Full-Stack Development
From first idea to production-ready system — frontend, backend, API design, deployment. Web applications, internal tools, API services, database migrations, and codebase modernization.

I'm Tim
Witter
I build production-grade software from first idea to shipped product — across web, mobile, Web3 & infrastructure. From Rust backends to Solana dApps, all running on NixOS.

// 01 — What I Do
Services
End-to-end development across four core areas. Clean code, on time, greenfield or legacy.
Mobile & Web3
Cross-platform apps with React Native and Expo for iOS & Android. Active builder in the Solana Mobile ecosystem — compressed NFTs, wallet integration, and the dApp Store.
AI-Integration
LLM integration into existing systems — custom API pipelines, production prompt engineering, automated content workflows, and multi-agent architectures with OpenAI and Anthropic Claude.
DevOps & CI/CD
Automated build and deployment pipelines with Docker, GitHub Actions, NixOS, and Infrastructure as Code. Reproducible builds, automated testing, declarative environments.
// 02 — Selected Work
Projects
Real products shipped to real users — learning by building, not by following tutorials.

About me
I'm a developer based in Austria, building software across the full stack — from declarative NixOS infrastructure to mobile apps shipping to the Solana dApp Store.
My approach: learn by building real products. Every project goes deeper. Right now I'm focused on Rust, blockchain/Web3, and mobile development — where systems-level thinking meets user-facing products.
I care about privacy-first, offline-capable software with no cloud lock-in. Code should be reproducible, environments declarative, and builds hermetic. Whether it's a greenfield product or a legacy modernization — I deliver clean, maintainable code on time.
Structured, independent, solution-oriented. Effective as a solo developer and in agile teams. Clear communication, on-time delivery, full commitment.

// 05 — How I Work
Process
From requirement to release — a clear, efficient path.
Understand
Deep-dive into the problem space, constraints, and goals before writing a single line.
Architect
Choose the right stack, design the data model, and plan for scale and maintainability.
Build
Iterate fast with clean code, CI/CD from day one, and continuous feedback loops.
Ship
Deploy to production with reproducible builds, monitoring, and documentation.
