Mr Levente Esztergály

Sustainability consultant, LEED GA
Energy engineer-economist

As an energy engineer-economist I consider equally important a solution’s technical and economic feasibility. Based on this sentiment, I started in the last semesters of my studies to work on energy efficiency projects. In multinational companies first at KPMG Advisory I partook in company valuation, market study, analytical and PM projects. After that I at the Hungarian oil giant MOL, I had responsibilities in CAPEX and project&program management, Business planning, strategy creation and Top management reporting and Stage Gate system ownership. I also positioned myself towards the field of IT when I joined an IT developer company with focus on energy industry companies. Here as a business analyst my primary goal was to understand, translate and potentially optimize the business needs of the client and represent that need towards the developer team. At a certain point, partially due to the emerging trend of climate protection, ESG, sustainability and alike, I decided to acquire an expert level degree at the LEED green building certification system, called LEED Green Associate.



Mrs Hajnalka Gyenge

I have been a member of the MN6 team since October 2022, as a professional assistant. I am a qualified accountant, business planner and statistician.

In my previous jobs, I focused on complex thinking and process optimisation, which is essential for accurate work. The main aspect of joining MN6 was, that I wanted to be part of a team, where I could support professionalism with the knowledge I had already acquired.

The focus of my past years was to realise a dream that was born out of necessity. We created a foundation, with the aim to provide schooling for children with disabilities, while at the same time providing development opportunities for others, creating jobs and establishing links with organisations and partner institutions. We set out to realise our plans with a strong belief, without previous knowledge or capital. Promoting acceptance was a priority for us. All these noble goals gave us the strength and perseverance to work beyond our comfort zone and create a functioning organisation from scratch.

Currently, at MN6 Energy Agency, I build on the previously obtained above knowledge and work in several areas such as relationship management, process optimization, data collection, while supporting the company’s operations in all aspects.
