Where I’ve
shipped things.

Jul 2024 — Present
Atlas Primary
Current
Software Engineer
  • Resolved OS-level OutOfMemoryErrors on panel exports by architecting a generic batch processor with configurable chunking and streaming DB reads — eliminated system crashes.
  • Achieved 100× latency reduction on project listing API (60s → 600ms) via shared query composition and bulk-fetch patterns.
  • Migrated scheduled jobs to Quartz with Liquibase; exposed inspect/reschedule/pause lifecycle APIs with environment guards.
  • Strengthened financial and CSAT audit accuracy using JaVers (timestamp normalisation, bulk query optimisation).
  • Replaced ad hoc env checks with a central profile model — eliminated cross-environment bleed across integrations and background tasks.
  • Built Vue 2/3 SPAs for quote workflows, invoicing settings, and email-safe panelist templates.
  • Contributed Kotlin/Spring microservices for quoting and notifications; hardened email and logging config.

Software Engineer Intern
  • Secured Spring Boot microservices with JWT authentication for REST API endpoints.
  • Automated UI/UX testing with Selenium Grid; contributed to CI/CD pipelines via Bitbucket and Jira.
Aug 2022 — Jan 2023
Fresh Express India
Internship · Pune
Software Developer Intern
  • Built IoT device management system (Django, Python) with real-time monitoring and OTA firmware updates across distributed devices.
  • Developed secure REST APIs for device-to-cloud data flow enabling seamless frontend integration.
