Lenka Kadlec · Senior AI Product Engineer & Tech Lead · Ex-Microsoft

Remote-only. No agency markup, no ramp-up overhead. A senior engineer who makes decisions and ships - including the AI features most teams can't get past the demo stage.

What you get

Two ways to work together

Whether you need a product built or a senior pair of hands on your team, the engagement is scoped, senior, and low-overhead.

End-to-end delivery

I build and ship your product - architecture to deployment - solo.

  • React, Next.js, TypeScript, Node.js, PostgreSQL
  • AI integrations: agents and in-app actions that do real work, not chat widgets
  • Senior tech lead - makes decisions, doesn't wait for tickets
  • 4-week packages through long-term partnerships
  • Remote only · US & EU clients

SoundAgent
AI agent · voice-driven SaaS

Real-time collaboration, role-based access, and subscription billing built in. Currently in beta, being hardened for release.

Video Verifier
AI fact-checking · cost-modelled pipeline

A full-stack app that turns any YouTube video into per-minute summaries, key points, and a “chat with this video” experience. Pulls the transcript, summarizes with Claude, extracts claims, and verifies each against web sources. Built end to end: durable background workflows, a multi-runtime architecture, streaming chat with prompt caching, and per-job cost tracking that surfaces real unit economics before you scale.
