Software Engineer 2, Fusion Data Intelligence Platform

2025 - Continuing
  • • Designed and deployed a distributed auth and access control system using OCI Resource Principal and Coherence-based session caching — enabling secure, low-latency cross-tenancy communication across OCI services without per-request credential overhead.
  • • Built and operate high-throughput microservices and real-time streaming services on Kubernetes + OCI Streaming + ATP serving 1M+ daily users — designed for fault tolerance with circuit breakers, retry budgets, and latency SLOs enforced at the service layer.
  • • Architected an AI-driven observability sidecar that attaches to distributed jobs, captures execution traces, and runs automated root cause analysis — reduced engineer triage time by 40% and cut reactive debugging load significantly across the team.
  • • Developed a real-time anomaly detection service over live pipeline metrics — applies per-tier failure thresholds and predictive signals to fire pre-emptive alerts before cascading failures, reducing production downtime risk by 30%.
  • • Improved large-scale query performance through adaptive caching, parallel execution tuning, and workload-aware scheduling — delivered 15% faster P95 report latency on high-cardinality analytical datasets with no schema changes.
  • • Tech stack: Java · Python · Go · Distributed Systems · Microservices · OCI (Dataflow, OKE, Streaming, ADB/ATP) · Kubernetes · Docker · Git

Tata Consultancy Services

Software Developer, Data and Digital Infrastructure Services

2021 - 2025
  • • Re-architected a distributed job orchestration engine using Go, Kafka, and PostgreSQL, replacing a legacy PHP service and boosting SQL analytics performance by 64 %.
  • • Migrated 4.2M + daily async tasks to Pub / Sub, Spark, Hadoop, and Delta Lake, improving throughput and cutting infrastructure cost by 68 % across 300GB / day batch + streaming pipelines.
  • • Built BigQuery - driven data lake backup and asset discovery services, improving compliance and data governance efficiency by 30 %.
  • • Developed a low - latency GraphQL Data-as-Service API(300ms P95) processing 3.5TB / month, reducing latency by 60 % and scaling to 3× traffic.
  • • Automated CI / CD with Docker, Kubernetes, and GitOps, reducing deployment lead time by 50% and increasing rollout reliability.
  • • Launched GHD Rover, an AI- powered enterprise search platform using Hugging Face + vector databases, achieving 88.4 % accuracy with personalised LLM recommendations.
  • • Tech stack: Python, SQL, Kafka, Spark, Go, Hadoop, AWS, GCP, PyTorch, web services, cloud infrastructure.
