SYSTEM
I build and modernize software your business depends on.
New web products built right from day one.
Legacy systems rescued, secured, and modernized.
What I do
- 01
Fullstack Development
New websites, web apps, and browser-based products built on a modern stack. TypeScript, Next.js, clean architecture — built to last and easy to hand off.
- 02
System Audit
Full-stack assessment of your codebase, infrastructure, and security posture. You get a prioritized remediation roadmap — not a report that gathers dust.
- 03
Refactoring & Migration
Incremental modernization that keeps your system in production throughout. I move the foundation while the building stays open.
- 04
Security Hardening
Vulnerability triage, dependency remediation, secrets management, and threat modelling. Compliance-ready without the consultant theatre.
- 05
UX Modernization
Replace brittle frontends with fast, accessible interfaces. Same domain logic — dramatically better experience for your users and your team.
Engineer. Auditor. Developer.
I'm Niclas — a web engineer based in Germany. I build web products and modernize the systems companies depend on. I've been doing this since 2021, first as a freelancer, now alongside graduate studies in Computer Science at TU Darmstadt and a working student role in cybersecurity at FTI Consulting.
What shapes how I build isn't only engineering experience. Three years inside EY's IT audit practice — reviewing security controls, infrastructure, and financial systems for major aviation and fashion companies across Europe — gave me a perspective most developers don't have. I know what breaks at scale, what gets flagged in a compliance audit, and what 'secure by default' actually requires in practice.
