• Improved the Post Delivery Experience for Merchants, Eaters and Couriers as part of the Merchant Trust and Support charter of UberEats under the Delivery Engineering org.
• ▪️Streamlining Cancellation Policies:
• ➢ Investigated UberEats cancellation flows across multiple surfaces and micro-services. Identified policies scattered across application code and loosely managed configurations. Worked alongside tech leads from different orgs to design the solution for streamlining cancellation policies.
• ➢ Crafted a phase-wise project plan for incrementally delivery. Scaffolded the new infrastructure and instrumented several low-level details. Worked with Data team to craft an analytical SOT which helped Product Ops identify potential policy improvements with significant $$ impact.
• ▪️Instant Dispute:
• ➢ Investigated the limitations of existing Batch solution for Chargebacks and evaluated the migration efforts for an event-based solution. Co-led the high-level design to utilise Kafka, Cadence and Pinot. Instrumented low-level workflow implementations in conjunction with the Infra team.
• ➢ Architected the high-level design for a Batch Email solution utilising Cadence, Pinot and Bloc to inform Merchants about potential chargebacks. Built the low-level implementations for Batch Email workflow and coordinated with the different teams for global rollout.
• ➢ Integrated Citrus experiments and interfaced with Product, Ops, Data Science and Testing teams for experiment analysis and incremental release across global markets. Devised telemetry, monitoring and alerts to ensure visibility.
• ▪️Operational Excellence:
• ➢ Strategised Engineering Excellence initiatives across 7 engineers. Led the detection and elimination of 5K+ lines of dead code. Orchestrated the increase of unit test coverage from 82% to 95%. Executed graceful decommissioning for a legacy service leading to savings of $5K per year. Benchmarked and improved latency of a critical API endpoint from >230ms to <100ms.

• Helped facilitate expansion to several new marketplaces as part of the Platform and International team. Involved in planning and execution of monolith decomposition, improving code maintainability and optimising product lifecycle through feedback loop.
• ▪️International Remediation:
• ➢ Designed and implemented the remediation functionality for Coinbase customers from Australia and the UK. Since crypto laws are geo-specific to regulatory bodies, new requirements for KYC, IDP, EDV crop up regularly. The solution was designed to be highly configurable, reusable and scalable. It helped reduce time-to-market for future initiatives using a platformized approach. This also eliminated several repeated manual tasks which eventually reduced wasted IC bandwidth.

• Improved the efficiency of package tracking and visibility in the Shipment Tracking team under the Core Transportation Technology Org. Hardened and enriched a wide collection of micro-services responsible for ingesting and facilitating all updates across the life cycle of every Amazon package.
• ▪️TPS Quota Management System:
• ➢ Designed a sophisticated solution which moderates all outgoing calls to 3P systems for retrieving package updates while respecting the TPS limitations of external systems. It helped improve the scan ingestion latency of 20% of Amazon’s fulfilment volume spanning billions of packages per year across millions of customers. It operates at >1000 QPS during peak traffic and improved ingestion latencies from 50+ hours to <5 hours. The system uses a decision-tree based priority scoring algorithm for package tracking to ensure maximum utilisation of 3P API bandwidth.
• ➢ Devised a highly available, fault tolerant, distributed Priority Queue using AWS DynamoDB Global Secondary Index. It selects the highest priority packages which have greater probability to surface a critical scan in the near future relative to other live packages. Instrumented an API Scheduler based on a Producer-Consumer approach. It uses a fanout approach to schedule API calls for every package fulfilled by 3P carriers. It’s designed to operate in a lock-less manner with minimal memory footprint.
• ▪️Operational Excellence:
• ➢ Involved in triaging operational bottlenecks containing 5000+ security vulnerabilities across 30+ services. Led an 8 member team to triage critical risks, generated team-wide SOPs, drafted project plans and established delivery timelines to meet critical SLAs aimed at keeping our systems healthy.
• ▪️Hiring and Mentoring:
• ➢ Involved in 60+ interview loops across different engineering levels. Engaged in mentoring junior as well as mid-senior new entrants and bringing them up to speed for active participation in both long and short term projects.

• Joined as a campus recruit as part of Integrations team under Oracle Cloud Commerce org.
• ▪️Oracle Cloud Commerce:
• ➢ Instrumented scripts to automate Oracle Cloud Commerce API document generation. The scripts would recursively traverse, sanitise and transform legacy JSON documentation. Built an automation pipeline to convert updated docs to customer facing UI using Swagger.
• ➢ Built a cross-referencing widget which provides a generic template that lets 2 different systems interact with each other using (Key : Value) pairs. Instrumented an error handling framework that captures a log of all functional and connection errors and helps detect their root cause.
