// Work Experience
Software Engineer with 3+ years building distributed systems and cloud-native solutions
Cisco | Software Engineer
Sep 2024 – Present · San Jose, CA- Engineered high-throughput distributed data pipelines using Java, AWS EMR, and Apache Spark to process 1.2TB of daily network telemetry, enabling real-time threat detection via streaming aggregations, window functions, and anomaly scoring at massive scale.
- Designed agentic AI workflows using Python and LLMs to automate end-to-end security alert correlation, reducing false-positive triage time by 15% through intelligent alert grouping, contextual RAG-based retrieval, and automated root cause analysis on live event streams.
- Architected serverless microservices using AWS Lambda, SQS, and Fargate with Spring Boot REST APIs, automating vendor onboarding and security auditing pipelines — cutting manual processing overhead by 25% while enforcing schema validation and full audit logging.
- Led system design, performance optimization, and rigorous code reviews for scalable Java and Python backend services, enforcing SOLID principles and distributed tracing via DynaTrace and Splunk to maintain 99.9% SLA across all mission-critical security applications.
- Conducted resilience testing including chaos engineering, load testing, and vulnerability assessments on core security libraries, identifying and remediating critical failure points to ensure fault tolerance and zero data loss across distributed cloud environments.
- Owned full CI/CD lifecycle using Jenkins, GitHub Actions, Docker, Kubernetes, and Helm, implementing blue-green deployments and automated regression gates that accelerated release velocity by 3x with zero unplanned production outages.
Humana (Tata Consultancy Services) | Associate Software Engineer
Aug 2021 – Aug 2022 · Hyderabad, India- Developed Java Spring Boot microservices on SAP BTP for healthcare member enrollment and claims management, processing 15,000+ clinical records per cycle with 99.95% uptime via circuit breakers, retry logic, and thread-safe concurrency patterns.
- Designed RESTful APIs with OAuth2 and JWT authentication and RBAC authorization, integrating PostgreSQL and MongoDB to support flexible multi-tenant healthcare data models with consistent sub-300ms p95 query latency under load.
- Optimized complex SQL queries with composite indexing, query plan analysis, and Redis caching layers, reducing retrieval latency by 40% and cutting peak read load on primary PostgreSQL instances by 35% under sustained high-concurrency production traffic.
- Implemented Kafka event-driven messaging for real-time claims status updates across downstream microservices, applying idempotency keys and DLQ patterns to guarantee exactly-once delivery and fault-tolerant async processing under peak load.
- Built JUnit and Mockito test suites achieving 85%+ code coverage with TDD principles, and automated Jenkins CI/CD pipelines via Git and Docker — reducing overall release cycle time by 30%.
- Enforced HIPAA compliance with field-level PII encryption, structured JSON audit logging, and role-based data masking across all REST endpoints, backend services, and NoSQL data stores.
