Key Technologies: - Fullstack (backend, frontend, client/server, cloud) solutions. - Systems software development (Rust, Golang). - Artificial Intelligence components, bots, and more. - Blockchain (all tiers) as well as smart contract security auditing and design. - and of course video game development as most freelancers experience over their careers. Professional Accolades: My dedication to innovation and excellence is evident in my participation in four XPRIZE competitions, where I've had the privilege of collaborating with brilliant minds to tackle some of the world's most pressing challenges. These experiences have not only broadened my horizons but have also instilled in me a relentless pursuit of perfection and a commitment to pushing the boundaries of what's possible.

    I am a seasoned Full-stack Developer and MSc Research Assistant at the University of Alberta, with extensive experience across front-end, back-end, and full-stack roles. My journey in the tech industry spans numerous domains, including AI, machine learning, dashboard development, and web applications, where I’ve consistently delivered high-impact solutions. At the University of Alberta, I’ve conducted research on computer vision systems to detect borderline personality disorders, leveraging machine learning and convolutional neural networks (CNNs) with Python and PyTorch. My role also involved creating a German research data database for predicting marriage outcomes, a project that required advanced data handling and AI/ML integration. My academic and professional pursuits have allowed me to work with cutting-edge technologies like OpenAI's GPT-4, FastAPI, and large-scale data visualization tools such as Tableau. In industry, I’ve contributed to high-profile projects as a Full-stack Developer. For iMoney Tools, I provided back-end refactoring using Strapi and GraphQL and fixed front-end issues with React and Next.js to ensure a responsive, accessible user experience. At GammaEdge, I built a stock data dashboard, implementing complex financial calculations and interactive visualizations, and deployed it to an AWS EC2 instance. Additionally, my work with Tactacam involved developing an admin dashboard and adding RESTful API endpoints for payment management, leveraging Vue, AWS, and Stripe for a smooth deployment experience. My development experience includes building scalable applications and designing specialized APIs, as demonstrated at Alteryx, where I integrated RESTful APIs on the React front end and built SOAP APIs with JWT-based authorization using the Spring Framework. As a Senior Front-end Developer at ClassDojo, I led the creation of custom UI components with React and TypeScript, ensuring robust functionality with Jest and Cypress testing. In addition to these projects, I’ve had a broad consulting career, working with a diverse tech stack—React, Angular, Node.js, C#, Python, and Django—while delivering enterprise solutions in data-intensive environments. As a technical architect and consultant, I’ve advised clients on software architecture and managed full-cycle development projects, often overseeing teams and complex systems for engineering clients. My technical repertoire spans cloud platforms, including AWS and Heroku, as well as a deep understanding of data visualization, large-scale architecture, and responsive web and mobile design. With a passion for solving complex technical challenges and a commitment to innovation, I continue to apply my skills to projects that drive real-world impact in AI, machine learning, and full-stack development.
