I recently came across the Frontend Developer opening at your organisation and wanted to reach out directly.
At BlackNGreen (Product Based Company), I own the frontend for two AI Agent Builder platforms built on React — where I delivered a 30% improvement in performance and built real-time streaming pipelines with SSE and WebRTC. Before that, at Sirion.ai (Product Based Company), I designed ChatGPT-powered features that drove 40% higher user engagement and led the AngularJS-to-React migration across the platform.
5 years deep into React.js, Redux Toolkit, TypeScript, and Next.js — I care most about shipping fast, accessible interfaces that users actually enjoy.
I'd love a 15-minute call to explore how I could contribute to your organisation's frontend goals. My resume is attached for reference.
Best regards,
Kshitinjay Kumar
