Backend Engineering & Microservices
6 years of experience building high-throughput, fault-tolerant microservices at telecom scale (AT&T, T-Mobile, PLDT: 50K+ requests/min, 1M+ users). Expertise in Java 8/17/21, Spring Boot 3.5, Spring Integration, Spring Security, Spring Cloud, Hibernate/JPA, REST, WebSockets, and Microservices architecture.
AI Integration & LLM Engineering
Hands-on experience integrating AI into production backends using Spring AI (ChatClient, Advisors, RAG), MCP (Model Context Protocol), Agentic AI (Claude Agent SDK, LangChain, LangGraph), PGVector, Claude API, AWS Bedrock, Ollama, OpenAI, and Prompt Engineering. Builder of AgentBridge, a governed MCP gateway for existing Spring services.
Cloud & DevOps
Proficiency in AWS (EC2, Lambda, EKS, S3, Bedrock), GCP, Azure, Docker, Kubernetes, Jenkins, GitLab CI/CD, GitHub Actions, and Terraform. Delivered zero-downtime CI/CD deployments and containerized legacy applications, reducing server costs INR 3.8L/year.
Distributed Systems & Architecture
Deep knowledge of System Design, Distributed Systems, Event-Driven Architecture, DDD, Fault Tolerance, Resilience4j, Rate Limiting, Idempotency, and Enterprise Integration Patterns (EIP).
Data & Messaging
Experience with PostgreSQL, MySQL, MongoDB, Redis, Ehcache, and Apache Kafka for building scalable data pipelines and messaging-driven integrations.
Observability & Testing
Skilled in OpenTelemetry, Micrometer, Prometheus, Grafana, JUnit 5, Mockito, Testcontainers, and Swagger/OpenAPI for production-grade observability and testing.
AI-Native Development Tools
Regular use of Claude Code, Claude Cowork, GitHub Copilot, and Cursor for AI-assisted development, generation, and refactoring workflows.
Payment & Integration Systems
Engineering of idempotent REST APIs with retry logic and circuit breakers, handling 5,000+ transactions per second for prepaid service processing and geolocation-aware credit-card surcharge flows.
Remote Collaboration
Strong async written communication, architecture decision records, documentation-first workflows, and proven US-timezone overlap of 4.5+ hours daily.
