Mid-level Front-End Developer specializing in React and TypeScript

Regina, SK5y exp

“Frontend engineer who has led end-to-end builds of complex React + TypeScript workflow editors (multi-step scenario builder with nodes/connections/conditions) with strong quality practices (CI/CD, unit tests, schema validation, logging, feature flags). Also delivered an AR flower-placement feature during an internship at Ecomspiders, rebuilding the experience with Three.js, live camera preview, and surface placement tested across devices and lighting conditions.”

“Backend/integration-focused software engineer who built and debugged a complex location modeling system (data pipelines, APIs, optimization logic connected to a dashboard). No direct ROS/robotics experience yet, but demonstrates strong distributed-systems debugging, containerized deployment (Docker), and CI/CD/testing practices and is actively looking to pivot into robotics software.”

Senior Front-End Engineer specializing in React/TypeScript and Next.js for FinTech & SaaS

Calgary, AB9y exp

“Frontend engineer with deep experience in crypto/fintech products, including leading a Next.js/TypeScript crypto wallet and microfrontend platform at 200–300k daily transactions and building a real-time trading dashboard. Strong in scalable architecture (microfrontends + BFF), quality systems (Storybook, testing, Sentry), and performance optimization (including a 30% bundle-size reduction), with proven feature-flagged rollouts and iterative delivery.”

“Frontend engineer who led an enterprise Vue 3 product end-to-end with a feature-based architecture and Pinia state management, with a strong emphasis on accessibility at scale. Created and published an accessibility library (vue-a11y-directives) used in a production front-desk app (Hotelkeyapp) and by other developers via npm.”

“Built and shipped a production "Campaign AI" multi-agent system (LangGraph) that personalizes B2B outbound emails at scale using Apollo.io prospect data, clustering-based segmentation, and 21 persona variants. Notably uncovered that high click rates were largely email security scanners and created a validated bot-detection/scoring pipeline (timestamps/IP/user-agent/click patterns), bringing reported engagement down from ~40% to a trusted 5–8% that aligned with real conversions.”
