Secure software. Swiss-made.
Teams I've built for, audited for, and worked alongside.
PoC for the Staged Proposal Processor plugin
Technical advisor
Smart contract security
CCIP integration & contract audit
Technical advisor for their Solana implementation
Internal RAG-based AI assistant
Built like a Swiss watch. Coded for the modern stack.
Code that runs, scales, and holds up under pressure.
I work with teams that ship real products and want them fast, clean, and secure — whether you’re starting from scratch or scaling something that already exists.
Production-grade smart contracts for Ethereum and any EVM-compatible chain — clean, tested, and secure.
From tokens to custom protocols and cross-chain integrations, I turn blockchain ideas into working code.
Targeted security reviews for EVM smart contracts, focused on logic flaws, reentrancy, and edge-case exploits.
In my Frankencoin audit
I uncovered critical minting and challenge vulnerabilities and worked with the team to fix them.
Prepping for mainnet or want a second pair of eyes on a release? I’ll help you ship with confidence.
Maintainable, high-performance APIs, background jobs, and integrations — built in TypeScript and shaped around your product.
LLM features that save real time, not demos.
From retrieval-based (RAG) assistants over your internal docs to custom tooling — with OpenAI, open-source models, or something custom.
I like new ideas and weird problems — AI tooling, automation, internal systems. If it’s technically interesting, I’m all ears.
Battle-tested: 10+ years building software that ships
Deep stack: Solidity, TypeScript, AI, cloud infra, and security
Sharp eye: Code quality, clean architecture, audit mindset
Flexible: I adapt to your stack, team, and workflow
Straightforward: Clear scope, direct communication, zero fluff
From first call to handover. No surprises.
A free 30-minute call about your goals, timeline and constraints. No commitment.
A written scope with deliverables, timeline and price, so you know exactly what you get.
Short feedback loops and regular updates. I work in your repo, with your tools and your team.
Tested code, docs and a walkthrough. For audits, a written report and a review of your fixes.
A decade in tech, and I’m just getting started.
Hey, I’m Mathias — a developer based in Switzerland with 10+ years of experience across IT, automation, and emerging tech.
I bring a Swiss mindset to my work: precision, reliability, and quality that lasts. Whether it’s smart contracts, backends, or AI tooling, I help teams turn ambitious ideas into robust, secure software — and I think through the architecture, not just the code.
Custom Development From smart contracts to AI integrations, I build tailored solutions that meet unique business needs.
DevOps & Automation CI/CD, Kubernetes, ArgoCD, Github Actions, … — I help teams streamline and scale with confidence and in their preferred tooling.
Security-Focused Engineering I take software security seriously. Whether it’s smart contract audits or designing fault-tolerant infrastructure, I build with safety in mind.
Languages: TypeScript, Solidity, Python, and a little bit of Rust
Infrastructure: Kubernetes, ArgoCD, Terraform, Github Actions, CircleCI, and many more
Mindset: Clean code, automation, and always learning
nexcite.ai
Nexcite is an AI-powered research tool that lets you upload documents or search the web and get answers with every claim traced back to its exact source — no more hunting through papers to verify a citation. Built for researchers, PhD students and academics who need precision, not hallucinations. EU-hosted, currently in free beta.
Frankencoin CCIP Integration
Brought the Swiss Franc–backed stablecoin (ZCHF) to multiple chains with Chainlink CCIP integration.
Frankencoin Smart Contract Audit
Conducted a full security review of the initial ZCHF contract system, uncovering critical minting and challenge vulnerabilities — and worked with the team to address them.
RAG-based AI Chatbot @ TX Group
Built an internal AI assistant that helps employees get instant answers from internal documentation using Retrieval-Augmented Generation.
Building cool stuff starts with a hello.
