Software Development Engineer

Namma Yatri (Juspay)

Jun 2025 - Present

Developed production REST APIs powering fleet analytics for the Maruti Suzuki operator dashboard, processing driver, vehicle, and ride metrics across 20+ dimensions using ClickHouse and PostgreSQL with Redis caching, reducing query latency by 60%. Architected remote development infrastructure for 30+ microservices, migrating local workloads to shared cloud instances and reducing per-developer local resource usage by 80% through SSH PTY tunneling, automated rsync deployment, and per-developer port isolation. Automated backend financial recovery systems for driver penalties, automating 5+ financial workflows including GST-compliant fee pipelines, invoice aggregation, vendor split settlements, wallet deductions, and UPI mandate autopay reconciliation. Designed a cross-platform Driver Cancellation and Penalty backend service with predictive blocking and slab-based penalty rules, automating driver suspension and penalty workflows across the platform. Optimized dev-box builds by offloading Nix compilation to a shared remote nix-daemon, enabling CI-cache-based incremental builds and pinning the CI GHC toolchain, eliminating full recompiles and cutting build times by 70%.

Software Engineering Intern
