I developed backend solutions for the buy-now-pay-later platform supporting €40 billion in European BNPL operations. I built a Spring Batch processing system using Java, Spring Batch, JUnit, and Mockito to sync millions of transaction records across multiple downstream APIs to BigQuery, delivering $75,000 in monthly cost savings and resolving critical data inconsistencies. Additionally, I developed a comprehensive testing framework for functional validation of all batch job components.

• Automated data center management for Pure Private Cloud by developing custom Nautobot plugin using Django and NAPALM. Worked directly with director-level leadership to improve switch configuration accuracy from 60% to 99% and reduce manual effort by 90% across all data center network switches.

• Demonstrated strong leadership by mentoring interns, conducting knowledge transfer sessions, leading code reviews, and actively participating in sprint planning processes. Presented solutions to executive leadership including CTO, showcasing strong communication abilities and technical expertise. Consistently applied Agile methodologies to improve team productivity and project outcomes.

• Spearheaded end-to-end SDLC implementation of Auto Sim Rehab service, taking full ownership from requirements gathering through maintenance. Architected microservices-based distributed system using Flask, RabbitMQ, Redis, PostgreSQL, Temporal Cloud and Nomad. Reduced simulator rehabilitation time from 5 hours to 10 minutes, significantly increasing productivity across 2,000+ test environments while handling 200+ daily operations with ≥95% reliability. This flagship project directly contributed to promotion to MTS3.

• Architected comprehensive CI/CD pipeline for automating deployment of machine images across all infrastructure components (like simulators, initiators, launchpads, dev-VMs). Implemented workflow that triggered when developers pushed changes to image source code in Imaginator (open-source tool), automatically executed sanity and unit tests on staging machines, and deployed to production upon validation. Integrated multiple internal tools including Jenkins, GitHub ecosystem, and Imaginator/Dominator frameworks.

• Led migration of FlashBlade simulator testbed from Ubuntu 14 to Ubuntu 22, collaborating extensively with simulator development team. Utilized OpenStack, Packer templates, and Ansible playbooks to create golden images and implemented batch-wise deployment automation. Reduced deployment time by 90% through Jenkins-based parallel deployment pipelines and maintained golden image throughout term, addressing bugs and ensuring updates were promptly applied.

• Developed CLI2API tool mapping commands to REST APIs, improving testing efficiency

• Contributed to Python test framework migration from Perl with enhanced parallel execution

• Created regression analysis tool reducing debugging time by 90%

• Built Perl-to-Python transpiler for test script conversion

• Implemented regression testing using Python, Perl, Flask, Git, Jenkins

• Gained expertise in networking protocols (SDN, VRRP, OSPF, BGP, VLAN)
