   Breaking an Ansible automation orchestration platform serving 25,000 executions a day out of its monolith and into event-driven processors, without ever taking it down.

   • Worked on the re-architecture of a large Activiti BPMN and polling-based monolith serving 25,000 executions a day into segregated event-driven processors backed by custom self-healing active-active Hazelcast queues, cutting platform-level execution overhead by over 60% and code smell by 70%.
   • Designed and built a parking-lot system that migrated every in-flight execution onto the new architecture with full state reconstruction, making the event-driven cutover a zero-downtime deployment.
   • Designed and implemented a token-bucket rate limiter scoped at user and global level, enforced by annotation and overridable via API, closing off denial-of-service by internal callers while still allowing elevated access where it was warranted.
   • Replaced a misfire-prone custom Quartz setup with a cross-region dual-DC job scheduler, taking misfires to zero and tightening trigger lag from ±20s to ±5s.
   • Found non-compliant handling of the change life-cycle in the application and drove the fix with the ITSM team, documenting and remediating the flow before it became a penalty.
   • Built an AWX simulator with DSL-driven scenario routing across database operations, delays and API responses, making regression and performance testing possible at 50 executions per minute without loading production Ansible.
   • Layered a tool-calling LLM agent over the simulator with custom native tools, so engineers can author simulations in plain language, taking authoring time from 30 minutes to under 5.

2. Software Engineer · Societe Generale Global Solution Centre

   Feb 2024 - Oct 2025

   Whitefield, BangaloreFull-time

   Platform and backend work across a large regulated estate: cloud migration, CI/CD, and the database jobs underneath it.

   • Architected multiple on-premise applications onto Azure (AKS, Azure PostgreSQL, DNS, certificates and Key Vault) and automated the provisioning, cutting deployment effort by 80%.
   • Automated the blue-green AKS migration end to end, covering resource migration, network redirection and access re-provisioning, cutting per-cluster cutover from 4 hours to 1.
   • Led the migration of every Docker image from Mirantis Secure Registry to Harbor, writing the Jenkins pipelines and Dockerfiles for the new workflow.
   • Owned the team's other structural migrations end to end: Nexus to JFrog for artifacts, and Jenkins to GitHub Actions for CI.
   • Optimized C-shell and pl/pgsql database scripts by parallelizing independent business logic, taking a nightly job from 5.5 hours to 3.
   • Migrated Excel-based VBA solutions to Python cloud functions, removing platform dependency entirely and backing them with tests at 70% coverage.
   • Built features across Java/Spring Boot services with React and Angular front-ends in an agile team, and added API-based data fetching for compliance by decomposing complex SQL queries while holding response-time overhead under 5%.
