Legacy-to-Node / NestJS migration
Replace risky legacy paths with maintainable TypeScript services, using tests and narrow migration slices so the team keeps shipping while the system changes.
Proof: RWE Java-to-NestJS migration work.I help teams reduce delivery risk in migrations, data-heavy APIs, integrations, and tested React/Node systems for companies like Scout24, RWE, and NETS.
Best fit: long-term remote EU B2B contracts where production quality, measured performance, and clear senior communication matter more than another generic full-stack profile.
I am not positioning as a cheap task executor. The strongest fit is a team that needs a senior engineer who can enter an existing system, understand the domain, and move important work without adding chaos.

Proof: RWE Java-to-NestJS migration work.Profile slow flows, separate bottlenecks from guesses, improve data access, and keep production workflows responsive under real usage.
Proof: 65% faster APIs and exports cut from 45 minutes to 12.Ship product changes in mature systems where SEO, integrations, reviews, and coverage all matter to release confidence.
Proof: ImmoScout24 search, listing, SEO, and Iterable work.At 16 I won an internship contest in Galati and turned it into my first software job. I learned Linux and web development on real work before moving to Cluj-Napoca for Computer Science at Babes-Bolyai University, where I put formal structure around the practical habits I had already started building.
I have worked across payments, energy, real estate, e-commerce, and publishing, including DAX-listed companies and major European platforms. My strongest work is in backend-heavy full-stack systems: Node.js, React, databases, testing, integration work, and performance improvements that are measured rather than guessed.
I am looking for long-term remote EU B2B contracts where engineers own outcomes, communicate clearly, and care about maintainability. The best fit is a product or platform team with enough domain complexity to reward careful senior work.
Real problems, real decisions, real outcomes.
Shipped search/listing, SEO, and Iterable integration work inside a fully tested distributed platform where release quality and production safety mattered.
Reduced delivery risk in a Java-to-NestJS migration, profiled MongoDB-heavy data flows, and moved export processing into worker pools.
Rotated across enterprise domains, shipping React and Node.js systems for payments, telecom, and publishing clients with fast ramp-up and clear delivery habits.
