Corporate Accounts


Having worked for many years in the Renewable and Fixed-Income sector I watched both industries change and grow. Started as everyone as a (junior) sales-trader and eventually becoming a manager-director and partner, I’ve seen most aspects of the different front-office tasks and roles. It is with great please and pride that currently I am, together with a great team of industry experts, developing Caely Renewables into a solid business partner for companies looking to cut their Greenhouse Gas emissions.

Poland & CEE


During my time as an analyst, trader and originator, I had the opportunity to observe the dynamic development of energy markets in CEE countries. I cooperated with various entities forming this sector and I think the biggest challenge they are currently facing is the transition towards renewable energy and sustainability. My mission is to help them reach their environmental goals by providing the best trading opportunities and advisory.

Physical Renewables Trader


A wise man once said, “Progress is impossible without change, and those who cannot change their minds cannot change anything.” After having worked several years for an oil major, I decided to join Caely Renewables to contribute to that change and be part of our journey to net zero. My job as a Biofuels Trader is to source and trade sustainable feedstocks for biofuel production with a focus on waste materials and residues.
