Where I've built things that matter.

Oct 2021 โ€” Present

Senior Software Engineer

Data Dynamics Inc. ยท Pune
  • Architected a high-performance content-scanning microservices ecosystem, transitioning from legacy Apache NiFi to a scalable Kafka-driven architecture; integrated BERT-based NER models for sovereign PII scanning with 95% accuracy.
  • Led modernization of 14+ microservices, migrating to Spring Boot 4.x and JDK 25; hardened security and supply-chain governance via automated Snyk-integrated CI/CD.
  • Engineered a high-throughput ingestion pipeline achieving a 30% Elasticsearch ingestion gain through optimized Kafka consumer distribution and async client patterns.
  • Integrated Claude Code into daily dev & design workflows to automate boilerplate, accelerate prototyping, and lift sprint velocity.
  • Designed real-time dashboard APIs and multi-processing file-parsing services that prevent resource exhaustion during peak traffic.
  • Established Elasticsearch ILM policies and risk-scoring indexing for long-term observability and compliance.
Feb 2020 โ€” Oct 2021

Software Associate

  • Built a travel-quote booking chatbot with Google Dialogflow plus NodeJS webhooks, delivered for Reliance General Insurance within a one-month timeline.
  • Architected an API-driven Common Fleet GPS tracking system from scratch (Spring Boot + MySQL), integrating multiple third-party GPS providers.
  • Directed and mentored a team building Angular apps with complex Google Maps API integrations.
