Environmental Systems Architect · AWS Certified · Duisburg / Remote
I help companies in energy, industrials and sustainability consulting build the cloud-native ESG data infrastructure that CSRD compliance actually requires — not just reports, but the systems behind them.
The problem
Most organisations approaching CSRD compliance reach for better templates and more sustainability staff. What they actually need is cloud-native data infrastructure — systems that collect, verify, store and report environmental data at scale, with audit trails that survive external scrutiny.
Spreadsheets and disconnected tools cannot do this alone. The companies that get ahead of the deadline will be the ones that treated ESG data as an engineering challenge, not a communications one.

About
I am Ejiro Elum — an environmental scientist by training and a cloud architect by practice. The combination is not accidental. After completing two master's degrees in environmental science and management, publishing peer-reviewed research in bioremediation, and working in HSE advisory and operational roles, I retrained in cloud architecture and earned my AWS Solutions Architect certification.
The reason the combination matters is straightforward: the organisations that most need cloud-native ESG infrastructure — industrial companies, energy firms, manufacturers — need someone who understands both what the environmental data means and how to build the systems that handle it. Most cloud architects have never worked in environmental science. Most environmental consultants have never designed a cloud architecture. I have done both.
I additionally completed a UX Immersion programme at KarriereFoundry GmbH in Berlin, which means I think about the human layer of the systems I build — not just the architecture underneath. For ESG platforms where non-technical stakeholders need to interact with complex data, this matters.
Based in the heart of NRW's industrial transition zone, I work remotely with clients across the EU, UK and beyond. I speak English (native), German (very good), and Urhobo (native).
