Founding Engineer & Architect: Web3, RWA & AI

Background

Three years as a founding engineer, shipping production financial infrastructure — the foundation for where I'm focused now: Real World Assets, secure financial systems, and AI-native enterprise software.

Founding Protocol Engineer

· Velvet.Capital

2022 – 2025

First technical hire at a startup. Set the architecture, engineering standards and security culture from a blank repo through 4 audited mainnet releases.

Software Development Intern & Thesis

· msg systems Research

2020 – 2021

Fresh out of university: my thesis was the planning work, then I joined as a working student for development, on a team with experienced leads and seniors — involved end-to-end early in my career.

B.Sc. Information Systems

· Technical University of Munich (TUM)

2016 – 2020

Bachelor's thesis on OSS license compliance evaluation, carried into the msg systems role above.

Four disciplines, one architectural mindset.

Web3 taught me to build financial infrastructure where mistakes are irreversible and audited by strangers. That's the discipline behind everything below — backend systems, production smart contracts, and Real World Assets, where I want to take that experience next.

Financial Systems & RWA

Tokenization, treasury custody and fee accounting from 3.5 years in production DeFi, plus extensive independent research into Real World Assets — Velvet's index-token architecture (proportional ownership as tradeable tokens) maps directly onto how RWA tokenization works.

Backend Engineering

Python and TypeScript backend systems — FastAPI, Express, PostgreSQL, multi-tenant architecture, RBAC, audit trails. My core day-to-day craft, and the discipline behind every project on this site.

Smart Contracts & Web3

Solidity, EVM, UUPS proxies, Chainlink oracles — 3.5 years shipping production contracts across four chains, nine audit cycles, $7M+ TVL secured.

AI-Native Building

I use AI to learn new stacks fast — this whole site, start to finish. Deep AI-infra judgment (model selection, cost at scale) is a growth area, but the interface-first architecture and verification discipline from Web3 transfer directly.
