SDE - Backend at ARRISE powering Pragmatic Play, Apr 2025 - Present · 1 yr 5 mos, Noida, Uttar Pradesh, India, ● Architected a scalable Swap Management platform enabling employee-to-employee shift swaps for single-day and multi-day requests on published rosters, working - RDO (Specific Day Off) swaps, with shared business validations and WFM manual override flows, delivering self-service automation while maintaining operational controls. ● Refactored a legacy Swaps module using Strategy + Factory patterns into clean, extensible components for Published and Unpublished roster scenarios (including Specific Day Off), eliminating nested conditionals, centralizing common validations, and significantly improving code readability, testability, and feature onboarding velocity. ● Improved API performance by 50% by eliminating redundant database calls through DTO-driven processing; introduced a fetch-once-and-evaluate design where all swap data was aggregated into a single internal DTO and reused across validations, reducing DB load and improving response consistency. ● Implemented complex domain validations including work norms, consecutive day limits, and team capacity checks within a shared validation pipeline, enabling automated approvals that cut WFM manual workload by 98%, with fallback manual override flows for operational edge cases.
Software Development Engineer at Amazon, Sep 2021 - Jan 2024 · 2 yrs 5 mos, Hyderabad, Telangana, India, ● Integrated real-time address inline suggestion functionality for Australian forms by developing scalable RESTful APIs using Java and Spring Framework, improving address prediction accuracy and user experience. ● Designed and implemented a Customer Delivery Profile platform for India, capturing structured address attributes that contributed to a 25% reduction in Last Mile delivery failures and enhanced delivery accuracy. ● Developed localized Address Wizard Forms for international marketplaces including Turkey and Netherlands, increasing form completion rates by 25% and reducing address-related delivery failures by 12%. ● Built and deployed a high-throughput benchmarking framework for a Tier-1 Central Service to measure maximum instance capacity, enabling 30% improved scalability and 20% latency reduction during peak traffic events. ● Conducted root cause analysis for critical Tier-1 service defects, reducing issue resolution time by 40%, and migrated VIPs to a Least Connections load balancing algorithm, enhancing overall system stability. ● Implemented a robust data ingestion pipeline to transform hierarchical graph data from relational databases into Elasticsearch, enabling fast and accurate address suggestions at scale. ● Collaborated cross-functionally to optimize infrastructure and load balancing strategies, ensuring high availability and performance during high-demand periods such as Prime Day and festive sales.
