Key Contributions:

• Lead the migration from monolith to microservices, enabling faster deployments, improved fault isolation, and service-level scalability.
• Managed and mentored a 15-member engineering team, overseeing backend architecture, code reviews, and cross-functional delivery.
• Contributed to BigBasket’s scale-up journey from an early-stage startup to a unicorn, driving platform reliability and performance.

Auto Assignment

• Designed and implemented an event-driven architecture to automate delivery route assignments across the logistics platform.
• Reduced average assignment time from 10 mins to 2 mins, impacting 2.5L+ routes daily and saving 33L+ operational minutes per day.
• Eliminated bottlenecks in manual workflows, improving dispatch speed, scalability, and system maintainability.
• Enabled real-time responsiveness and decoupling of services for future extensibility.

Routing:

• Architected and implemented an event-driven routing system to automate route generation for daily order deliveries, replacing manual scheduling with scalable, asynchronous workflows.
• Addressed early load bottlenecks by introducing partitioned topics and multiple consumers, enabling parallel processing and improving throughput under peak volumes.
• Enhanced system resilience by integrating a dead letter queue (DLQ) with retry logic for failed events, ensuring reliable and fault-tolerant execution.
• Collaborated with cross-functional stakeholders for requirements gathering and design alignment, improving delivery efficiency and operational predictability across regions.

CEE Ledger System

• Led the design and development of the CEE Ledger, an enterprise-grade system for automating cash-on-delivery (COD) collections from delivery agents.
• Integrated with multiple banking partners to enable real-time, secure reconciliation of physical cash to digital records.
• Integrated the already existing payout system to deduct cash collected by the cee from his salary.
• Reduced manual cash exposure by ₹15 Cr (from ₹40 Cr to ₹25 Cr), minimizing financial risk and increasing auditability.

Digital Cash Collection via UPI & Airtel Integration

• Introduced UPI and Airtel cash deposit flows within the delivery agent app to enable fast, secure, and branchless cash deposits.
• Eliminated the need for deploying expensive cash vending machines at each store, resulting in cost savings of ₹10 Cr.
• Ensured seamless integration with backend cash reconciliation systems, improving traceability, reducing handling risks, and accelerating settlement cycles.

Multi-Tenant Integration for SaaS

• Led the architectural design and implementation of a multi-tenant SaaS framework, enabling support for multiple clients with isolated data and shared codebase.
• Introduced modular abstractions and configuration-driven behavior, minimizing code duplication and tenant-specific branching.
• Ensured backward compatibility of existing modules across tenants with minimal refactoring, reducing regression risk.
• Improved platform scalability and maintainability, reducing onboarding time for new clients and simplifying future feature rollouts.

CRM Integration APIs for Customer support platform:

• Architected and implemented RESTful APIs exposing order tracking and fulfillment data to external CRM vendors.
• Ensured real-time data consistency, secure access (authentication & authorization), and high availability under production load.
• Collaborated with cross-functional teams and external partners to define integration contracts and troubleshoot edge cases.
• Enabled plug-and-play integrations with CRM platforms, reducing partner onboarding effort and improving SLA adherence.
• Instrumented APIs with monitoring, logging, and alerting to ensure stability, traceability, and quick incident response.

• Participated in the end-to-end development of a social media platform enabling users to share, edit, and post content.
• Built and maintained a document management system for the Water Department, Govt. of Jharkhand.

• Contributed to development and maintenance of multiple client-facing projects.
