Darshan Jain

I’m a backend engineer with 4 years of experience building high-throughput distributed systems, specializing in event-driven services, scalable APIs, and performance caching. I leverage Java and Spring, along with Kafka and PostgreSQL, to drive end-to-end feature delivery—especially in FinTech and AI-adjacent backend infrastructure.

In my current role, I’ve reduced partner onboarding time from 4 weeks to 1 week by architecting an extensible co-lending system with configuration-driven orchestrations and explicit state transitions. I also scaled backend services to handle 100,000+ API calls per hour by enforcing API contracts and coordinating across 3+ teams.

I focus heavily on production performance and developer efficiency—introducing Redis-based session/read caching to cut repeated auth calls and database load, and using GitHub Merge Queue to reduce CI/CD compute costs and runtime by ~10–15%. I’ve also built an internal AI debugging copilot using a RAG-based approach over the codebase, Jira history, and GCS logs.
