    Simplifying and solving complex and complicated business problems. Dual-Experience at a very well-known successful startup and a FAANG company teaching me how to handle and manage scale and complexity. My thoughts: "Prefer Quality over Quantity" "I'm Asynchronous" With software development, there is always something new to discover. Designing systems that are truly helpful to the business and customers is my ultimate goal on every project. Just to walk you through some of my work-ex in the corporate projects, here I have some to show-off: During my current role @ Amazon, I worked at multiple projects, here are some key ones: 1. Designed & developed exchange order to POD order conversion: There was a burning issue where incase of exchange orders, if the delivery associate rejects the old product to be exchanged at the doorstep, the order has to be cancelled(bad customer-experience). With this project, the customer's pain point will be removed and the customer can choose to pay the reduction s/he got via POD then and there and avoid order cancellation. I had implemented this end-to-end, meaning to say that I took the ownership and made the required changes in upstream & downstream team's systems too. This was done using stacks like Herd, SQS, DynamoDB and other proprietary frameworks. 2. Convergence Converging campaign setups and rewards from 4 teams to a single team. Unified evaluation across clients on common Rewards platform. This enabled us to extend capabilities like payment offers on operators; coupon as a benefit across all clients. This in turn helps us increase in % rewarded txn across all clients. Single point for creation and modification of cashback and coupon campaigns for LPA/HFC/BOSON on Unified Rewards Console. Operational Efficiency: This is expected to save ~175-200 hours per month for these 3 clients alone across design, marketing and category. Engineering Efficiency: IMR reduction of ~ 6.5K$ per month from AWS env Financial Efficiency: * Centrally limit customer benefit across promotions to avoid double dipping * Eliminating manual errors (on set-up & targeting) and addressing leakages through simplified set up and centralized audit & approval process will lead to an annualized savings of $2.5MM across cost/MAU Stint @ Ola(key point): 1. Developed the Ola Lite/PWA's async orchestration backend from scratch using Vert.x in java
