Hey there! I'm Rein, also known online as Retro Dev. I'm a versatile software engineer with a passion for building cool stuff! I specialize in AI systems and autonomous agents, DeFi development, smart contracts, blockchain infrastructure, and web development—with a background in Unity game development and C#.

In my 10 years of experience, I've not only built the tech but driven projects to success—launching products that have reached 50M+ market caps. From top-charting blockchain games (Untitled Platformer hit top 10 on dAppRadar in 2023) to DeFi protocols and infrastructure, I've developed multiple SDKs, written extensive technical documentation, and delivered real results.

These days most of my focus is on AI. I build agentic systems end to end—LLM-driven decision engines, autonomous agents that run unattended on a schedule, the risk guards and data pipelines underneath them, and the chat interfaces on top.
