Case Study

Scalable Healthcare Platforms for Primary Care

Sep 2014 to Oct 2020

Architected enterprise-grade healthcare solutions including cloud-based EMR/EHR platforms for primary healthcare government initiatives. Naresh Koutam, now Passer's CTO, led the solution architecture, designing for scale, compliance, and high-availability across private and public cloud deployments. Built the engineering team, processes, and tooling from scratch.

The challenge

Healthcare-grade platforms across diverse deployments.

TCS Healthcare Platform & Products needed solutions deployable across private and public clouds for diverse customer requirements while meeting compliance, high availability, and disaster recovery standards for sensitive healthcare data. The team also needed to be built from scratch with standardized engineering processes and modern digital capabilities like speech-to-text integration to keep pace with evolving clinical workflows.

The solution

Architecture, migration, modernization, and team build.

01Solution architecture for cloud-based EMR/EHR platforms
02Speech-to-text integration via Google Cloud for physician documentation efficiency
03Migration strategy from private cloud to public cloud with compliance preservation
04Engineering processes, practices, and tooling for consistent compliant delivery
05Prototyping of new healthcare technologies and tool evaluation
06Standing up a cross-functional product engineering team (full-stack, data, DevOps, QA)
07Mentoring and technical management across the engineering organization
Scope

Scale, compliance, and team build.

Architecture

Designed and implemented enterprise-grade features for healthcare platforms. Compliance, high availability, and disaster recovery were first-class architectural concerns rather than afterthoughts.

Outcomes

What it added up to.

6+ yrs

Multi-cloud
private to public migration
EMR/EHR
compliance-grade design
Cross-functional
team scaling and standards

Deep domain knowledge that informs every Passer engagement.

The TCS Healthcare years built the foundation of the architectural rigour Passer applies to regulated industries today: cloud strategy, compliance-aware design, team scaling, and the muscle memory required to deliver enterprise software in environments where mistakes have human consequences.

Platform connection

Influences the Passer software stack.

The architectural patterns, engineering process discipline, and team-build approach pioneered through TCS Healthcare are directly visible in how Passer designs Nemo, Catalyst, and the rest of the product portfolio today.
