Das is a 1991-batch officer of the Indian Defence Accounts Service (IDAS) and an alumnus of Utkal University, Bhubaneswar, and ICPE, University of Ljubljana, Slovenia.

During his career, he has led numerous initiatives in procurement policy, audit and oversight mechanisms, budgeting, and expenditure monitoring. His professional development has been supported by advanced training at premier global institutions, including IIM Bengaluru and Duke University, according to a Ministry of Defence release.

He has served in significant roles across the Ministry of Defence, Service Headquarters, and field formations. Notable appointments include Director at the Ministry of Water Resources, Additional Financial Adviser and Joint Secretary in the Ministry of Defence, Principal Integrated Financial Adviser at Army Headquarters, and Special Controller General of Defence Accounts at CGDA Headquarters.

In December last year, the 2024 batch of Indian Defence Accounts Service probationers met President Droupadi Murmu at Rashtrapati Bhavan. Addressing the officers, the President highlighted the importance of their role in managing financial resources for the Indian Armed Forces and allied organisations.

She stated, “From budgeting and accounting to auditing, payments, financial advice, and ensuring transparency in defence expenditure, their role directly impacts operational readiness and the development of defence infrastructure.”

The President advised the officers to recognise the unique challenges, hardships, and operational realities faced by the Armed Forces, noting their position as the principal accounting and financial authority of the Defence Services.

According to the Ministry of Defence release, President Murmu remarked that the current era demands quicker, smarter, and more accurate decision-making due to the evolving geopolitical environment and emerging security challenges. She emphasised that business processes are becoming more complex and technology-driven, requiring the Defence Accounts Department to continuously adapt, innovate, and modernise.

She also stressed the need to support the Government of India's ‘Atmanirbhar Bharat Abhiyan’ by encouraging indigenous production, strengthening local supply chains, and promoting domestic industry. Officers of the Indian Defence Accounts Service can contribute significantly to building a self-reliant and resilient defence ecosystem.

The President urged IDAS officers to remain lifelong learners, stay curious, and embrace change with confidence. She highlighted that “the true measure of service lies not in position or recognition. Instead, it lies in the steady contribution they would make to the effective functioning of institutions and the welfare of citizens.”
