● Owned architecture and delivery of an LLM-powered calendar experience serving 12M+ Alexa users at ~7000 TPS with 99.99% uptime

● Proposed a push-based update architecture to replace polling, reducing sustained load from ~7000 TPS to ~800 TPS org-wide and significantly improving scalability

● Set up and regionalized the Calendar Expert, authored instructions for new features, and partnered with science to improve top-level date/time understanding and parsing accuracy

● Architected and productionized a distributed, fault-tolerant Remarkable Alexa service, establishing reliability patterns adopted across the organization

● Implemented resilience patterns (caching, retry/backoff, fault isolation) to enable graceful degradation

● Defined and implemented externalized service APIs and front-end data contracts, enabling scalable integration patterns across backend and mobile clients

● Led a team of 5 engineers to deliver recurring calendar events, increasing customer retention by 38%

● Enabled EU and FE expansion of the LLM-powered Alexa calendar service by resolving ZAZ migration, provisioning, and KMS dependency blockers

● Architected the React Native data layer, transitioning from calendar-only retrieval to a unified calendar-and-reminders model with caching, pagination, and real-time updates

● Redesigned the metrics pipeline, improving reporting and reducing recurring operational load by 14%

● Improved onboarding conversion by 8% by fixing pain points in the OAuth linking funnel

● Architected a promotions platform that increased order volume by 18% and AOV by 8%

● Owned instrumentation-led performance optimization, reducing memory by ~42%, improving render latency by ~55%, accelerating time to interactive, and shrinking APK size by 2.7x (46 MB to 17 MB)

● Architected and institutionalized the Android CI/CD pipeline, establishing the deployment standard across multiple mobile applications

● Integrated Google Pay checkout, partnering with Google for certification and establishing a reusable foundation for future payment methods

● Architected the white-label mobile platform, generating six-figure revenue and implementing automation scripts that streamlined and scaled partner onboarding

● Built deep-linking and campaign attribution infrastructure, enabling scalable growth and marketing integrations

● Spearheaded the push to React Native which drastically increased our ability to adapt to changing business needs

● Led the design and development of an Android application to gamify amateur sports

● Built a prototype which had feature parity with our production application using React Native

● Refactored the codebase to follow reactive design patterns by integrating RXJava into the codebase

● Built an Android application which checks the user's social media profiles like Facebook and Twitter for usage of certain hashtags and rewards them based on that

● Used AWS to deploy the required backend to serve the front-end application

● Worked on designing a Micro-Kernel for a custom SoC based on the RISC-V instruction set architecture
