Valentin Vago is a Berlin-based managing director and software engineer with 14 years of professional experience and two decades of hands-on web craftsmanship dating back to the Netscape/IE era. He blends front-end expertise (notably on BPMN/DMN projects like camunda and bpmn-io) with product-minded systems work, focusing on quality, automation and developer ergonomics. After a decade as a freelance full‑stack developer for NGOs, researchers and SMEs, he spent the next ten years scaling front-end practices in startups and developer tooling. Valentin builds both user-facing UI polish and internal processes—shipping styled, accessible components while improving testing, linting and architecture across JS/TS codebases. He now runs his own firm to package services and products that reflect his dual interests in creative tooling and sustainable projects that protect the nature that inspired him. An uncommon strength is his combination of art-and-design training with deep practical engineering, which shapes pragmatic, well-crafted digital experiences.
