Mykhailo (Mike) Severa

Architected and led a small team building an AI-native leadership platform: a multi-agent system (interview, aggregation, follow-up, chat, and weekly check-in agents), RAG over a vector store, and real-time voice — on a NestJS + GraphQL + PostgreSQL backend and a Next.js frontend. Built on a spec-driven, agentic workflow with codified guardrails to keep AI-generated code production-grade.

Built an AI-powered Gmail assistant that reduces email workload by generating context-aware, tone-aligned replies directly inside the inbox.

• Composer AI - an AI agent that reads thread context, retrieves relevant information (past emails, sender history, calendar events), and drafts thoughtful, tone-accurate replies instantly through the web app and Chrome extension.

I co-founded and built this product end to end: mobile and web, a microservice backend (Node.js + Python), AI agent orchestration, a real-time voice agent, and GCP deployments.

• Gogue AI- A mobile app that lets you create deeply personalized audio lectures based on credible books and research, tailored to your specific problems. It lets you explore, save, and resume audio lectures with full background playback. When you want to dig deeper, you can chat with an AI about your notes or even talk to a real-time voice agent that captures insights and creates notes as you speak. It feels like listening to a podcast, studying with a tutor, and keeping structured notes—all in one place.
