Mykhailo (Mike) Severa

Hi, I'm Mike, a Principal Product Engineer and Entrepreneur with 15+ years building and shipping web and mobile products, now focused on AI-native development: multi-agent systems, RAG, vector search, and real-time voice. I love creating things and thrive where speed and technical research matter. My strengths are fast learning and a product-oriented mindset. Outside of work, you'll find me spending time with my family or learning piano and drums.

Experience

Principal Product Engineer, AI Leadership (Feb 2026)

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.

  • Thought Partner - an AI-native leadership platform where teams run AI-facilitated interviews and workshops, align company and personal goals, and stay on track with weekly AI check-ins — backed by an always-on chat and voice thought partner with RAG and long-term memory.

Co-founder & Product Engineer, Gogue AI (May 2025)

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.

AI Engineering

I build AI-native products end to end — multi-agent systems, RAG, vector search, and real-time voice. Recent work includes a 9-agent platform on the Vercel AI SDK with Braintrust evals, RAG over a Turbopuffer vector store, mem0 memory, and ElevenLabs voice. I also run a spec-driven, agentic engineering workflow (OpenSpec across Cursor, Claude Code, and Codex).

Foundations: Stanford/DeepLearning.AI —
