Ron Mujaj

I build AI products end to end, from the agent runtime to the cloud it runs on. Engineer at TMLS.NYC, a New York venture studio.

AI-native engineering

I have worked with Claude Code and OpenAI Codex since their launch, and they are at the core of how I build.

Multi-agent workflows, custom skills, hooks, and MCP integrations. Agents carry the volume; I own the architecture, the review, and the result.

On the model side: prompt and context engineering, retrieval and reranking, evals and LLM-as-judge, local and on-device models, and early hands-on work with new model types like Jev by TypeSafe for fast, calibrated decisions.

Selected work

AI product suite · TMLS.NYC01

Marietemariete.ai ↗

Ten AI products on one shared agent platform, from multi-agent simulation and competitive intelligence to an assistant that runs fully offline on the phone.

I build the agent runtime and the products on top of it, plus the shared login, design system, and release pipeline behind all of them.

  • AI agents
  • Multi-agent systems
  • On-device LLMs
  • Python
  • Next.js
  • React Native
  • Supabase
Creator platform · client project02

VASTvast.app ↗

A home for creators and their communities: livestreams with chat and replays, scheduled shows, creator payouts, and automated content moderation.

I own the cloud infrastructure and the delivery pipeline, so every change goes from code to production tested and reproducible.

  • AWS
  • Infrastructure as code
  • CI/CD
  • Live video
  • Python
  • Laravel
  • Next.js
Crypto media · editorial platform03

Bitcoin2Go

Comparisons and ratings of crypto exchanges, wallets, brokers, and more, across eight product categories.

I replaced the editorial team's spreadsheets with a full-stack dashboard. One configurable scoring engine rates every product live while editors type.

  • Next.js
  • TypeScript
  • Supabase
  • PostgreSQL
  • System design
EVM Layer 1 · TMLS.NYC04

Incentivincentiv.io ↗

A blockchain built around native account abstraction, so wallets behave like normal accounts instead of seed phrases.

I added passkey signing (WebAuthn, P256) to the chain's Ethereum client and brought it into the ERC-4337 bundler.

  • Go
  • Ethereum clients
  • Account abstraction
  • Cryptography
