About

I build backend systems that hold up under real load — not just demo traffic.

Java Backend Engineer with 3+ years delivering production Spring Boot microservices and REST APIs at scale. At Cornerstone OnDemand (NASDAQ-listed, 75M+ platform users), I built APIs for an enterprise LXP and took full architectural ownership of an internal engineering framework at one year of experience. At RAK Softech, I was sole backend engineer across two commercial B2B SaaS products — from API design to AWS production deployment.

I improved average API response time by ~40% via MySQL indexing and Redis caching, cut release cycles via Docker and Jenkins CI/CD, and led a localisation framework migration that reduced bugs by ~30%. I also hold an MCA with specialisation in AI & Data Science — giving me the background to work on AI-adjacent backend systems as well as core Java engineering.

Currently on a career break, working on backend development for Punekar — a Pune community app, live on iOS and Android. Immediate joiner, open to on-site and hybrid Java Backend Engineer roles.

JavaSpring BootSpring SecurityMySQLRedisElasticsearchReactDockerJenkinsAWS EC2/S3

Sole backend engineer across two commercial B2B SaaS products — Employee Management System and B2B Commerce Platform — from architecture through AWS production deployment.

  • Architected and built 8+ Spring Boot microservices for user management, RBAC, and workflow automation — each independently deployable, secured with JWT auth and Spring Security RBAC.
  • Integrated Elasticsearch for full-text search across workflow records, enabling fast retrieval with sub-second response times on large datasets.
  • Improved average query response time by ~40% via targeted MySQL schema indexing and Redis caching on high-traffic reporting and transactional endpoints.
  • Containerised services with Docker and set up Jenkins CI/CD pipelines, reducing release cycle time and eliminating manual deployment steps; integrated 3+ third-party APIs with structured error handling and retry logic.
  • Built and maintained React UI components for admin and user-facing dashboards, managing state and connecting to Spring Boot REST endpoints.
