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.

What I do

Security, architecture, and everything in between.

From a brand-new website to auditing, designing and shipping complex platforms, plus coaching your team on AI and Web3.

Web & Frontend Design

01

Clean, modern websites for businesses, coaches and creators, designed and built to be responsive, fast and easy to run. From a fresh landing page to your full online presence.

02

Full-Stack Engineering

End-to-end product builds in React, Next.js and Node, web2 and web3, frontend to backend, shipped and maintained.

03

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.

04

Security & Audits

Security reviews and audits across backend, frontend, architecture and infrastructure. Threat modelling, hardening, and finding what automated scanners miss.

05

Infrastructure & Ops

Deep understanding of real-world infrastructure: servers, deployments, monitoring and the operational details that keep production healthy.

06

AI Agents & LLMs

Coaching teams and building with LLMs and AI agents, from first integration to production workflows that hold up under real use.

07

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.

Websites & Web Design

Need a website that just works?

Not every project needs blockchain or a security audit. Sometimes you simply want a beautiful, modern website that loads fast, works on every phone and actually brings in enquiries. That's something I love to build too.

  • Custom design, no templates
  • Responsive on every device
  • Fast loading & solid SEO basics
  • Clear content & call-to-action
  • Handover or ongoing care

How I build

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.

About

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.

A clear path from idea to launch.

01

Discovery

We scope the problem, goals and constraints. You get a clear plan, timeline and fixed expectations before any code is written.

02

Build

Iterative, transparent delivery. You see progress every week, with working software at each step, never a black box.

03

Ship & support

Launch, monitoring and a clean handover. I stay available for maintenance and the next iteration.
