Healthcare AI/ML Software Architect | Polyglot (Java, Go, Python, Rust) | AI/ML | AWS Solutions Architect Professional | HIPAA/DPDP Compliance | 25+ Yrs Enterprise Systems
I architect and build production-grade healthcare platforms that serve real patients in real clinics — not just POCs that sit on slides.
As CTO & Co-Founder of RatnaGlobalTech, I lead 100+ engineers building AI-powered healthcare ecosystems across India. Our work was shortlisted for the AI by HER Global Impact Challenge for delivering healthcare technology to rural and underserved communities.
POLYGLOT ARCHITECTURE
I believe in choosing the right language for the right problem:
→ Java & Spring Boot — My primary stack for enterprise healthcare platforms. 20+ years building microservices handling patient data, billing, and compliance across multiple jurisdictions.
→ Go — High-throughput API gateways, real-time data ingestion, and lightweight services where concurrency and performance matter.
→ Python — AI/ML pipelines, NLP models for multilingual healthcare support, predictive analytics, and LLM integration (LangChain, TensorFlow, PyTorch).
→ Rust — Cryptographic operations, secure data processing, and systems-level components where memory safety protects sensitive patient data.
AI & MACHINE LEARNING
I build AI systems that work in production, not just notebooks. Clinical NLP for multilingual symptom analysis, predictive patient risk scoring, appointment optimization, RAG pipelines with Gemini/GPT, and AI-powered diagnostics — all with proper model versioning, drift detection, and human-in-the-loop validation.
DATA ARCHITECTURE
End-to-end data strategy from legacy modernization to cloud-native lakehouses. I specialize in SSIS-to-Databricks migration, medallion architecture (Bronze/Silver/Gold), Apache Spark, Delta Lake, Kafka-based CDC pipelines, and ML feature stores. I turn raw operational data into governed, queryable, trustworthy assets.
CLOUD & SECURITY
AWS Solutions Architect Professional certified. I design multi-account strategies, hybrid cloud deployments, and cost-optimized infrastructure. Security-first approach with OAuth2/JWT, MFA, HashiCorp Vault, encryption at rest and in transit, and comprehensive audit trails.
WHAT I DELIVER
→ Healthcare platform architecture (EHR, telemedicine, pharmacy, billing workflows)
→ Microservices design and implementation with production-hardened patterns
→ Legacy monolith to microservices migration
→ AI/ML pipeline development and integration
→ Data engineering and lakehouse architecture
→ Architecture reviews, code audits, and technical due diligence
→ Fractional CTO / Technical leadership
CMM Level 5 certified organization.
Work Terms
AVAILABILITY & TIME ZONE OVERLAP
Based in Hyderabad, India (IST, UTC+5:30). I structure my schedule to maximize overlap with US clients:
→ EST/CST clients: 6 hours of daily overlap (typically 8:00 AM – 2:00 PM your time)

COMMUNICATION
I believe in proactive, structured communication — not just responding when asked.
→ Daily async updates via Slack, Teams, or email
→ Weekly video sync calls (Zoom/Google Meet/Teams)
→ Shared task boards (Jira, Linear, Trello — your preference)
→ All documentation in Confluence, Notion, or your preferred wiki
Response time: Within 2 hours during overlap hours, within 12 hours outside overlap.
ENGAGEMENT MODELS
→ Hourly consulting: Architecture reviews, code audits, technical advisory
→ Project-based: Fixed scope with milestone-based deliverables and payments
→ Retainer: Ongoing fractional CTO / lead architect (minimum 20 hrs/week)
→ Team augmentation: I can bring in vetted engineers from my team for larger initiatives
PAYMENT
Preferred: Milestone-based payments for projects, weekly/biweekly for hourly/retainer engagements. Open to escrow-based payments through the platform.
WHAT I NEED FROM YOU
→ Clear project brief or problem statement
→ Access to relevant repos, docs, and environments
→ A designated point of contact for decisions
→ Reasonable response times on blockers
