LetsGetChecked operates a vertically integrated telehealth engine combining at-home diagnostics, clinical consultations, and pharmacy fulfillment. When corporate clients needed to navigate urgent return-to-work protocols, Elementica engineered an enterprise multi-tenant extension on top of their existing consumer platform.
Healthcare/Telehealth/USA
Full data isolation — strict multi-tenant security guarantees per employer without backend logic duplication
Algorithmic risk engine delivering automated real-time workforce health signals, replacing manual tracking spreadsheets
Zero-downtime rollout — enterprise B2B capabilities deployed seamlessly over active B2C infrastructure
Client context
LetsGetChecked is a leader in direct-to-consumer at-home healthcare, offering end-to-end diagnostic services from kit manufacturing to CLIA-certified lab testing and telehealth consultations. Historically built to serve individual consumers ordering standalone tests, the core architecture excelled at processing single-patient workflows.
When the COVID-19 pandemic disrupted enterprise operations worldwide, corporate employers faced an urgent mandate: implement scalable health screening, automated kit distribution, and return-to-work compliance protocols across distributed workforces. LetsGetChecked had the medical infrastructure and FDA EUA-authorized test kits, but lacked the enterprise-grade B2B multi-tenancy layer needed to manage corporate workforces collectively.
The challenge
Extending a consumer-facing telehealth monolith into an enterprise workforce management system under extreme time pressure presented complex engineering requirements:
- Strict B2B Data Segregation: Each corporate client required total isolation of employee health data (Protected Health Information / PHI) to meet legal, HIPAA, and enterprise security standards, preventing cross-tenant data leaks.
- Centralized Clinical Efficiency: While tenant data needed to remain strictly isolated, the backend coordination layer for medical providers, lab processing, and shipping logistics had to stay unified to prevent compounding operational overhead.
- Actionable Risk Signals: Raw laboratory PCR test results needed to be ingested, anonymized, and aggregated into real-time health risk metrics so corporate HR leaders could make instantaneous, data-driven return-to-work decisions.
Elementica's role
Elementica joined as the lead software engineering unit responsible for designing and deploying the enterprise multi-tenant layer. We architected the tenant isolation framework, developed algorithmic risk-scoring workflows, integrated automated lab pipelines, and built executive-facing compliance dashboards.
The solution
Isolated Multi-Tenant Architecture with Centralized Orchestration
We engineered a logical multi-tenancy layer on PostgreSQL and AWS. Using tenant-aware access control lists (ACLs) and row-level security policies, each employer's HR team accesses a securely partitioned dashboard. Meanwhile, the underlying provider orchestration engine processes kit dispatches and lab results asynchronously through a single unified microservice layer, ensuring zero duplication of clinical logic.
Automated Predictive Risk Navigation Engine
Instead of forcing corporate administrators to parse thousands of individual laboratory receipts, we built a risk-assessment engine. The system ingests self-reported symptom questionnaires and lab results in real time, calculating workforce risk indices. Automated trigger flows alert medical support teams for immediate follow-up care while flagging safety risks to HR managers.
Executive Compliance & Analytics Dashboards
We developed a React-based administrative suite that provides company leaders with aggregated, HIPAA-compliant visual telemetry. HR managers can track testing compliance rates, monitor active workforce safety metrics, and issue bulk kit dispatches across regional offices without gaining unauthorized access to private clinical consultation notes.
Engineering decisions that mattered
Logical tenant partitioning over isolated database instances
When designing multi-tenancy under tight launch deadlines, spinning up isolated database instances per client adds immense DevOps friction and costs. We opted for logical tenant isolation using encrypted schema partitioning and row-level security within PostgreSQL. This achieved enterprise-grade HIPAA compliance and zero-trust data separation while maintaining a single, easily deployable database pipeline.
Asynchronous webhook ingestion for lab event streams
High-volume enterprise testing spikes can overwhelm API infrastructure when lab batch results are released simultaneously. We built event-driven SQS queues and AWS Lambda workers to handle incoming lab webhooks asynchronously, buffering traffic spikes and ensuring zero dropped results during peak reporting windows.
Results
With Elementica's enterprise multi-tenant layer, LetsGetChecked swiftly launched its corporate testing program, processing over 100,000 workforce tests across major enterprises. The platform enabled corporate leaders to replace manual spreadsheets with real-time, automated safety intelligence, supporting safe workplace re-openings during peak pandemic uncertainty.
Product evolution
Following the enterprise deployment, LetsGetChecked leveraged this multi-tenant architecture to expand its B2B offering beyond pandemic mitigation. The corporate platform now powers routine employee biometric screening, chronic disease monitoring, and enterprise wellness programs across thousands of organizations nationwide.
