Krupal Joshi
Game Developer | HTML5 slots and AI agent workflows

Profile
I’m a game developer with 5 years of experience in iGaming, working with TypeScript, PixiJS and HTML5. My career has also taken me through technical sales, account management and teaching in the UK and overseas. Those roles involved understanding what people needed, explaining unfamiliar ideas and adapting to different audiences. That experience still influences how I work with colleagues, customers and stakeholders.
In game development, I’ve taken features through to release, contributed to framework improvements and supported teammates through code review and mentoring. I’ve also taken on product-owner responsibilities and run scrums.
More recently, I’ve been developing practical workflows with Claude Code and Codex, including reusable instructions, project knowledge and checks on generated work. I’m enthusiastic about exploring what these tools can contribute to game development and learning through building and testing.

Playable prototypes
Built prototypes and a slot demo with anticipation, turbo/autoplay and bonus-trigger presentation, plus reel animation-timing controls and portrait/landscape layouts.
Review gates
Organised subagents into research, build and review roles, combining existing browser MCP tooling, type checks, regression tests and mutation probes.
