At MiCalls, I designed reliability systems for an AI voice and omnichannel agent platform, including monitoring, fallback handling, workflow constraints, and escalation triggers. I also designed human-escalation paths for conversations automation couldn’t resolve.

At Mexil Software Solutions, I work directly with clients to investigate issues, reproduce problems, and explain fixes and timelines. I built real-time messaging across web chat and WhatsApp Business API, with Twilio, Socket.IO, and Redis.

As Chief Technology Officer & Lead Full-Stack Engineer, I design secure REST and GraphQL APIs and lead technical direction for SaaS, fintech, and CRM products. I’ve also integrated AI chatbot features and payment workflows.

Earlier at Mexil Software Solutions, I implemented Playwright end-to-end testing and Jest and Mocha unit testing, and built production React and Next.js applications. I’m comfortable working autonomously with remote, cross-timezone teams.
