Work Experience

LetyMind

FullStack Engineer

2023 - Present

I implemented automated messaging using n8n and Hono, reducing manual processing by sending reports and workflow notifications via WhatsApp and email. I also built an error-handling workflow that triggers Discord alerts for failed messages, and am currently developing the platform dashboard to enhance operational efficiency.
