At Capital One since November 2023, Vladyslav Khambir has made substantial contributions to the company's mobile banking platform. He implemented the Discover feature integration following the merger, enabling the migration of over 500,000 Discover users to the Capital One app. He delivered late-night credit card payment support by extending the cutoff from 8 PM to midnight, helping more than 20,000 users avoid late fees daily. He led the migration to a new user behavior tracking library and built release-specific user funnel dashboards that enable post-release behavior analysis. He created and demonstrated a comprehensive UIKit-to-SwiftUI migration strategy, successfully migrating four major plugins and driving team-wide adoption of SwiftUI. He developed a visual difference testing proof of concept that was adopted by the platform team, resulting in snapshot test coverage for hundreds of design system components. He improved the credit card autopay feature by enabling users to schedule payments weekly and biweekly, reducing missed payments by an estimated 10%. He partnered with back-end teams to create a tool for monitoring QA APIs, ensuring stability and issue resolution while saving thousands of engineering hours annually. He mentored and onboarded two team members, guiding them through processes, codebase, and technical best practices. He rectified date issues that prevented users in the European time zone from creating payments. He attained CSSE and AWS certifications, held a demo for technical teams about development instruments for static code analysis, and became certified as a Capital One interviewer, actively participating in the hiring process by conducting technical interviews and evaluating candidates for iOS roles.
Before joining Capital One, Vladyslav Khambir served as Lead Software Engineer at SKELAR from July 2020 to November 2023. He developed an approach for integrating SwiftUI within a UIKit project, resulting in a 100% transition to SwiftUI across all app screens. He collaborated with the product and design teams to integrate Spanish localization into the mobile application, resulting in a 20% user base expansion and a launch in a new market. He initiated and managed the integration of end-to-end testing into the development lifecycle, resulting in a 60% decrease in manual smoke QA efforts. He enhanced the application's stability, achieving a 99.9% crash-free rate with 80% unit testing coverage. He optimized development workflows by automating code reviews and implementing CI/CD pipelines, resulting in a 15% increase in task capacity due to time efficiency gains. He executed an A/B test to implement a subscription model, leading to a 10% boost in revenue. He facilitated the creation of project management processes using agile methodology for the development team, resulting in enhanced predictability and the establishment of a clear workflow. He led the split of an application into functional modules, enhancing scalability and enabling module reuse across three apps. He delivered the MVP to users within two months, which grew into a substantial project and achieved a top three ranking in the category Magazines & Newspapers on the US App Store.
Prior to SKELAR, Vladyslav Khambir worked as a Software Engineer at MLSDev Inc. from October 2017 to July 2020. He implemented a software solution for couriers of a food delivery service in the US with an offline mode, enabling the completion of orders without an internet connection for over 25% of total orders. He built an iPadOS enterprise solution with a reusable architecture for shared system components across two apps. He released RTL interface support to enhance the UI/UX and accessibility of the application for users in Arabic-speaking regions. He engineered the iOS framework RxLocalizer, facilitating seamless app localization for developers, which currently has garnered over 100 stars on GitHub.
From July 2016 to September 2017, Vladyslav Khambir served as a Software Engineer at Checker in Kyiv, Ukraine. He created the MVP in six months for online grocery ordering and delivery as a key tool in presentations to potential investors. He designed prototypes using iOS SDK that clarified and translated business ideas into specific development goals.
