Engineering& securitythat ships.
I build, secure and audit web applications, backend, frontend, architecture and infrastructure. Senior engineering and security for businesses across DACH and worldwide, plus coaching teams on AI agents, LLMs and Web3.
Security, architecture, and everything in between.
From auditing what you've already built to designing and shipping what's next, plus coaching your team on AI and Web3.
Security & Audits
Security reviews and audits across backend, frontend, architecture and infrastructure. Threat modelling, hardening, and finding what automated scanners miss.
Architecture & System Design
I design systems you can actually operate, from requirements and data flow to the trade-offs that decide whether something scales or breaks.
Infrastructure & Ops
Deep understanding of real-world infrastructure: servers, deployments, monitoring and the operational details that keep production healthy.
AI Agents & LLMs
Coaching teams and building with LLMs and AI agents, from first integration to production workflows that hold up under real use.
Full-Stack Engineering
End-to-end product builds in React, Next.js and Node, web2 and web3, frontend to backend, shipped and maintained.
Web3 & Blockchain
When you need it: DeFi, NFT marketplaces, DEXes and smart contracts on EVM chains, from a builder who's shipped them at scale.
One architecture, end to end.
From the client to the database, with the security, web3 and storage around it. The same shape underpins every product I ship.

Senior engineering you can trust.
I'm Gorden Kirisits, a senior full-stack engineer based in Salzburg, Austria. Before I wrote my first line of production code in 2018, I spent a decade in enterprise IT as an IT business analyst and ERP specialist, IREB- and ITIL-certified, designing systems and processes for large organisations.
That decade is my edge. I approach engineering from architecture first: I see the whole system, requirements, data flow, operations and the business behind it, not just the code. It's what takes my work as a developer to the next level, and it's why the things I build hold up.
Today my work centres on security and architecture: auditing backends, frontends, infrastructure and whole systems, alongside full-stack delivery for web2 and web3 clients, and coaching teams on AI agents, LLMs and blockchain.
Along the way I've shipped dozens of production applications and founded NitroDome, a Web3 gaming platform, which I built and led through to its acquisition by Warp Gaming.
I work with founders and businesses who want senior engineering they can rely on: clear communication, honest timelines, and software that holds up in production. I speak English and German and work with clients across the DACH region and worldwide.
