Projects

GabiLabs

March 1, 2025 – Present

• Developed core recruitment workflows using Java Spring Boot microservices — candidate management, job matching, resume scoring, and automated notification pipelines. • Built a secure multi-tenant authentication layer using Spring Security, JWT, and OAuth 2.0 — with role-based access for employers, recruiters, and candidates. • Designed asynchronous resume scoring and notification services using event-driven architecture, improving processing throughput and decoupling service dependencies. • Integrated third-party APIs using Spring's RestTemplate / WebClient with structured retry logic, timeout handling, and centralized error management. • Leveraged AWS Lambda for lightweight background jobs and AWS Cognito for identity management; used S3 for frontend asset hosting

Zilliant CPQ

August 1, 2023 – February 1, 2025

• Built Java Spring Boot microservices powering an enterprise CPQ system — covering pricing rules, real-time quote generation, and contract lifecycle management. • Designed a configurable rule-based pricing engine in Java (Strategy + Chain-of-Responsibility patterns) — evaluating complex, multi-condition pricing logic dynamically at runtime. • Implemented clean REST API architecture with Spring MVC and Hibernate-optimized data access layer for high-throughput pricing requests. • Deployed services on AWS EC2 and Elastic Beanstalk; used CloudWatch for centralized logging and proactive alerting across the CPQ service layer.

NirvanaFusion

December 1, 2019 – July 1, 2023

• Contributed to building and scaling a Spring Boot microservices system — improving modularity, independent deployability, and release velocity. • Designed backend services for order management, inventory tracking, and payment processing using Spring Boot, JPA/Hibernate, and MySQL. • Integrated Braintree and Datacap payment gateways via clean Java service layers with full transaction error handling, rollback support, and audit logging.
