About

Backend Software Engineer with 3.5 years at Tekion Corp, designing and owning production Java and Spring Boot microservices for a cloud-native automotive retail platform used every day by dealerships. WHAT I DO I own services end to end - HLD/LLD, implementation, release and production on-call. My work centres on clean API design, event-driven integration, performance optimization and system reliability at enterprise scale. SELECTED IMPACT - Architected the Repair Order (RO) Validation microservice as the single validation authority for RO workflows, centralizing logic that previously spanned multiple enterprise workflows into an independently deployable service. - Designed a config-driven rule engine that externalized 50+ business rules, eliminated 40% of hard-coded validation logic and enabled real-time rule updates with zero service redeployment. - Cut API response latency 20% on the platform's highest-traffic endpoints using asynchronous processing with CompletableFuture and slow SQL query optimization. - Migrated 60+ REST APIs to versioned contracts with full backward compatibility, so consumers upgrade without breaking changes. - Delivered 15+ cross-functional requirements with Product and QA and reduced post-release defects 12%. - Raised automated test coverage from 65% to 90% with 100+ JUnit and Mockito tests, cutting production regressions 20%. TECHNICAL SKILLS Languages: Java, SQL, JavaScript, C++ Backend: Spring Boot, Spring MVC, Spring Data JPA, Hibernate, RESTful APIs, Microservices, Asynchronous Processing (CompletableFuture) Data & Messaging: Apache Kafka, Redis, MySQL, MongoDB, Elasticsearch, SQL query optimization Cloud & DevOps: AWS, GCP, Kubernetes, Docker, CI/CD pipelines Practices: Service design (HLD/LLD), API versioning and backward compatibility, event-driven integration, OpenAPI/Swagger, unit and integration testing, code review, on-call and incident response AI ENGINEERING OpenAI API (GPT-4o), function calling and LLM tool use, LLM integration, prompt engineering. Built an end-to-end real-time AI voice agent (Twilio Media Streams, Deepgram STT, GPT-4o, ElevenLabs TTS) that books car service appointments through natural phone conversations. EDUCATION B.Tech, Computer Science and Engineering - NIT Jamshedpur (CGPA 8.0/10) Open to backend, distributed systems and platform engineering roles. Happy to connect.

Software Engineer 1 at Tekion Corp, Apr 2025 - Present · 1 yr 6 mos, Backend engineer on Tekion's cloud-native automotive retail platform, designing and owning production Java and Spring Boot microservices that power enterprise dealership workflows. Promoted from Associate Software Engineer. - Architected the Repair Order (RO) Validation microservice in Java and Spring Boot as the single validation authority for RO workflows, centralizing complex business validations that previously spanned multiple enterprise workflows, by owning HLD and LLD and extracting duplicated validation logic into an independently deployable service. - Eliminated 40% of hard-coded validation logic and enabled real-time rule updates with zero service redeployment, externalizing 50+ business rules into configuration, by designing a config-driven rule engine that resolves rules at runtime rather than at compile time. - Delivered 15+ cross-functional business requirements and reduced post-release defects 12%, by partnering with Product and QA across requirement definition, implementation and pre-release validation. - Own service design (HLD/LLD), API versioning and backward compatibility, event-driven integration over Apache Kafka, and production on-call. Tech: Java, Spring Boot, Spring MVC, Spring Data JPA, Hibernate, Microservices, REST APIs, Apache Kafka, Redis, MySQL, MongoDB, Elasticsearch, AWS, GCP, Kubernetes, Docker, CI/CD, OpenAI API (GPT-4o), LLM function calling

Associate Software Engineer at Tekion Corp, Jul 2023 - Apr 2025 · 1 yr 10 mos, Built and operated Java and Spring Boot microservices on Tekion's cloud automotive retail platform, focused on API performance, contract stability and production reliability. - Cut API response latency 20% on the platform's highest-traffic endpoints, by introducing asynchronous processing with CompletableFuture and optimizing slow SQL queries. - Migrated 60+ REST APIs to versioned contracts with full backward compatibility across Spring Boot microservices, supporting migration between API versions without breaking existing consumers, by enforcing compatible contract evolution on every change. - Owned business-critical production microservices end-to-end on an on-call rotation, sustaining production reliability through root cause analysis, code review and production incident resolution. Tech: Java, Spring Boot, Spring MVC, Spring Data JPA, Hibernate, REST APIs, Microservices, CompletableFuture, Apache Kafka, Redis, MySQL, MongoDB, Elasticsearch, SQL query optimization, AWS, Kubernetes, Docker, CI/CD

Engineering Intern at Tekion Corp, Jan 2023 - Jun 2023 · 6 mos, Backend internship on Tekion's automotive retail platform, focused on test automation, observability and API standardization across Spring Boot microservices. - Raised automated test coverage 65% to 90% and cut production regressions 20%, by authoring 100+ unit and integration tests in JUnit and Mockito, wired into the build pipeline. - Improved reliability and observability across Spring Boot microservices, by adding centralized logging, standardized exception handling, and event-driven inter-service communication over Apache Kafka. - Standardized API contracts for 20+ microservices, adopted as the integration reference by frontend and QA teams, by authoring OpenAPI/Swagger documentation. Tech: Java, Spring Boot, REST APIs, Microservices, JUnit, Mockito, OpenAPI/Swagger, Apache Kafka, MySQL, MongoDB, Git
