At CimpleO Group, I built Go/Gin APIs and real-time processing for services spanning a Cocos client, Web3 integration, and Android native bridges. I used Go channels, Kafka, Redis Cluster, and MySQL to manage event state, asynchronous workflows, and transaction tracing.
At Pixelcabin Limited, I built React/Redux applications for business users and implemented data contracts with Ruby on Rails. I also built ETL workflows from external web services, files, and databases, and used RSpec to test key business flows.
At Ventures Lab Limited, I worked on a consumer-finance platform, building React features integrated with Node.js/Express APIs. I also contributed to legacy-code upgrades and tested user flows with Cypress, React Testing Library, and Puppeteer/TestCafe.
At Grayscale Limited, I delivered enterprise web and mobile features with React, Next.js, TypeScript, and Redux. In selected projects, I contributed to stock research, dental-practice management, and personal-finance products, and worked on real-time sports analytics and game clients.
