Wolf-Tech is a Berlin-based engineering consultancy founded by Sandor Farkas. We bring senior-level PHP/Symfony and React/Next.js engineering to teams that need delivery confidence, not bench-warmers.
Founder & Lead Engineer
18+ years of full-stack engineering across PHP/Symfony and React/Next.js. Specializes in legacy modernization, performance audits, and senior engineering leadership for SaaS and Mittelstand teams. Based in Berlin, working across the DACH region and internationally.
LinkedIn →Sandor has been writing production software since 2006, long enough to have lived through the full lifecycle of technologies that are now considered legacy, and to understand why so many systems accumulate debt over time.
Wolf-Tech was founded in 2006 and is based in Berlin. Sandor works with clients across Germany and the EU, in English and German. Today the focus is on companies whose business-critical PHP or JavaScript software lacks developer capacity: because there is no in-house developer, the only developer has left or is out sick, or a developer role is still open.
On the backend the focus is PHP, mainly Symfony. On the frontend it is JavaScript and TypeScript with React and Next.js, plus Node.js. Around that: MySQL, PostgreSQL, Docker and CI/CD. Older versions such as PHP 5 or 7 are no reason to turn a project down.
Many engagements start with an existing codebase: migrating aging PHP, untangling monoliths, or introducing modern tooling to teams that have worked with constraints for years. Clients are mostly mid-size European companies that need a reliable technical partner rather than a short-term contractor.
Projects have covered FinTech, healthcare, e-commerce, real estate, education and travel. Right now Sandor is modernizing 15-year-old legacy software in the medical sector while it stays in production.
Selected projects are described in the case studies →Sandor is an active member of uplink, a network of more than 4,000 freelancers.
Sandor writes the articles on the Wolf-Tech blog, in English and German. They cover legacy modernization, PHP and Symfony, Next.js and React, code quality, DevOps and software architecture.
