Lev Zhitnik
Full-Stack & AI Engineer | Web Apps, AI Systems, Automation Tools, and Practical Solutions
I build things, mostly from zero. I started in architecture and computational design, co-founded an urban-planning startup, and I'm now the technical co-founder of my second, aēv. I love new beginnings: a new problem, and people who are as excited about their work as I am about building.
Experience

Technical Co-Founder
aēv (AevArk)
A pet longevity lab. The only engineer on the founding team, building a new product with veterinarians and researchers.
Design and build the whole platform: four services spanning a Next.js client for owners and vets, a Node.js API (Hono, Prisma, PostgreSQL, Stripe) and Python processing (FastAPI), on Google Cloud Run with Pub/Sub.
Work with a team of veterinarians and researchers to build a data-driven longevity profiling system.
Build the AI workflows: multi-step LLM pipelines with validation and human review, for reading lab reports and writing results.
Own product, UI/UX design, infrastructure, CI and data work.
