Hello, my name is Kunal Khanwalkar and I'm a Software Engineer.
I've worked on all sorts of fields namely Backend Services, Cloud Infrastructure, Distributed Systems, Native and Web Applications, Android App development, Scripting and Automation; which is backed by my 5+ Years of Experience in top MNCs.
Outside of work, I have a second full time job of maintaining the Tapri-infrastructure (homelab joke) and spend time with my fellow Teatotallers(TM) working on oblique(TM) project intakes. I implore you to check out my oblique(TM) Business Partner Tapri-stack on Github.
You can download my RESUME on the top-right corner.
Experience
Amazon — Software Development Engineer
July 2022 — Present
Amazon Fresh India — Warehouse Management & Supply Chain Systems
May 2024 — Present
- Authored a Principal-reviewed RCA resolving a critical INR 59M accounting discrepancy. Designed and executed a Multi-threaded Python reconciliation script to query ledgers and virtually reverse-transship inventory, coordinating across 5+ organizations. Executed 70k+ inventory mutations row-by-row to guarantee zero-operational downtime, avoiding an INR 1.2M loss.
- Architected and executed the pilot region migration strategy from eu-west-1 to eu-south-2 for the Liquidation Service. Rewrote legacy CloudFormation to AWS CDK, migrated stateful data via S3 CRR and DynamoDB exports, and utilized traffic switching for zero-downtime migration. Architected async-workflow (SQS/EventBridge) migrations for 2 additional services.
- Led a Cross-ORG level talk of Region Migration as the Region Migration POC of my ORG.
- Designed the LLD and Java implementation for 2nd/3rd Level Blind Cycle Count feature across 32 FCs and 400+ stores, unblocking an INR 100M WMS migration. Devised a persistent state-management strategy for short-lived tasks and complex lock-in logic on inventory count. Designed the system to be extensible for N-th level counts and K inventory attributes via configuration changes.
- Directed monthly ORG-level reviews for on-call health, CI/CD, and infrastructure cost for services owned under my team. Built an AI-powered Python platform automating cross-API data fetching, ticket bucketization, and RCA analysis via AWS SageMaker, reducing report creation time from ~2 days to ~2 hours per month per team, currently adopted ORG wide.
- Led the team-wide JDK 17 migration (6 services, 11 pipelines), refactoring deprecated reflection and class-loader patterns. Migrated frontend tools from AngularJS to React, utilizing useRef for optimal canvas rendering, and automated manual inventory on-call SOPs via python scripts (saving 2.5 hrs/rotation).
- Launched 11 XPT nodes and migrated 3 FCs to the new HWMS, delivering INR 143M/m in operating cost savings. Owned the node-launch SOP, coordinating with cross-functional step owners to streamline future rollouts.
Technologies: Java, Coral, Spring Boot, AWS, AI w/ Sagemaker, CDK, React, Python
Alexa Built-In / xApp Platform
July 2022 — April 2024
- Designed and deployed the Ambient Home (‘Show Mode’) feature for third-party Android tablets using React/TypeScript, C++ and websockets. Architected an extensible settings management framework utilizing the Observer Pattern, enabling dynamic backend setting propagation without native C++ changes and establishing the foundation for all upcoming native features.
- Led native build-system optimization initiatives reducing developer build times from ~2 hours to ~30 seconds. Overhauled the existing CMake/Make and bash build scripts by supporting incremental compilation of linked libraries. Engineered a unified build script across fragmented platforms (Samsung, LG, Android, etc), deprecating siloed team scripts.
- Owned the xApp Android platform launch on Android devices, driving Non-Functional Requirements (NFRs) and executing a comprehensive codebase refactor. Reduced memory footprint by 30% and storage usage by 12% by optimizing expensive code paths and removing unused artifacts. Acted as a SME for external team members and took responsibility for maintaining Code Standards for away teams.
- Authored the Low-Level Design (LLD) for the Channel/Lineup integration on 2023/2024 Samsung TVs. Developed a new Device Abstraction Layer (DAL) API to bridge native partner devices with the Alexa Channel Controller backend service, with architecture reviewed by Principal Engineer and Sr. Solutions Architecture.
- Led the RCA and production hotfix (v2.3.1) for a critical log-streaming outage during the 2024 Samsung TV launch. Owned the end-to-end deployment, generating dedicated release branches, version-sets, and a new automated AWS CodeCommit CI/CD pipeline to deploy the hotfix binary.
- Built the foundational load-testing framework in Java for 4 xApp backend services, integrating with internal testing tools to enable rigorous pre-production performance and scalability validation.
Technologies: C++, Java, TypeScript, React, Android, AWS, Linux, CMake, Make
