What I'm looking for

I’m looking for a fully remote, async-first team where I can architect cloud-native microservices and event-driven data/FinOps platforms—while applying RAG/ML for anomaly detection and real-time insights.

I’m a Senior Software Engineer with 5+ years of experience architecting scalable distributed systems, microservices, and event-driven data platforms. I thrive in fully remote, async-first environments and enjoy turning complex data and reliability goals into shipped, measurable systems.

At Airtel, I architected a Java/Spring Boot + Kafka event-driven microservice platform ingesting 2TB+/day of multi-cloud billing data, delivering 98.96% uptime and savings-plan recommendations that cut cloud spend by 20%. I also built a real-time Anomaly Detection Service (Isolation Forest, One-Class SVM, DBSCAN, LOF, drift modeling) to achieve ≤5ms inference latency and reduce false positives by 30% at 72% accuracy.

I’ve built practical AI/ML and developer-facing experiences on top of production data. I delivered an LLM-powered natural language query layer over FinOps cost data using RAG (LangChain + OpenAI GPT-4), reducing analyst dependency by 35%, and I engineered 5+ PySpark & Scala ETL pipelines orchestrated on Apache Airflow into Apache Pinot & AWS S3—cutting reporting latency by 80% and enforcing multi-tenant FinOps tag-compliance governance.

Across payments, telecom, and cloud platforms, I focus on reliability, maintainability, and measurable impact. From integrating Deceased-Status APIs to prevent $50K+ in fraudulent transactions, to modernizing gateways (Gloo → Kong) and improving observability/MTTD by 45%, I pair solid engineering practices with hands-on ownership—while mentoring 4+ engineers and standardizing CI/CD with ArgoCD and Jenkins.
