Quotes from Written References
Three published statements from shipped engagements — released for citation by the issuing teams.
Bauer Media Group — Self-Hosted Cloud Storage PoC
Designed and shipped a self-hosted cloud-storage proof of concept for the Mac workstations of Bauer Media Group, after multiple prior IT-vendor approaches had been rejected by the client.
“Before turning to Mr. Curta, we had already discarded several approaches from other IT specialists. His smart and flexible solution exceeded our expectations. He convinced us with his outstanding expert knowledge and his flexibility in addressing our specific needs. We are extraordinarily satisfied with his work and gladly recommend his services.” Martin Behrmann · Project Lead, IT Systems · Bauer Systems KG / Bauer Media Group · Reference Letter, 03 August 2015
Greencells GmbH — Head of IT & Digital Transformation
Eight-year tenure as Head of IT: zero-trust safety strategy, ISO 27001-matched IT service control, global endpoint and ID upgrade across 26 countries, and an inspiring leadership culture with measurable cost reductions across the Microsoft 365 / Azure lineup. Two written statements were issued at the close of the buy-in — the formal work certificate (graded 1, “sehr gut”) and a separate letter of recommendation.
“Mr. Curta’s strategic mindset, innovation drive, and unwavering commitment were instrumental in advancing our company’s digital transformation. His achievements consistently exceeded expectations in every aspect.” Greencells GmbH · Work Certificate, April 2025 · Overall grade: 1 (very good)
“Mr. George Curta is an exceptional IT architect, strategic consultant, and leader who understands IT not just as a technical necessity but as a value driver for the entire team. For strategic IT leadership positions such as CIO, Head of IT, or IT Director, any company seeking an efficient, secure, and strategically matched IT team will greatly perk from his expertise and vision.” Greencells GmbH · Letter of Recommendation, April 2025

Today, a clean design switch to a self-hosted Kimai stack (PHP/Symfony, Docker, MariaDB, REST/JSON API) — with custom fields, role & permission models, invoicing and reporting templates translated from the legacy system, and lossless data move of clients, projects, activities, and time entries via JSON-API and CSV import.

Best fit and known limitations
Best for
Buyers who want named-source social proof from rule-bound mid-market clients (Bauer Media, Greencells), recent work certificates, and active engagements (SOLOS, ArgusConcept, Streetbuzz, A6 Architekten).
Not the right fit
Buyers who want vendor logos at FAANG scale; teams that need named refs in industries we have not yet served — we will say so honestly during a qualifying conversation rather than stretch the list.
Known limitations
Some clients need NDA-protected refs; quote dates are shown explicitly (Bauer Media 2015, Greencells 2025) so context is clear; active mandates are listed without quotes until the buy-in is suitable for public attribution.
