An independent advisory practice based in Tokyo, serving maritime, industrial, and cross-border clients across Asia, the Americas, and Europe.
Get in touch →CMACH Consulting is the independent practice of Cesar Macher, a naval architect and MBA with more than four decades of international experience in shipbuilding, port operations, industrial machinery, and cross-border business development.
The work blends deep engineering fundamentals with commercial judgment, cultural fluency across four languages, and a current focus on how AI, IoT, and circular-economy thinking can be applied responsibly to maritime and industrial businesses.
Ship design, repair, and surveying. Port operations, towage, and marine logistics: shipyard management and technical-commercial translation between operators, yards, and equipment suppliers.
CNC manufacturing, factory automation, and production engineering. Procurement and import of industrial equipment: international sales support and OEM negotiations across Asia, the Americas, and Europe.
Practical adoption of AI, IoT, blockchain, and data-driven decision environments — grounded in what works on shop floors, in ports, and aboard vessels, not what looks good in a slide deck.
Circular-economy strategies and environmental performance applied to shipbuilding, maritime operations, and industrial manufacturing. Informed by recent executive education at the University of Cambridge Judge Business School.
The career began in naval architecture in Rio de Janeiro — classrooms at the Federal University, fluid mechanics labs, and early hands-on experience in structural surveying at Bureau Veritas and yacht design at DM Náutica. That foundation, combining engineering rigour with shipyard fluency, has shaped every chapter since.
From Rio, the path moved to Peru, where a field supervisor role at SIMA Shipyard, Peruvian Navy, grew into general superintendent responsibilities covering modular tanker construction and floating dock projects. It was the first experience of leading large technical teams — and of teaching naval architecture to company personnel and merchant marine students. A JICA scholarship then brought a first posting to Japan in 1985, with graduate training at the Overseas Shipbuilding Cooperation Center in Yokohama and at Ishikawajima-Harima Heavy Industries in Aioi — the start of a long relationship with this country.
An MBA from Grand Valley State University in Michigan followed, opening the door to industrial business development. The next chapter ran through Chicago and then Nagano with Miyano Machinery — a CNC machine tool manufacturer — where the work spanned planning and building a new factory in Iwate, international procurement and OEM negotiations across Asia and Europe, and sales engineering for the Latin American market. Many years in corporate Japan built both the technical depth in factory automation and the cultural fluency that still underpins the practice today.
A Canadian chapter followed, with independent consulting in Vancouver — including shipbuilding project management for Vancouver Shipyards — and change management work at Suncor Energy during a large-scale corporate reorganization. CMACH International was founded in Tokyo in 2011 to consolidate this trajectory into a standing consulting presence for maritime and industrial clients across the Americas, Asia, and Europe. CMACH Consulting continues that work today as a focused independent practice.
Recent executive education has sharpened the forward-looking side of the work: Blockchain Technologies: Business Innovation and Application and Internet of Things: Business Implications and Opportunities at MIT Sloan Executive Education in 2021, and Circular Economy and Sustainability Strategies at the University of Cambridge Judge Business School in 2023. These are not credentials on display — they are the frameworks used day to day to help clients make sense of what comes next.
Independent maritime and industrial consulting practice serving clients across the Americas, Asia, and Europe. Focus areas include shipbuilding and port operations, industrial machinery and factory automation, digital transformation, and circular-economy strategy.
Shipbuilding project management work for Vancouver Shipyards, followed by change management support for Suncor Energy through a large-scale corporate reorganization. First extended exposure to the oil sands industry and to enterprise-scale transformation programs.
CNC machine tool manufacturer (lathes and turning centers). Roles across international sales engineering for the Latin American market, procurement of international components and OEM supply agreements across Asia and Europe, and applications engineering for high-volume factory automation.
Import of industrial equipment and architectural materials for a new manufacturing plant in Iwate. Training in CNC programming and machine operation, precision metrology instrumentation, CAD, and JIT / TQM production disciplines.
Coordinated plant and equipment expansion, joint venture, and OEM projects across Miyano's worldwide subsidiaries. First entry into the group after completing the MBA at Grand Valley State.
Grew from field supervisor to general superintendent role, implementing a shipbuilding planning model based on modular construction techniques for tanker and floating dock projects. Taught introductory naval architecture to company personnel and merchant marine students.
Training in structural and machinery surveying for ships and offshore structures, including non-destructive testing. Naval architectural calculations and design drawings for powered yachts and FRP sailboats. Laboratory work in applied fluid mechanics and hydrodynamics at UFRJ.
