech company

  • Founded

    2020

  • Vision

    Democratise mental-health access through AI-guided triage, on-demand therapy, and personalised content

  • Funding

    Seed-funded (USD 2.4 M) before engagement

  • Operating Footprint

    India, UAE, and pilot users in UK & SEA

  • Pre-engagement Stack

    Angular web app, Android hybrid app, Firebase Realtime DB, Zoom free tier

  • Strategic Trigger

    Secure Series A and enterprise wellness contracts; need HIPAA/ISO compliance, measurable ROI for HR buyers

HealExpert’s leadership envisioned an integrated platform combining AI triage, tele-therapy, and continuous engagement. However, their patchwork tech stack could not scale, did not meet international data-privacy mandates, and delivered inconsistent UX. They required an engineering partner capable of owning the roadmap, de-risking compliance, and hitting a non-negotiable 20-week investor deadline.

Problem Statement / Key Challenges

Fragmented User Journey

  • Three separate codebases (web, Android, admin) → duplicated bugs, diverging features
  • Non-responsive therapist dashboard; 30 % of sessions double-booked

Scalability & Compliance Gaps

  • Firebase Realtime DB throttled at ~200 concurrent clients
  • No encryption at rest, no audit trails → HIPAA non-compliant

Manual Operations

  • Therapists onboarded via Google Drive; average cycle 12 days
  • No-show rate 40 % due to manual reminders

Lack of Personalised Engagement

  • Static content; no data-driven interventions
  • Users dropped off after second session; churn at day-14 was 38 %

Aggressive Time-to-Market

  • Series A pitch in 24 weeks; platform had to show KPI traction
  • Enterprise buyer PoC in parallel—SLA: < 500 ms p95 latency, ≥ 99.9 % uptime

Shift-Left Governance

7 Plan-Left Gates per user story—blocking Jira transition until persona, acceptance, risk, arch sketch, estimate, capacity, and test note are present.

SteadCAST dashboards surfaced lead indicators (Risk-High WIP%, Test-Note Coverage) daily.

30-minute weekly exec steering: demo, KPIs, burn, risk.

Methodology & Tooling

Agile Scrum

2-week sprints; Sprint 0 discovery + architecture.

Infrastructure-as-Code

Terraform, AWS CDK; blue-green EKS deploys.

DevSecOps

GitHub Actions, SonarCloud quality gate ≥ A, Snyk scans, OWASP ZAP.

React-Native + React (Next.js)

for cross-platform UI; GraphQL BFF for single endpoint.

Event-driven micro-services

(Go) on AWS EKS; user events piped to Kafka.

LLM Triage

OpenAI GPT-4 via LangChain; PHQ-9 and GAD-7 scoring; escalation rules.

Outcome: of Sprint 0: signed-off architecture, HIPAA control matrix, backlog sized at 94 SP/sprint capacity.

Solution Delivered

HIPAA-Ready Cloud Architecture

  • AWS EKS cluster with Fargate isolation per environment.
  • RDS PostgreSQL (encryption-at-rest) + DynamoDB for session tokens.
  • AWS KMS envelope encryption; CloudTrail + GuardDuty for audit.
  • Terraform Cloud stored state & produced SOC 1 evidence.

Unified Omnichannel Apps

  • React-Native reused 92 % code across iOS & Android, enabling parallel beta launch.
  • Next.js PWA delivered sub-1 s TTI on mobile web.
  • In-app WebRTC video (Daily.co) replaced free Zoom, ensuring PHI control and in-stream recording.

AI-Powered Triage & Content Engine

  • GPT-4 chatbot (LangChain) conducts empathetic intake, runs PHQ-9/GAD-7; auto-escalates high-risk scores.
  • Personalised content pipeline: vector search on pgvector suggests CBT modules; 63 % Tier-1 tickets auto-resolved.

Therapist Portal & Self-Service Onboarding

  • KYC verification, calendar sync (Google/Microsoft), and dynamic pricing in one flow.
  • Image-enhancement Lambda improves profile photos; average onboarding 12 days → 36 hours.

Engagement & Notifications

  • Event listeners trigger push, email, WhatsApp reminders; no-show rate 40 % → 9 %.
  • Gamified progress bar encourages completion of therapy homework; day-14 churn 38 % → 15 %.

Observability & Compliance Automation

  • Grafana Loki for logs; Prometheus for latency, error budgets.
  • SOC 2 & HIPAA artefacts auto-exported for auditors saved HealExpert 120 staff hours.
