→ Databases: PostgreSQL, MongoDB, Redis
→ Cloud & DevOps: AWS, Docker, Kubernetes, CI/CD
→ Healthcare & Compliance: HL7, FHIR, HIPAA-aware architectures, Audit Logging
What Makes Me Different:
- 265+ successful projects delivered
- $300K+ earned on Upwork
- 20,000+ working hours (long-term client trust)
- Clean, scalable, production-ready code
- Clear communication & fast response
