I'm a Senior Full Stack Engineer with 11+ years building scalable, secure web applications for US companies (Gluu, IQVIA). I specialize in React, TypeScript, Java, Spring Boot, and Identity & Access Management (OAuth 2.0, SAML, OIDC).
WHAT I DO BEST:
- Full-Stack Development: Build modern React frontends with TypeScript and robust Java/Spring Boot backends
- Identity & Access Management: OAuth 2.0, SAML, OIDC, SSO implementations that secure your users
- Microservices Architecture: Design and deploy scalable microservices with Spring Boot
- API Development: RESTful APIs that handle millions of requests with sub-100ms response times
- Healthcare Tech: FHIR/HL7 integration, EMR/EHR systems, HIPAA-compliant solutions
- Performance Optimization: Reduce load times by 40%+, improve database query performance by 30%+
PROVEN TRACK RECORD:
✓ Built identity orchestration platform serving 10k+ developers (Agama Lab - Linux Foundation)
✓ Reduced deployment time by 40% through Jenkins CI/CD pipeline implementation
✓ Achieved 80% test coverage across microservices using JUnit, Mockito, integration tests
✓ Processed 500K+ patient records daily with 99.9% uptime in healthcare systems
✓ Improved API performance by 30% through caching, query optimization, load balancing
✓ Integrated MFA systems (Twilio, DUO, Okta) supporting 100K+ daily authentications
TECH STACK:
Frontend: React, TypeScript, Next.js, Redux, Vite, JavaScript, Material-UI, Chakra UI
Backend: Java, Spring Boot, Spring Security, Quarkus, Jakarta EE, Microservices
Database: PostgreSQL, MySQL, MongoDB, Redis, DynamoDB
Cloud & DevOps: AWS (EC2, S3, RDS, Lambda), Docker, Kubernetes, Jenkins, CI/CD
Security: OAuth 2.0, SAML, OIDC, RBAC/ABAC, OWASP Top 10, JWT, Cedar
Testing: JUnit, Mockito, Selenium, Integration Testing, TDD
AI: LLM, RAG, Pinecone, Claude Code, Cursor, etc
