I Modernize Systems
That Cannot Go Down.
Senior backend and platform engineer in Aachen. I take legacy systems into services, teams into modern practice, and platforms into production that I then operate: Kotlin, Spring Boot, Kubernetes, TypeScript and React. Where teams build with AI, I build the guardrails that keep what ships defensible. Open to senior roles across the EU and remote worldwide.

Complex is cheap. Simple takes years.
Five products. In production. Anyone can demo. These run: two live with real users, three shipping toward launch, each with a written case study one click away.

“He is an excellent mentor, always willing to share his knowledge and help others grow. No matter the challenge, he always finds efficient and effective solutions. He would be an invaluable asset to any organization.”
Richa Deshpande · Worked with Edvard on the same team
“I personally learned a great deal from him about cloud architecture and Spring Boot, thanks to his patient and thorough explanations. I highly recommend Edvard to anyone looking for a talented, driven, and collaborative software developer.”
Sebastian Kaiser · Worked with Edvard on the same team
“Beyond his brilliant work as an engineer, he is a natural leader and an indispensable team player. Any team would be lucky to have him on board.”
Nikita Moritz · Worked on the same team, reported to Edvard directly
Still running. That's the point. Development started May 2025, live in 2026, running since. The receipts sit in the card below.
DanceClub

Modular monolith · 65 Gradle modules · 10 Postgres schemas · 4 Next.js frontends
Self-hosted end to end. CI/CD on every push. No on-call rotation, no SRE team, it simply hasn't needed one.

One monolith in. Twelve services out. Zero downtime. Not my product, my employer's: a German B2B SaaS in Aachen. Three years leading the decomposition and mentoring the team that runs it.

The full track recordFour things you get on day one. Not a list of tools. The scale I have already run, the ownership I already carry, and the range that lets me take the whole problem instead of a slice of it.
Tenants in one system
Invoice processing automated end to end for 50+ enterprise tenants: a scanned document or an inbound email through issuer and tenant resolution to an approved payment. Mercedes-Benz is among the clients running on it.
Person team taken off legacy
Moved a team of legacy developers onto Spring Boot and a two-week release cadence, mentored three engineers directly, and introduced the quality gate that cut code-quality violations by more than 60%. Also took the company off-premise to the cloud.
Applications built and operated
Kubernetes, GitOps and the observability under it across 8 Linux hosts, as the sole operator and on call for all of it. That includes catching a 13-day silent certificate renewal failure that every probe had reported as healthy.

A decade of building things people actually find and use, from client SEO work early on to a platform across 15 localized markets with roughly 1,500 indexed pages. I know what happens to software after the deploy.
AI writes the code now. So what are you hiring for? The honest answer, with receipts. Generating code got cheap. Deciding what survives, and being accountable when it doesn't, did not.
Anyone can demo. Almost no one can keep it running.
AI gets you to a working demo in an afternoon. It doesn't write the migration, notice that backups stopped six weeks ago, or carry the pager at 3am. Production is a discipline, not a deploy button: tests against real databases, migrations, monitoring, rollback plans, the boring parts that decide whether you still have a product in year three.
AI is brilliant in an empty repo and useless in yours.
Your core system carries fifteen years of undocumented business rules, and the revenue flows through it. That context doesn't fit in a context window, and the risk tolerance is zero. Brownfield work is judgment, sequencing, and nerve. It's the work most engineers avoid and the work I'm best at.
I don't just use AI. I direct it, and I teach teams to.
Two years building agent workflows, MCP servers, and correction protocols. My own agent infrastructure runs my deployments, and I built PLMHub so AI-generated systems stay understandable to the humans who own them. One person with Copilot gets faster. A team with the right discipline compounds.
Prefer to contract? Where to start
Day rate on request · B2B · Remote EU · NRW on-site
Three steps. Hire me or contract me. The same discipline either way: a conversation, working software in week one, and knowledge your team keeps.
Conversation
Thirty minutes on your actual problem. Role, contract, or rescue, we scope it straight.
Ship in week one
A real ticket in the first week, not onboarding theater. Decisions documented as I go.
Production, together
Working software in production and a team that understands it. No knowledge silo, no PDF.
Sounds like your team?
A 30-minute call, no pitch. Hiring, contracting, or just a hard problem, bring it.
