Client & Goals A global blockchain innovator needed to delegate the full development cycle of a white-label cryptocurrency wallet to free up their in-house team. The wallet had to integrate with their existing DeFi ecosystem, support multiple currencies, and be ready for market launch as quickly as possible.
Client & Goals A London-based startup wanted to encourage users to abandon disposable plastic and switch to recyclable containers. Their idea: a cross-platform app that rewards users with in-app tokens for recycling plastic, which they can later exchange for eco-friendly products. They needed a team skilled in mobile/web development and machine learning for object recognition. Thanks to our experience with AI, ML, and digital currency solutions, we were selected as their tech partner.
I developed Linea, a cross-platform astrology app built with Flutter, that uses astrocartography to help users find the best places in the world to live, work, travel, and build relationships — all based on their date and place of birth. My responsibilities included implementing pixel-perfect UI from Figma designs, building reusable widgets, integrating REST APIs, and ensuring smooth animations and performance on both iOS and Android. I also optimized state management and handled data parsing to deliver a seamless user experience.
