Razvan Mihailescu

Full stack blockchain developer. I started competing in hackathons to learn fast — shipping real things under pressure turned out to be a better education than anything structured. That habit stuck: I build across the full stack (frontend, backend, smart contracts), use AI as a core part of my workflow.


Work

Full Stack Blockchain Developer — Astrarizon (May 2025 – present)

Building Pulsar.Money — a crypto super-app covering trading, yield vaults, gamification, quests, and payments. 500K+ users, 7M+ reached across whitelabel deployments.

My work spans Next.js frontend, NestJS/Postgres/Redis backend, and Solidity/Move smart contracts. Things I've shipped here:

  • Passive yield vault system (Earn module) — contracts, backend, frontend
  • Quest engine, leaderboards, points campaigns, and profile system
  • Whitelabel engagement portals for external partners on EVM and Aptos
  • Campaign infrastructure running across 150+ partner projects

Featured Project

Autark — ETHRome 2025, Privacy Track

A DevSecOps framework for frontend deployments built on Safe + ENS + IPFS. The problem it solves: a single compromised developer can push malicious code through an automated CI/CD pipeline in minutes. Autark adds a multisig approval checkpoint before anything goes live, and cryptographically locks every deployed version via ENS NameWrapper fuses so it can't be modified afterward — not even by the Safe signers.

Batched Safe transactions handle subdomain creation and content-hash setting atomically, so rejected proposals don't waste version slots. Ships as a CLI that plugs into GitHub Actions and git hooks.
