Varun Krishna

I’m a back-end software engineer focused on building scalable, high-performance applications with strong problem-solving and continuous technical growth. I target Back-end Engineering opportunities, preferably in Bengaluru, Kochi & Chennai, where I can help deliver production-grade services.

At o9 Solutions, I engineered and supported Python-driven back-end services and RESTful APIs for an enterprise supply chain planning platform, with 90% automated test coverage. I orchestrated the full back-end development lifecycle—architecture design, coding, validation, deployment, and maintenance—and delivered tailored solutions that reduced implementation timelines by 40%.

I also architected reusable back-end modules and platform-level enhancements that simplified configuration and deployment workflows, cutting repetitive implementation effort by 80%. I prioritize clean architecture, modular design, robust authentication, and secure application development practices.

From my internships and projects, I’ve developed strong end-to-end implementation habits—interpreting requirements into actionable technical strategies, improving release efficiency, and building reliable workflow and API systems. For example, I designed a scalable multi-tenant back-end using FastAPI and PostgreSQL with schema validation via Pydantic, including JWT-based authentication and role-based access control.
