I build dependable Java backend systems for telecom and banking platforms at scale.
IndiaWhat I'm looking for
At LTIMindtree, I build backend infrastructure for banking and financial services, including secure REST APIs for core banking integrations and a greenfield investment platform for the Indian retail market.
Previously at Black N Green Mobile Solutions, I maintained carrier-grade USSD session handling and SIP/SS7 call flows while building Kafka pipelines that processed millions of call records daily for billing, fraud detection, and reporting. The telecom systems I supported sustained 99.9%+ uptime across two years.
I also led backend development for data deposit engines at Platform 3 Solutions, creating ingestion and transformation logic, PostgreSQL schemas, profiling utilities, and integration connectors for high-volume relational data.
I work end to end, from API and data-model design through Docker deployments, Jenkins CI/CD, observability, and production performance tuning. I bring experience across Java, Spring Boot, Kafka, PostgreSQL, telecom protocols, core banking integrations, and event-driven systems.
