Skilled in modernization initiatives, security vulnerability remediation, CI/CD automation, and driving engineering best practices within Agile teams.

Technology Lead — The Vanguard Group (Client) at Infosys Ltd. (2023-07 – Present)

• Spearheaded security vulnerability remediation across a portfolio of 10+ microservices, REST APIs, and batch applications — reducing critical security risk exposure by prioritizing, analysing, and deploying fixes in coordination with security and infrastructure teams.
• Led the end-to-end migration of core microservices from Spring 5 to Spring 6 and Java 11 to Java 17, ensuring zero-downtime deployments and backward compatibility across all dependent downstream systems.
• Architected and executed upgrade strategy for critical middleware components (Gatekeeper, TEB bundle, DB2, Oracle), improving throughput and compatibility of RESTful services and batch processing pipelines.
• Owned application observability by designing and maintaining Splunk dashboards and Honeycomb tracing configurations, enabling rapid root-cause analysis and reducing mean time to resolution (MTTR) by 40%.
• Designed JMeter performance test plans and executed load testing via PTaaS platform, identifying and resolving performance bottlenecks for high-traffic microservices before production releases.
• Developed and maintained Splunk reporting queries to continuously monitor API traffic volume, response time SLAs, and error rates, providing data-driven insights to stakeholders.
• Automated infrastructure operations (cell enablement, shutdown, restart) by creating and executing LNL runbooks in ServiceNow integrated with Grafana, reducing manual operational overhead for the team.
• Managed and streamlined deployment pipelines leveraging Ansible playbooks and AWS services, enabling consistent and repeatable deployments across development, staging, and production environments.
• Conducted comprehensive unit, integration, regression, and performance testing cycles for migrated services, ensuring 100% functional coverage and adherence to SLA benchmarks before go-live.

Technology Analyst — American Express (Client) at Infosys Ltd. (2023-01 – 2023-06)

• Collaborated with cross-functional stakeholders to gather, analyse, and translate complex business requirements into technical specifications and data schemas using the Amex One-Data Framework.
• Developed and validated functional schemas ensuring data consistency, integrity, and compliance with enterprise data governance standards across multiple application tiers.
• Managed multi-environment deployments (E1, E2, E3) through the eCP platform, ensuring reliable release cycles and minimizing environment-specific defects during testing phases.

Technology Analyst — Charles Schwab (Client) at Infosys Ltd. (2022-01 – 2022-12)

• Designed and developed event-driven microservices using Spring Batch and Spring Cloud Data Flow (SCDF), improving batch processing efficiency and reducing job completion time by 30%.
• Led the conversion of legacy Oracle stored procedures into modular, maintainable Java REST APIs, modernizing the data access layer and decoupling business logic from the database tier.
• Deployed and managed microservices on Pivotal Cloud Foundry (PCF), configuring scaling policies and health monitoring to ensure high availability in the production environment.
• Integrated SCDF task orchestration with Control-M enterprise job scheduling, enabling automated, dependency-aware batch job execution across the production landscape.

Java Developer at P2P System Pvt. Ltd. (2018-09 – 2022-01)

• Designed, developed, and maintained enterprise Java applications using Spring MVC, Spring Core, and Hibernate ORM, delivering full-cycle features and REST API integrations across business domains.
• Performed root-cause analysis on production defects in monolithic Java applications and implemented preventive fixes, improving application stability and reducing recurring issues.
• Participated in Agile ceremonies and built strong fundamentals in Java, SQL optimisation, and application debugging — forming the technical base for subsequent lead-level roles.
