Insuredmine LLCAPR 2022 -- PRESENT
SR. SOFTWARE ENGINEER · BENGALURU
  • Leading architecture and development of a real-time reporting system using ClickHouse as the analytical data store and Spring Boot (Java) -- enabling generation of complex, multi-million-row insurance reports with sub-second query response at peak load.
  • Designed columnar data ingestion pipelines feeding ClickHouse from transactional MySQL sources, implementing materialized views and projection strategies to optimise analytical query patterns.
  • Architected and led full monolith-to-microservices migration using Spring Boot 3 and Node.js -- improving fault isolation and deployment velocity across the platform.
  • Implemented Redis caching layer for high-volume external API search queries -- achieved 400% reduction in average response time.
  • Built secure data onboarding pipelines supporting CSV, Excel, JSON, and XML with configurable field mapping and validation.
  • Integrated 10+ third-party carrier APIs via REST and SOAP (JAX-WS, MyBatis), bridging modern services with legacy EDI-based systems.
  • Defined service contracts via OpenAPI 3; introduced structured logging and distributed tracing via ELK and OpenTelemetry across the microservices mesh.

FULL STACK ENGINEER · MUMBAI
  • Led backend engineering for an award-winning Rx medicine delivery app -- Lyft and Uber API integration with end-to-end prescription verification and HIPAA-aligned data handling.
  • Established Jenkins CI/CD pipelines with automated test gates, cutting release cycle from multi-day manual deploys to sub-hour automated delivery.
  • Contributed to Node.js API design and Angular frontend modules across the delivery tracking dashboard.
IDCLE Tech LLPAUG 2019 -- NOV 2021
SOFTWARE ENGINEER · MUMBAI
  • Designed high-throughput Node.js backend for a Maharashtra State Government portal -- thousands of concurrent field officers, real-time data submission and reporting.
  • Led full-stack delivery: Angular frontend, Node.js API, MySQL database -- adopted by government offices across the state, delivered on time.
  • Engineered MySQL audit trigger system for tamper-evident DML logging with zero application-layer overhead.
  • Query profiling and index optimisation reduced p95 query times by over 60% across high-traffic endpoints.
  • Built cross-platform Ionic + Firebase mobile app for offline-capable field data collection.

Approach

Good backend engineering is mostly invisible. When the system is fast, reliable, and clear -- nobody notices. That is the goal. I optimise for the version of the code that the next engineer can understand at 2am during an incident, not the version that impresses in a code review.
