Projects that were stuck – and are running now
No glossy sales decks, just real starting points: an old PHP monolith, a Java 8 system without tests, and an AI prototype without security. Here is what became of them.
🔹 Fixed price. 4–6 weeks delivery. You keep the code.
❌ "Our frontend is stuck inside the old PHP monolith"
❌ "Every change in the Java 8 system is a risk"
❌ "The AI prototype has no auth and no tests"
✅ Solution: step-by-step modernization without downtime
My Specializations
Three projects, three rescued systems
Every case study shows the starting point, the approach and a measurable result. Pick the project that is closest to your situation.
PHP monolith → React/Next.js
Task: A modern frontend for an old PHP backend – without replacing the backend.
Java 8 → Spring Boot 3
Task: A 15-year-old Java 8 monolith needed to be modernized step by step.
AI-generated code made production-ready
Task: An AI-generated prototype had to become production-ready – with auth, tests and deployment.
What you actually end up with
No buzzwords – just numbers that change something in day-to-day business.
🔧 Subcontractor for agencies
You have a client who needs legacy modernization or AI refactoring – but your team has no capacity or expertise? I work as a reliable subcontractor for agencies and IT service providers. Fixed price, clear communication, on-time delivery – and you stay the single point of contact for your client.
- Confidential and on behalf of your agency – no poaching of end clients
- Firm deadlines and a clearly defined scope before kickoff
- Handover with documentation, tests and a clean Git history
From chaotic to production-ready
📉 Before: PHP monolith with 12k lines, no testing, constant outages.
📈 After: API-first architecture + React dashboard, outage rate −95 %.
🤖 Before: AI-generated React app without a backend – data stored only in localStorage.
⚡ After: Complete Java/Spring API, PostgreSQL, JWT auth + clean UI.
Because reliability matters more than hype
- Fixed price instead of hourly risk – you know the number before we start
- Ongoing operations keep running – the migration happens without downtime
- You keep the code: properly documented, tested and ready to hand over
- Direct communication with the developer – no agency layers in between
Instead: architecture, stability and a UI that actually works.
"I already had 3 AI prototypes built – not one of them runs in the cloud."
– That is exactly where I take over.
Your technical sparring partner for difficult software projects
I support companies when legacy systems slow everything down or AI prototypes are not production-ready. The projects above came out of exactly these situations – with clear architecture, solid tests and traceable results.
Stack: Java, React, PHP, Spring Boot, Node.js • Approach: pragmatic, transparent, production-focused.
