Hi, I’m Arun Sagar S A, a backend software engineer based in Ottawa with a focus on Java/Spring Boot APIs, integrating external services, and shipping production-grade software in enterprise SaaS environments. I’m comfortable navigating messy codebases and legacy systems, and I enjoy turning complex requirements into robust, scalable backend services. I’m actively building AI-enhanced applications end-to-end, from FastAPI backends and Whisper/LLM pipelines to Terraform-managed cloud infrastructure. I use Claude/Claude Code as part of my development workflow for codebase exploration, debugging, refactor planning, and documentation, while validating outputs through tests and peer reviews. I’m looking to apply these skills in a Junior AI Software Engineer role focused on practical AI integration, collaborating with cross-functional teams to deliver reliable AI-powered features.…Hi, I’m Arun Sagar S A, a backend software engineer based in Ottawa with a focus on Java/Spring Boot APIs, integrating external services, and shipping production-grade software in enterprise SaaS environments.

Java Developer at Agility PR Solutions

May 1, 2025 - Present

Built and shipped REST API features across folder and mention service layers including CRUD, soft-delete, transactional rollback behavior, and API versioning updates. Designed and implemented undo-capable delete flows; when a user removes a mention from a folder, the backend soft-deletes the record and keeps it recoverable for an undo-banner pattern coordinated with the frontend. Extended bulk operations enabling mass updates, streaming exports, and imports to scale across thousands of customer accounts. Worked across a multi-module Maven monorepo with concurrent contributors and production-safe release processes. Designed and built a zero-downtime Jenkins deployment pipeline that validates Maven artifacts, deploys JARs, updates traffic load balancers, restarts services, and performs health checks to prevent unhealthy nodes from rejoining traffic. Used Claude/Claude Code daily for codebase navigation, debugging hypotheses, planning refactors, drafting test plans, and documenting change
