Delivering production changes across backend services, web and mobile clients, payments, and infrastructure for ELSA's global learning products:

• Performance: Diagnosed checkout latency from production traces and introduced request-scoped caching that reduced repeated Stripe catalog requests from 15 to 2, eliminating ~2.6 seconds of external-service latency in a production-shaped benchmark while keeping mutable payment state safe.
• Platform: Standardized staging and production release workflows across a 27-repository web estate, aligning main-branch staging deployments with version-tag production releases.
• Localization: Corrected locale normalization across B2B and content services, enabling translated AI role-play titles and objectives across country and language variants.
• Delivery breadth: Shipped improvements across 22 repositories spanning Python services, TypeScript web applications, Flutter clients, payments, CRM, SEO, and infrastructure.

Delivered platform and product improvements across customer, driver, and merchant applications for Be's multi-service ecosystem:

• Platform: Established CI/CD pipelines for 5 applications and organized 20+ shared packages into Dart Pub workspaces, giving teams consistent builds and dependency management.
• Integration: Built end-to-end debug tooling across native and Flutter layers to simplify diagnosis of cross-platform issues.
• Product systems: Developed Help Center case management and a configuration-driven form builder reused across customer, driver, and merchant experiences.
• Business delivery: Shipped loyalty, voucher, ride-hailing, and driver products; subscription and stacking-promotion initiatives were recognized internally as projects of the year.

Built products across Flutter mobile and Flutter Web, including a ticketing application used to distribute millions of tickets globally, an event-organizer back office, and an internal operations portal.

• Added automated acceptance coverage with Flutter Driver and Cucumber.
• Built reusable UI and recreated an administration tool for the web, expanding a mobile-focused codebase into operational workflows.

Developed vCloudCam, a cloud-based video surveillance iOS app using Swift, Objective-C/C++, and OpenCV; built image rotation, cropping, resizing, and YUV420-to-RGB conversion workflows.
