About

Java Backend Developer with 3+ years of experience building and scaling microservices for banking and fintech platforms, currently at Trustt (formerly Novopay) working on a credit-card platform serving 150,000+ active users. I design and own customer-facing journeys end to end — from database design and system architecture through production rollout. My work centers on making read-heavy, high-traffic systems fast and reliable: Kafka-driven asynchronous processing, Redis caching, database indexing and denormalization, and Elasticsearch-backed reads. Some things I've delivered: • Owned four independent customer journeys — Credit Card, Add-On Cards, Complaint Management, and Loan on Cards. • Improved onboarding success rates from 8% to 37% by redesigning retry strategies, workflow orchestration, and failure handling. • Cut average query response time ~40% through denormalization, targeted indexing, and Elasticsearch reads. • Reduced database load ~25% with Redis caching, improving p95 latency. • Integrated core-banking and third-party APIs (SOAP, REST, fixed-length) for transaction processing and reconciliation. My core stack: Java (8+), Spring Boot, Spring Security, Hibernate/JPA, Apache Kafka, Redis, Elasticsearch, MySQL/PostgreSQL, and microservices architecture. I care about clean, well-tested code, distributed-systems fundamentals, and pragmatic performance optimization. I also use AI-assisted engineering workflows (Claude Code with Jira/Atlassian MCP integration, custom agent skill files) to speed up delivery without cutting corners on quality. Open to Software Engineer / Backend / SDE roles where I can work on high-scale distributed systems. Reach me at abhishekpuranik08@gmail.com.
