Backend engineer specializing in Java/Go microservices, cloud orchestration, and CI/CD reliability.
IndiaWhat I'm looking for
I’m a backend engineer who builds high-concurrency services and reliable delivery pipelines across Java and Go. I focus on performance, security hardening, and operational stability—so teams ship faster with less risk.
At CLOUDBEES, I’ve led large-scale platform improvements, including migrating core backend services from Jetty 11.0.19 to 12.0.23 and aligning with Jakarta EE 10 (Servlet 6.0). I also architected a Go-based high-concurrency log intelligence microservice that streams GKE agent logs to Gemini 1.5 Flash and enables real-time RCA for failed CI/CD pipelines to reduce developer MTTR.
I modernized complex hospitality workflows at AGILYSYS by moving high-throughput guest stay operations to event-driven architecture using a hybrid stack of Angular, Java Spring Boot, and Go. I built integration services with Go and RabbitMQ to decouple latency-sensitive third-party APIs, and delivered low-latency device integrations via Azure Function Apps and Event Grid.
Earlier, I worked as a System Engineer and Project Engineer, contributing to fund summarization logic, implementing Spring Batch with 99.9% accuracy for General Ledger processing, and handling backend transformations for proof data generation. I bring strong engineering discipline—debugging, refactoring, and delivering features with measurable correctness and reliability.
Experience
Work history, roles, and key accomplishments
Hardened the Groovy DSL execution environment using field/keyword whitelisting to mitigate arbitrary code execution and sandbox escapes for user-defined scripts. Migrated the backend from Jetty 11 to Jetty 12 (Jakarta EE 10) and optimized GKE scaling orchestration, reducing agent startup latency by 40% while building a Go-based high-concurrency log intelligence service.
Built serverless Azure integration workflows to connect the hospitality stay platform with physical hardware devices using Azure Function Apps and Event Grid, including Go-based low-latency device handlers. Modernized guest stay services by moving check-in operations to an event-driven architecture (Angular, Spring Boot, Go) and engineered Go/RabbitMQ integration microservices to decouple latency-
Contributed to a fund summarization module processing $2B+ transactions monthly through core business logic, bug fixing, refactoring, and delivery of small stories and features. Implemented a Spring Batch solution for General Ledger processing, achieving 99.9% accuracy, and developed backend transformations to generate precise proof data for institutional clients.
Supported testing and project coordination activities, contributing to quality assurance, team communication, and overall project management. Gained experience in management and testing during a period when internal development opportunities were limited.
