Session Three: The role of the Middle East in global bunkering:

A 13-year voyage through the turbulent waters of the trading and maritime sectors, I have not only navigated through challenges but have also anchored teams and operations securely amidst market storms. My current endeavor as the Chief Operating Officer and Trading Head at Oilmar DMCC since September 2020 epitomizes a legacy of turning tides in favor of organizational growth. My forte lies in crafting business narratives from scratch, akin to the flourishing logistics venture in UAE and the thriving Marine fuels trading business under the prestigious Oilmar Group, which burgeoned from a modest team of 3 to a formidable force of 50. My recent venture into scaling dry freight trading in 2023 is yet another testament to my unyielding drive towards unchartered territories.


My earlier stints include key roles at Kyto Global, Refinitiv LLC, Kamca Trading, and Hazel (Veritas) among others, where my responsibilities spanned from trading management to external contributing, always with a keen eye on the horizon for emerging market opportunities. My academic voyage commenced with a BS in Marine Engineering from BITS, Pilani, sailed through an MSc in Petroleum Engineering from Heriot-Watt University, and further bolstered by a professional certification in Forex & Futures Trading from Professional Traders Group.


Among my notable triumphs are the establishment of two robust business units that now contribute a substantial turnover of more than $500M, procuring substantial credit insurance along with lending facilities of $15M, and achieving a coveted Refinery valuation.

These accomplishments are not mere milestones but exemplify my enduring commitment to fostering growth and ensuring smooth sailing even in tempest markets.


My professional memberships with the Society of Petroleum Engineers (SPE) and the Royal Institute of Naval Architects (RINA, UK) further augment my resolve to stay abreast with industry evolutions and contribute to the collective maritime discourse. As I continue to navigate through the realms of trading and operational management, I bring to the helm a wealth of experience, a treasure trove of industry knowledge, and an undying zest to explore beyond the known horizons.
