Data Analyst freelance

I bring more than 17 years of experience in the oil and gas industry, primarily within the Pertamina Group, where I have developed extensive expertise in gas commercialization, LNG marketing, pipeline gas supply, and energy portfolio strategy across Indonesia’s industrial and downstream gas markets. Throughout my career, I have held several commercial and strategic roles in the natural gas value chain, including Commercial Manager for Pipeline Gas, LNG, CNG, and City Gas at Pertagas Niaga, where I was responsible for expanding gas markets, negotiating industrial gas contracts, and developing commercial strategies for gas distribution networks. My experience includes managing industrial gas customers, developing new gas demand with volumes exceeding several MMSCFD, and supporting the growth of gas utilization across manufacturing, energy, and hospitality sectors. I have also led commercial development initiatives for major industrial customers such as Danone (Sarihusada), Sinarmas Group, Sido Muncul, ceramics manufacturers, and hospitality sectors, while supporting the development of CNG transport infrastructure, LNG distribution, and pipeline gas networks in Western Java and South Sumatra. These experiences provided me with strong capabilities in gas market development, commercial negotiations, portfolio management, and strategic gas supply optimization. Currently, I serve as Senior Analyst for Gas LNG Marketing at PT Pertamina (Persero), where I focus on gas marketing strategy, technology innovation initiatives, and strategic energy partnerships. My work also involves supporting strategic portfolio alignment across the Pertamina Group and contributing to energy transition initiatives, including gas infrastructure expansion and downstream energy solutions. In addition to commercial leadership roles, I have been actively involved in strategic investment projects and technology development, including projects with capital expenditure exceeding USD 50 million and strategic initiatives such as research and technology development for energy solutions within Pertamina’s ecosystem. Academically, I hold a Bachelor’s degree in Chemical Engineering from Universitas Gadjah Mada, a Master’s degree in Management from IPB Business School, and I am currently completing my Doctoral degree in Management at Universitas Brawijaya, complemented by professional engineering certification and multiple international professional certifications in supply chain, risk management, and strategic management Thank you for your attention.   Best Regards,   Dliyaa Ul Haq +628111225093
