Message

At my current stealth startup, I architected DesignA11y, an AI-native accessibility engine and Figma Dev Mode platform. Its SSE pipelines use Google Gemini 3.6 Flash Vision, reducing WCAG audit time by 75% for 10,000+ canvas nodes.

I also developed canvas geometry and alpha-blending algorithms to calculate contrast ratios across overlapping vector nodes, and integrated Figma's native Dev Mode Annotations API with bidirectional IPC sync.

At Unitron AI, I architected backend microservices and REST APIs with FastAPI and PostgreSQL, delivering 60%+ of the platform backend. I integrated OpenAI APIs with Google Workspace to automate workflows and cut manual content generation cycles by 70%.

At D. E. Shaw India Pvt Ltd, I built API testing and regression pipelines that accelerated execution by 60%, and refactored and tested enterprise backend enhancements. I also taught data structures, algorithms, and competitive programming at Masai School.
